It is strictly prohibited to use it beyond the specified range; Measurement category II defined in accordance with IEC 61010-031 standard cannot be used for category III or IV scenarios. When combined with equipment/accessories of different measurement categories, the lower category shall prevail.
Grounding requirements: The protective grounding terminal of the oscilloscope must be grounded, and the grounding wire of the probe must be connected to the grounding potential. Double grounding can effectively prevent the risk of electric shock and ensure measurement safety.
Electric shock protection: It is strictly prohibited to operate with wet hands or use the probe when it is damp; Be cautious of electric shock when connecting the tested device, and do not remove the probe from the oscilloscope when connecting it to the tested device; Avoid contact with exposed circuits and remove metal jewelry such as watches and rings during operation to prevent accidental electric shock.
Environmental restrictions: Do not use in damp, dusty, or flammable/explosive environments to prevent equipment failure or safety accidents; In terms of altitude, the working altitude should not exceed 2000m, and the storage altitude should not exceed 15000m; the working temperature should be between 0-50 ℃, the storage temperature should be between -40~71 ℃, and the humidity should meet the linear decreasing requirement of 80% (≤ 31 ℃) to 40% (50 ℃) to avoid environmental factors affecting measurement accuracy or damaging equipment.
Equipment status: If there is suspicion of probe damage (such as torn signal cables or exposed internal metal), immediately stop using and contact the dealer for repair; It is strictly prohibited to disassemble or modify the probe. Yokogawa shall not be held responsible for any malfunctions caused by unauthorized modifications; Strict adherence to the maximum input voltage limit (1000 Vrms) is required. When the oscilloscope input is coupled to AC, the DC voltage input by the probe will be synchronously applied to the oscilloscope input, ensuring that it does not exceed the maximum input voltage of the oscilloscope.
Product Overview and Configuration
（1） Product Features
701944 and 701945 are both high-voltage probes with a 100:1 attenuation ratio, and their core advantages include:
Probe tip design: Spring type tip (pre installed) can reduce pressure on the tested device, prevent sliding on the surface of the circuit board, and provide better stability when tilted for use; There are also options for rigid tips and clamp tips, suitable for different measurement scenarios.
Compatibility: Suitable for oscilloscopes with an input impedance of 1M Ω, the probe ID pin can be automatically recognized by the oscilloscope, and the oscilloscope attenuation ratio can be automatically set to 10:1 (manual adjustment is required if not automatically set).
Rich attachments: Provides a variety of standard and optional attachments to meet different measurement needs, and supports accessory replacement to extend the service life of the probe.
（2） Configuration List
Standard accessories: including probe body (701944/701945), spring tip (pre installed), rigid tip, clamp tip, insulation cap, protective cap (pre installed), grounding wire (22cm), color markings (4 colors x 3 pieces), adjustment tools and manual. All accessories must be confirmed complete and undamaged after unpacking to avoid affecting use.
Optional accessories: including flexible adapter, 4mm plug grounding wire, and safety crocodile clip, which need to be purchased separately and can be flexibly selected according to the measurement scenario.
Replacement accessory set: Two sets are available, “Accessories Basic” (B9852HK) including 2 spring tips, 2 rigid tips, 2 clamp tips, and 2 grounding wires; The “Accessories HV” (B9852HL) includes one flexible adapter, one 4mm plug grounding wire, and two safety crocodile clips, making it easy to replace accessories in bulk after wear and tear.
Operation process
（1） Basic Connection
Connection between probe and oscilloscope: Connect the BNC connector of the probe to the 1M Ω input port of the oscilloscope, ensuring that the input impedance of the oscilloscope is set to 1M Ω; the probe ID pin will be automatically recognized by the oscilloscope, and the attenuation ratio will be automatically set to 10:1. If it is not automatically set, it needs to be manually adjusted to the corresponding gear to ensure accurate measurement data.
Grounding connection: Connect the probe grounding wire to the grounding potential, which can only be used for grounding connection and cannot be used for other purposes; It is strictly prohibited to use non designated grounding wires to prevent measurement errors or safety risks caused by poor grounding.
（2） Calibration process
Low frequency compensation (LF Compensation): Connect the probe input to the probe compensation adjustment terminal (CAL/COMP terminal) of the oscilloscope, use the matching adjustment tool to rotate the low-frequency compensation micro adjuster, adjust the observed waveform to a standard square wave, ensure that the probe capacitance matches the oscilloscope input capacitance, and ensure measurement accuracy within the frequency range from DC to the upper limit of the bandwidth. Compensating for abnormalities (under compensation/over compensation) will cause waveform distortion and require readjustment.
HF Compensation: Calibration has been completed before leaving the factory. If adjustment is needed, a signal generator that can generate a fast rising edge rectangular wave needs to be connected. Slide the probe housing to expose the high-frequency compensation micro adjuster, and use an adjustment tool to smooth the rising edge to ensure the accuracy of high-frequency signal measurement.
DC Adjustment: Before leaving the factory, a measuring instrument with a 500VDC voltage source and a 1M Ω± 0.01% input impedance is used for calibration. Users do not need to make routine adjustments. If high-precision measurement is required, they can contact the dealer for professional calibration.
（3） Precautions for using the probe
Tip replacement: When replacing the contact tip, it is necessary to clamp the tip with pliers and pull it out vertically along the axis of the probe. It is strictly prohibited to clamp the white plastic insulator or housing (to avoid damaging the probe); When inserting the new tip, align it with the socket along the axis and gently press it until it fully fits, ensuring good contact.
Cable protection: To prevent the probe body from being impacted, excessive bending or pulling of the cable is not allowed to prevent damage or breakage of internal circuits, which may affect signal transmission.
Voltage derating: When the input signal frequency increases, the maximum input voltage of the probe will decrease. It is necessary to refer to the “Voltage derating curve” to select the appropriate input voltage to avoid overvoltage damage to the probe; Pulse measurement must comply with the corresponding limitations of peak pulse voltage, duty cycle, and duration to ensure safe use.
Maintenance and disposal
（1） Daily maintenance
Cleaning: When cleaning the probe housing, only a soft cloth dipped in water or isopropanol can be used to wipe it. After wiping, it must be completely dry before it can be used for measurement. Volatile chemicals such as benzene and diluents should not be used to prevent corrosion or deformation of the housing.
Accessory inspection: Regularly check whether the probe tip, grounding wire, and cable are intact. If the tip is worn, the cable is cracked, or the grounding wire is aged, the corresponding accessories should be replaced in a timely manner to avoid affecting measurement accuracy or causing safety hazards.
（2） Disposal of waste
When discarding probes or accessories, it is necessary to comply with the laws and regulations of the country/region where they are located and not to dispose of them at will; Components belonging to electronic waste, such as probe bodies and cables, must be disposed of in accordance with local electronic waste disposal regulations to avoid environmental pollution and comply with the EU WEEE Directive and relevant environmental requirements of each country.

（2） Core Security Guidelines
Scope of use: The device is only used for pressure equipment calibration and can measure and generate DC current/voltage, measure pressure. It is strictly prohibited to use beyond the range. If it cannot be used to measure the main power supply or belongs to measurement categories II, III, IV, the device measurement category is “Other (O)” and is only suitable for circuits that are not directly connected to the main power supply.
Environmental restrictions: The equipment protection level is IP54 and cannot be used in environments beyond this level; The working temperature range is -10~50 ℃, humidity is 20%~80% (non condensing), and the working altitude does not exceed 2000m. It belongs to Class A industrial environment products and may cause radio interference when used in residential areas. Users need to solve the interference problem by themselves.
Pressure safety: When measuring high-pressure fluids, it is necessary to use pressure resistant pipelines and connectors, check for leaks and ensure that the joints are tight. Gas measurements of 1MPa and above must comply with high-pressure gas safety regulations; It is strictly prohibited to measure flammable, explosive, toxic, corrosive fluids and high-temperature fluids/gas-liquid mixtures above 50 ℃. Gas measurement must ensure dryness and cleanliness, and avoid high humidity and high oil content air; The pressure input should not exceed the allowable range (e.g. CA700-01 allows positive pressure of 500kPa, CA700-02 is 3000kPa, CA700- * -03 is 4500kPa). Overpressure may cause equipment damage or personal injury.
Operating standards: It is strictly prohibited to dismantle the equipment casing or modify the internal structure. There is high voltage in some areas of the interior, and maintenance needs to be done by contacting the dealer; When the device is abnormal (such as smoking, odor), it is necessary to immediately turn off the power and remove the battery; Long term non use requires removal of the battery to avoid leakage and damage to the equipment; When cleaning, only use a soft cloth that has been wrung out to wipe the casing. Do not use volatile chemicals such as benzene or diluents to prevent discoloration or deformation of the casing.

Core Function Operation Guide
（1） Vertical and horizontal control
Analog signal channel configuration (CH menu)
Basic settings: Can control waveform display switch, input coupling (AC/DC/DC50), probe parameters (attenuation ratio, etc.), waveform inversion, linear scaling, label display, bandwidth limitation, offset, etc. When the input coupling is AC, low-frequency signals or low-frequency components may be attenuated, and attention should be paid to the integrity of signal monitoring; The DC50 mode displays the DC and AC components of the signal through 50 Ω.
Safety restrictions: The maximum voltage for a 1M Ω input is 300 Vrms or 400 Vpeak (100kHz and below), and for a 50 Ω input, the maximum voltage is 5 Vrms or 10 Vpeak. Overvoltage may damage the input part; When changing the input coupling, attention should be paid to the actual coupling state changes during the next waveform acquisition.
Offset cancellation: The offset cancellation function can be turned on/off through the system configuration in the UTILITY menu, and the offset setting is applicable to all input coupling modes. When the probe attenuation changes, the vertical scale will be scaled according to the new attenuation ratio. When the offset value exceeds the range, it will be automatically adjusted to the maximum value. After restoring the original vertical scale, the offset value will be restored.
Channel information copying (CH UTIL menu): The analog signal input settings of one channel can be copied to other channels by selecting the source channel and target channel. The channel ranges that can be copied for 8-channel and 4-channel models are CH1-CH8 and CH1-CH4, respectively. When copying, the source channel is light gray and cannot be selected separately. When selecting all channels collectively, although the source channel is checked, copying will not be performed.
Logic signal setting (LOGIC menu)
Basic functions: Control logic signal waveform display switch, bit setting (display switch, label, threshold level, noise suppression, etc.), bus display (switch, bit allocation, label, format, etc.), bit and bus display sequence, status display (switch, clock source, polarity, etc.), offset correction.
Collection restriction: When the record length in the ACQUIRE menu is set to the maximum value, the waveforms of LOGIC ports C (C0-C7) and D (D0-D7) cannot be collected.
Threshold and noise: The 701989 logic probe can set the threshold type (All/Each), and selecting the preset threshold will automatically configure it. After changing it, the preset will become “Userdef”; The noise suppression function is only available for probe 701989, and the level and noise suppression in the bit setting will be synchronized to the setting when the trigger source is Logic.

Note: Important information for correct device operation
As an OTDR device, AQ1000 is primarily used to detect fiber optic fault locations, monitor transmission losses, fusion losses, and other parameters. Its main functions are as follows:
1. Optical pulse measurement function
Support two core measurement modes to meet different scenario requirements:
Average Measurement
TRACE mode: After multiple measurements, take the average of the data and display the results in waveform form to improve the signal-to-noise ratio. It can detect weak events that are masked by noise, such as fusion losses and reflections.
MAP mode: After completing the average measurement, the OTDR waveform is automatically analyzed, and various events (such as fusion points and bending points) are marked with icons. If the qualified/unqualified judgment conditions are preset, the judgment results will be displayed in the color of the icon.
Key feature: Supports one-time measurement of dual wavelengths of 1310nm and 1550nm (multi wavelength measurement). During measurement, the average measurement is completed at 1310nm first, and then automatically switches to 1550nm measurement.
Real time measurement
Only supports TRACE mode, with real-time waveform updates and displays during the measurement process. It can monitor events such as fusion loss and return loss in real time, as well as observe waveform changes when parameters such as wavelength, distance range, and pulse width change.
Limitation: Cannot be performed in MAP mode, it will automatically switch to TRACE mode after starting real-time measurement.
2. Data display and analysis function
The data shows
TRACE mode: The horizontal axis represents distance and the vertical axis represents loss level, displaying the waveform of optical pulse measurement. The waveform can be scaled and moved, and detected losses or reflections (referred to as “events”) will be marked on the waveform.
MAP mode: Display all events from the measurement starting point to the fiber optic endpoint in order using icons, label the event type (such as fusion, bending, splitter) and distance from the starting point, and visually present the status of the fiber optic line.
data analysis
Waveform analysis: Measure the distance between two points, fusion loss, and return loss (inter marker return loss) through the cursor and markers.
Event analysis: Automatically detect events and display them on the screen (TRACE mode marked on the waveform, MAP mode displayed with icons), support event editing (insert/delete events, insert/delete distance reference point R), adjustable event detection conditions (such as fusion loss threshold, return loss threshold).
3. Pass/Fail Judgment
Judgment logic: Set a threshold for each measurement item. If the measurement value does not exceed the threshold, the event is judged as “Pass”, and if it exceeds the threshold, it is judged as “Fail”.
Judgment items: including connector loss, fusion loss, return loss, loss per kilometer between events (dB/km), and total loss.
The results show that in TRACE mode, qualified events have no special markings, while unqualified events are marked in red; In MAP mode, different colored icons are used to distinguish between them. The top progress bar is green when all events are qualified, and red when there are unqualified events.
4. Light source and power detection function
Stable Light Source
Transmit measurement light (continuous CW or modulated CHOP) from the OTDR port, with a wavelength consistent with the OTDR light pulse wavelength (1310nm/1550nm), for measuring optical loss or identifying optical fibers.
Visible light source (/VLS option)
Only supported by VLS option devices, emitting 650nm visible light (CW or 2Hz modulated CHOP) from the VLS port for visual inspection of fiber breakpoints and checking the core of multi-core fibers.
Power checker
Detect the presence of communication light (in use fiber) in the measured optical fiber through the OTDR port and check its power value. The supported wavelengths for measurement include 1310nm, 1490nm, 1550nm, 1625nm, and 1650nm.

Maintenance and upkeep
1. Daily inspection and cleaning
Mechanical inspection: After power failure, check the appearance of the equipment for any damage or deformation, ensure that the switches, connectors, and screws are not loose, and that the switches and moving parts operate smoothly; After powering on, check that the startup screen is normal, the buttons can switch screens, and the touch screen operation is sensitive.
Cleaning:
External device: Power off and disconnect the USB-AC adapter, wipe with a wrung out damp cloth, and avoid chemicals such as diluents, benzene, and alcohol to prevent deformation and fading.
Optical adapter and fiber end face: After turning off the power, open the light source port cover, remove the optical adapter (unscrew the M2 screw), wipe the fiber end face with a lint free and residue free lens cleaner, clean and reinstall the adapter (tightening torque of about 0.12N-m).
2. Troubleshooting and Error Handling
Common troubleshooting:
Troubleshooting and Solutions for Malfunctions
Check the USB-AC adapter connection (plug, power cord, DC plug) for no display during startup; Charge the battery and confirm that the POWER LED is on; Press and hold the power button for 2 seconds to force startup; If the backup files are damaged due to abnormal shutdown, long press the MENU button and press the power button until the device starts up
Screen automatically turns off to check battery level (low battery automatically shuts down); View power-saving mode settings (automatic sleep mode after no operation for the set time)
Touch screen unresponsive. Remove gloves and operate with bare hands; If there is still no response, restart the device or restore the factory settings
Error code handling: When the device displays an error code, refer to section 10.2 of the manual. For example, code 510 (PLUG CHECK Error) requires checking or cleaning the connector, and code 902 (low battery level) requires charging or replacing the battery; Hardware faults such as code 505-508 and 939-948 require contacting a Yokogawa dealer for repair.
