Operating the Probe Safely
1. You should estimate the tested voltage amplitude before testing, please do not use if
exceeds the voltage range, because it is likely the probe is damaged.
2. Connect the input lead and output lead to the probe, and then connect the probe to the
oscilloscope or other instruments.
3. Connect the power adapter to voltage probe, the power indicator light turns on green.
Please select proper range based on the tested voltage. When the tested voltage exceeds range,
the overload indicator light is on with alarming sound, which can be manually turned off.
4. Please set proper attenuation rate for the oscilloscope or other instruments according to
the probe range. And adjust the oscilloscope sensitivity based on the tested voltage.
5. Connect the probe clips based on needs, start after connecting to the circuits to be tested.
When testing, the probe body should be kept away from high voltage pulse circuits to reduce
interference to the probe.
Test Mode (Offset Setting)
Users may enter the test mode to adjust offset based on needs. The probes may be disordered
after years’ of use. The adjustment method is as follows if not at zero:
①Please press these two keys, and make short circuits for input terminals.
②Turn power on to start, entering test mode, and the overload indicator light is on,
release the two keys.
③Go into the high attenuation fact or offset adjustments under the state, press the
offset increase. Press offset decrease.
④After the adjustment, press key to switch to low attenuation ratio offset adjustment,
press key offset increases, press , offset d e c r e a s e s .
⑤Then press key to exit the test mode, offset adjustment is completed and the
overload indicator light is off, entering into normal operation mode.
Safety Notices
1. Please try to wind up the input leads when testing, this is better for eliminating noise and
to improve the ability of high frequency response. Please view below for the winding method:
