5. Operation Steps
1) Power the probe: Use standard USB-C cable to connect the differential probe to
USB port of the oscilloscope;
2) Connect to oscilloscope: Connect the BNC end of the probe to oscilloscope
channel (make sure the oscilloscope is grounded);
3) Select Range: Select appropriate voltage range according to the measured
signal;
4) Connect the DUT: Use test clips or hooks to connect the DUT, if an overvoltage
alarm occurs, disconnect the power supply and the circuit immediately;
5) Set on the oscilloscope.

4. Precautions
1) Calibrate the probe before use:
Short-circuit the input ends, power on, press “Zero” button, 5MHz LED light
flashes, after hearing a “Di” sound, means calibration succeeded; if hearing “Di
Di Di” sound, means calibration failed, needs to be calibrated again;
2) The bandwidth of the oscilloscope should be no less than the bandwidth of
the probe, channel input impedance should be 1MΩ.
3) Recommend to use after 10 mins warm-up to get more accurate result.
4) When Range LED indicator flashes and beeps rapidly, indicating Over-
voltage warning, please switch to higher range.
