(3) Connect Probe
Take the probe found in the attachment and connect its BNC header to the BNC terminal of the oscilloscope.
Connect the probe’s main alligator clip to the "Calibration terminal" and the ground clip is connected to the
“Ground terminal” shown below. The output of the sensor should be a 3V
p-p
square wave, with a 1 kHz
frequency.
Calibration and Ground Terminal
(4) Function Check
Press the AUTO key, a 3V
p-p
1 kHz square wave should appear. Repeat step 3 for all channels. If the output is
not a square wave with the above descriptions, please perform the probe compensation step in the next
section.
(5) Probe Compensation
When the probe is connected to any input channel for the first time, this step might be required in order to
match the probe and the input channel. Please follow the following steps:
①
Set the attenuation coefficient in the probe menu and the switch on the probe to 10x, and connect the
probe to CH1. Make sure the probe’s connector is properly connected with the oscilloscope. Connect
the probe’s main clip and ground clip to the oscilloscope’s calibration and ground terminal respectively.
Open CH1 and press the AUTO button.

②
If the displayed waveform does not look like the above “correct compensation” waveform, use a
non-metallic screwdriver to adjust the probe’s variable capacitance until the display matches the
"correct compensation" waveform.
Warning: To avoid electric shock when measuring high voltage using the probe, please ensure that the
probe insulation is in good condition and avoid physical contact with any metallic part of the probe.
