The AP622 current probe is easy to use, but users who are not familiar with this product should read this manual
completely before starting the operation:
1
）
Push the switch to the appropriate range position according to the measured current. The power indicator
turns green and the overload indicator does not light up.
2
）
Connect the BNC plug to the oscilloscope.
3
）
Oscilloscope setting: Set the oscilloscope
’
s impedance to 1M
Ω
, set the coupling mode to DC, and select the
appropriate oscilloscope range according to the measured current.
4
）
Zero adjustment: Zero adjustment is required before each test. Turn the zero adjustment knob of the current
probe to set the display value on the oscilloscope to zero.
5
）
Measurement: Open the clamp and pass the tested wire through the center of the jaw. Note that the diameter
of the tested wire cannot exceed the size of the jaw. When the measurement range is exceeded, the overload
indicator will light up. Select the appropriate range and repeat the zero adjustment measurement.
6
）
After the test is completed, disconnect the conductor power supply and then take out the conductor from the
card slot.
