Slide the sliding switch on the card slot upper cover backward, open the test card slot upper cover, put the
test conductor into the test card slot, push the sliding switch and close the card slot upper cover. The test
conductor shall be not powered on in this process.

）
Power on the conductor, adjust the oscilloscope settings as needed, and read the measurement result. When
the measurement result is positive, it means that the current flowing through the conductor is in the same
direction as the arrow indicated on the upper cover of the test card slot.

）
After the test is completed, disconnect the conductor power supply and then take out the conductor from the
card slot.
Tips for use of AP202 current probe:
1
）
When it is necessary to measure the differential current waveforms of two conductors, the two conductors
can be simultaneously inserted into the test card slot in the opposite direction of the current for measurement.
2
）
When it is necessary to measure the superimposed current waveforms of two conductors, the two conductors
can be parallelly inserted into the test card slot in the same current direction for measurement.
3
）
When it is necessary to increase the sensitivity due to small test current, the wires can be winded for a few
turns before passing through the card slot. The measured reading is divided by the number of wires passing
through the card slot to obtain the desired result.

Warning:
The maximum input voltage of the AP202 current probe is 20A (DC+ACpk). Do
not exceed this voltage in use. Otherwise, it will cause personal hazard or injury
or damage to the DUTs.
