Tips for use of AP204A 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 40A (DC+ACpk). Do
not exceed this voltage in use. Otherwise, it will cause personal hazard or injury
or damage to the DUTs.

16.15 AP622 Current Probe
The AP622 current probe is a cost-effective, common current probe that can measure DC and AC at the same time.
Its measuring current ranges from 50mA to 60A peak and the bandwidth is up to 100kHz. It provides two ranges
(10A and 100A) for easy switching between low and high current measurements. The probe has a power indicator
and an overload indicator and is battery powered for easy measurement. The option can be purchased by users.
The option number is 4456-H07.
