Fig. 16.34 Diagram Accessories of AP621 Probe
The AP621 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.
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
）
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.
5
）
After the test is completed, take out the conductor from the card slot.
Warning:
The maximum input voltage of the AP621 probe is 2000V (DC+ACpk). Do not
exceed this voltage in use. Otherwise, it will cause personal hazard or injury or
damage to the DUTs.
