1/ PRESENTATION

The PAC 21 current clamp measures DC or AC currents, without opening the circuit they are
flowing in. The current clamp is used as an accessory for multimeters, recorders.
This clamp measures DC currents up to 1400 A and AC currents up to 1000 A. It outputs the
form and amplitude of the current measured as a voltage image of the primary current.
The PAC 21 has two ranges, 1 mV/A and 10 mV/A, a zero adjust push button, auto off feature
to economise the battery power supply and two light indicators, one for faults (over-range /
incorrect zero reset), the other for power supply.
