1/ PRESENTATION

The PAC 20 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 20 has one range, 1000 A (sensitivy 1 mV/A), a zero
adjust rotative button, and one light indicator for power supply.
