Model 8112 Instruction Manual

Model 8112 clamp adaptor is designed to be an AC current / voltage conversion probe capable of measuring

AC current from 0.1mA to 80A in conjunction with high sensitivity AC voltmeters.

It is especially useful for digital multimeters.

Simple to operate, the unit has range switch position at 200mA, 2A and 20A.
It also features safety design throughout with no exposed metal parts.

Operating Instructions:

After connecting Model 8112 to the voltmeter pull the jaw lever down to open the transformer jaws and

clamp onto a current carrying conductor.
The voltmeter reads the current measured.

Change the range switch position on Model 8112 or the voltmeter according to the current being measured.


Read the current as follows:

Model 8112 set at: AC Voltmeter set at: How to read:


200mA 200mV (e.g.) Read directly (in milliamps)

2A 200mV (e.g.) Divide reading by 100 (read in amps)


20A 200mV (e.g.) Divide reading by 10 (read in amps)
