The Amprobe AMC-3 hand cranked insulation tester allows the user to test insulation of wires, cables, transformers and electrical motors. The AMC3 does not require batteries or any external power supply, making the tester always ready to use.
The Amprobe AMC-3 features a sensitive ohmmeter for checking resistance of motor windings and a gaurd terminal which eliminates surface leakage that may influence readings. With the AMC2 hand-cranked tool, you are always ready to test..
Features:
Insulation resistance with 1000 V DC test voltage: 0 Ω - 500 MΩ
Low resistance (300 mV DC): 0 Ω - 200 Ω
Tests insulation of wires, cables, transformers and electrical motors
The test voltage is obtained by means of a hand cranked, constant voltage generator
Does not require batteries or any external power supply, always ready for use
Sensitive ohmmeter for checking resistance of motor windings
Guard terminal eliminates effect of any surface leakage that may influence readings
