Project Description

AMPROBE (AMC-3 Hand-Cranked Insulation Tester)

• 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
• Light and smooth operating crank
• Rugged cross coil movement
• High impact housing
• Spring loaded terminal connection

Insulation Resistance with 500VDC Test Voltage:     N/A
Insulation Resistance with 1000VDC Test Voltage:     “0-500MΩ ±5% Rdg @ (0.1 – 100MΩ)** 
±10% Rdg @ > 200MΩ**”
Low resistance:     0-200Ω ±10% Rdg**
