- Overview
- Specifications
- Summary
Product Highlights
- Performs safe and accurate field measurement of winding resistance
- Designed for smaller transmission and distribution transformers
- 2 channels with max 6 A current output
- ±0.25% measurement accuracy
- 48 V test voltage for fast saturation of transformers
- Adjustable output current enables user to select from five current ranges
- Multimeter type operation is intuitive and fast
- Minimal number of controls — single selector switch for test current, single button to activate test cycle
- Safety ensured through automatic, passive discharge circuitry
- Continuous operation with very short start-up time
- Compact size and low weight for true portability
- Rugged plastic case rated to IP67 when closed
- Test leads fitted with Kelvin clamps for single, one-time connection to unit under test
- 33 ft. test lead length allows easy testing of pole mounted transformers
