Key features
- Line / mains powered only (12 V DC adapter from 220 - 240 V, 50 Hz), so no batteries to replace
- Made in India
- Five test ranges: 250 V, 500 V, 1000 V, 2500 V and 5000 V
- 1 TΩ, 1.4 mA digital insulation tester with digital and analogue arc display
- Insulation (InS), Polarisation Index (PI) and variable timed test (t) modes in any test range
- User settable IR test timer (default 1 min, max. 19 min 50 s)
- Selectable DC or AC voltmeter (25 V - 600 V) with frequency
- Guard terminal to shunt surface leakage currents
- Automatic discharge of capacitive loads with decaying voltage display
- High voltage warning indicator and external voltage display after test
- Locking HV insulated plugs; shutters across the terminals keep out dirt
- CAT III 600 V safety rating
