Features
Test inhibit
Test ranges extend from 10 GΩ to 200 GΩ depending on test voltage as below
Continuity (resistance) testing
Insulation resistance testing
The feedback controlled insulation test voltage is now accurate to 2% -0% compared to the original 20%, providing a more accurate test voltage without the risk of over-voltage damage to circuits.
A variable range allows the exact test voltage to be selected from 50 to 999 V in 1 V steps, (1 to 2.5 kV in 10 V steps) providing 1100 test voltage options
Variable insulation voltage
The variable mode provides a unique solution for awkward insulation voltage measurement applications. The range option allows an insulation test voltage from 50 to 999 V in 1 V steps, or 1 to 2.5 kV in 10 V steps.
Guard terminal
The guard terminal (G) is a third terminal on the connection panel. Connection of the guard terminal on certain applications provides a return path for parallel leakage currents that could otherwise create significant errors in the insulation measurement. This is especially so for surface contamination of equipment or cables.
Voltage measurement
True RMS voltage measurement to 600 V AC or DC with resolution from 0.1 mV.
Display
The display offers a combination of analogue arc and a dual digital readout:

Setup functions
Batteries
Battery requirements are 6 x AA batteries of either standard alkaline or nickel metal hydride (NiMH) rechargeable type, providing a minimum of 3000 insulation tests at 1000 V. This tester is enabled for internal charging when used with the optional charging pack (sold seperately).
Safety
Designed to be exceptionally safe to use, fast detecting circuitry prevents damage to the instruments if accidentally connected to live circuits or across phases. Specifically, all instruments:
