Specification

Test Voltages 50V/ 100V/ 250V/ 500V/ 1000V

Test voltages from 50V to 1000V can be selected for Insulation Resistance measurement. It covers all insulation tests up to 1000V.

Insulation Resistance Measurement

The instrument is capable of measuring insulation resistance from 10 KOhm …999 MOhm.

Hands-free continuity testing

Continuity testing (0-10 with acoustic signal) can be done without pressing the test button. In addition to the display function, an acoustic signal can be activated which sounds if the adjustable limit value is violated.

Voltmeter

Instrument measures voltages > 25V … 600 V AC/DC.

Automatic discharge for capacitive circuits after test Measurement

Capacitive devices under test, such as cables and windings that get charged during the test are discharged by the tester.

Live circuit detection

Displays presence of voltages > 25V irrespective of function selected.

Pre-selectable measurement time for Insulation Resistance Measurement

In normal course, the insulation test terminates and the measured insulation resistance value remains on display for 2 sec after the test key is released. With the Pre-selectable measurement time feature, the insulation test continues and the measured value remains on the display for the pre-determined time. Pre-selectable time: 10 sec – 5 min.

Pre-selectable limit checks (Go/ No-go option) for MOhm

An acoustic signal can be generated when the measured value of insulation resistance falls below an adjustable limit value.

Lead resistance null facility

The instrument provides a facility to compensate the resistance of the leads for an accurate measurement of low resistance.

Storage of MIN/MAX values

In addition to the display of the actual measured value, the minimum or maximum value can constantly be updated or stored.

Storage Memory for last 50 readings

The instrument provides a facility to store and recall 10 values in each of the 5 ranges of insulation resistance measurement.

Blown fuse indication

The display FUSE points to a blown fuse.

Stop Watch

This function allows you to measure elapsed time up to 1 hour.

Auto-power off function

The instrument turns off automatically, if any of the keys or the instrument turns off automatically, if any of the keys or the selector switch have not been activated for about 10 minutes in insulation range and 5 minutes in other ranges or can be switched to continuous operation.

Protective holster for rough duty

A holster of soft rubber with tilt stand protects the meter against damage in the case of shock and drop.

Low Resistances Measurement (0.01Ohm… 99.9 Ohm)

Low resistances can be measured up to 99.9Ohm. There are two measuring ranges for Low W: 9.99Ohm and 99.9Ohm.
