Multifunction Insulation Tester

Model: 92788

This is a product which has everything you'll ever wanted in a compact size tester.
It has all the basic features needed to check and certify an electrical installation.
It has a MOV test feature which is used to test and certify protection devices. This is used on Mains protection devices as well as telecom devices. The MOVs can be tested up to 1000Vdc.
It has the facility to measure insulation versus time, like using the Dielectric Absorption Ratio and the Polarization Index. These 2 features are very useful for scheduling predictive maintenance.
This model is preferred by Plant Maintenance Technicians.

Features:
● Auto-Range microprocessor controlled.
● Insulation test voltages : 250, 500, 1000V
● Polarization Index test.
● Dielectric Absorption Ratio test.
● Mov/protection devices test.
● Gas Arrester function.
● Automatic voltmeter AC/DC at Start/Reset.
● Test ON-OFF.
● Battery test.
● Safety voltmeter before each test.
● Auto-Discharge on all test and all ranges.
● Leads Auto-Null key.
● Test Auto-Stop.
● Smart hold & Stop on voltmeter ac/dc.
● Ener-SaveTM.
● EN 61010-1 / EN 61326-1 / CAT III 600V.
