INSULATION TESTER INSTUCTION MANUAL
1. Introduction
The digital megohmmeter uses the DC-excited transducer to convert DC 12V to DC high voltage 1000V/2500V. The main
amplifier tests the insulation voltage by the current ratio measurement of traditional megger. The input terminal uses micro-
current to test anti-interference circuit and the output terminal adopts the division function of double integrating digital
voltmeter to process the data conversion. It is characteristic of strong loading capacity, high anti-interference of electric field,
portable operation, wide range, backlight display and so on. It could also be used to test commercial electric power. With its
stable performance and high grade appearance, it is widely used to test the insulated voltage resistance for electrical equipment,
instrumentation, cables and so on.

This document describes an Insulation Tester, a digital megohmmeter designed for measuring insulated voltage resistance in electrical equipment, instrumentation, and cables.

Function Description

The device operates by converting a DC 12V input into high DC voltages of 1000V or 2500V using a DC-excited transducer. It then tests insulation voltage through a current ratio measurement method, similar to traditional meggers. The input terminal employs a micro-current anti-interference circuit, and the output terminal utilizes a double integrating digital voltmeter for data conversion. It can also be used for testing commercial electric power.
