MT-5030 Digital Insulation Tester

User’s 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 digit al
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.
