Digital Insulation Tester is designed for elevator maintenance and features 2 test voltage ranges - DC15V or 500V.
The Sanwa M53 is a digital insulation resistance tester, with DCV & ACV measurement functions. In addition to that, it has an optional speed measurement function (requires: Sanwa Speedometer SE-9100) that enables the unit to read output voltage directly as a speed value.
The M53 has two test voltage ranges, 500 Volts DC and 15 volts DC. It has a measurement accuracy of ± (2 % reading + 2 digit) when measuring insulation resistance. The analog to digital converter in this device uses the double-integration method and has a sample rate of 2.5 samples per second.
