Fixed Value Insulation Tester/Megger Calibration System

Type: 9409 FV

has designed a Fixed Value Insulation Tester Calibration System 9409 FV which can suitably used for the purpose of calibration and testing of insulation testers and megohm meters with impressed test voltages upto 10kV. This instrument can be custom made with single point fixed high resistance values anywhere between 1k Ohm to 10 T Ohm. The fixed point values can be selected by the customer. Units can be made with as few as three values and as many as eleven resistance values.

Function:Calibration Resistance Standard
