This earth fault detection ISOLTEST Medical series was designed for operating theatres for continuous monitoring of insulation resistance to earth, systems connected to 1-Ph and 3-Ph networks up to 500 V with neutral insulated from earth downstream of the insulation transformer.

When the insulation resistance falls below the specified value (expressed in kohm), the earth fault detection ISOLTEST Medical series cuts in, activating an acoustic signal and an optical indicator. Calibration is handled by a potentiometer located on the front enabling control between 50 kohm and 150 kohm; a green LED (NORMAL) indicates the insulation status, a red LED (ALARM) indicates fault status. There are also two push-buttons for TEST and RESET.

Remote optical and acoustic indicators can be connected to the terminal block, together with the routine check buttons for test and reset.
