1.3 Ground Wire Monitoring
For checking the basic isolation of the heater, the calibrator is
equipped with a ground wire monitor. The monitoring unit operates
independently of the other controller components and switches off
the power supply of the heater as soon as the calibrator loses the
connection to the ground wire system of the isolation. Once the
connection to the ground wire system has been re-established, the
monitoring unit automatically reconnects the heating circuit to the
power system.
