Operation and setting5.5.2 Adaptation to the system leakage capacitance (Cemax : 150 µF)This menu allows to adapt the A-ISOMETER® to the maximum system leakagecapacitance (max. 500 µF). Please note that the basic measuring time willbe increased to approximately 10 seconds when the setting is C e = 500 µF.Factory setting = 150 µF.5.5.3 Changing the measuring principle from AMP to DC (Measure: AMP)The DC measuring principle is only suitable for pure AC systems.Factory setting = AMP.5.5.4 Setting the repetition time for automatic self tests (Autotest: 24h)The time for the repetition of automatic self tests can either be set to 1 houror to 24 hours or can be deactivated.Factory setting = 24 h5.5.5 Setting the real-time clock (Clock) (IRDH375B)The setting of the real-time clock is the time base for the memory and for theautomatic self test. In case of failure of the supply voltage, the real-time clockkeeps running for approximately 30 days. When the device will be switchedon after this period, a flashing "C" appears on the display and the clock hasto be set again.5.5.6 Setting the date (Date) (IRDH375B)As well as the time, the date is required for the memory, too. In the event ofpower supply failure, the date function is not influenced for at least 30 days.If the device is switched on again after this period, a new setting of date andtime of the real-time clock is required.5.5.7 Specifying the starting time of the automatic self test (Test) (IRDH375B)If the 24h self test is activated in the ISO ADVANCED menu, it is possible toset the time (hour) when the self test is to be carried out by means of the"TEST: 12:00" sub menu. Then the self test is automatically carried out oncea day at a given time. If the 1 hour auto test has been selected, the self testwill be carried out at every full hour.46 TGH1352en/11.2004
