Battery Test
Automatic display of “
when battery voltage
falls to below approx. 2.3 V.
Battery Saver Circuit
The instrument switches itself off automatically if the measure-
ment value remains unchanged for about 10 minutes, and if
none of the operating elements are activated during this time.
This function is disabled in the transmission and menu modes,
or if “continuous on” has been activated.
Fuses
The current measuring ranges are protected by an internal
250 mA fusible link. A defective fuse can only be replaced by
GMC-I Service GmbH service personnel.
The voltage of the measuring current circuit may not exceed
600 V
