METRACALMC
Multimeter, Calibrator
LCD Test All display segments available during
operation of the METRACAL MC are acti-
vated after the instrument is switched on.
Power Supply
Battery 2 ea. 1.5 V mignon cell (AA),
alkaline manganese per IEC LR6
or equivalent rechargeable battery
Service life With alkaline manganese (2600 mAh)
If voltage drops below 1.8 V, the
instrument is switched off automatically.
Battery test Battery capacity display with battery
symbol in 4 segments: “ ”. Querying of
momentary battery voltage via menu
function.
Mains Power With NA X-TRA power pack
Power Saving Circuit
The device is switched off automatically if the measured value
remains unchanged for a long period of time, and if none of the
controls are activated before a selected period of time in minutes
elapses. In the case of the simulator, the output is switched off
first, followed by the display one minute later, if no controls have
been activated.
Automatic shutdown can be deactivated (APoFF = ON).
