Instrument Positioning; Power Supply; Operation With Charger/Power Adaptor - GE USM 36 Series Technical Reference And Operating Manual

3 Initial start-up

3.1 Instrument positioning

Fold out the prop-up stand on the rear side of the
USM 36 and position the instrument on a flat base so
that you can easily read the display.
If the instrument has been moved from a cold room into
a warmer one, wait until it has adapted to the room tem-
perature before you power it on (to avoid condensation).
If (in rare cases) condensation has developed inside the
instrument, the cover may mist up from the inside. In this
case, open the cover until the damp has dried up. You
should not power the instrument on until this has hap-
pened.

3.2 Power supply

The USM 36 can be operated either with an external
charger/power adaptor or with the corresponding lithi-
um-ion battery.
You can also connect the USM 36 to the mains power
supply if the battery is in the instrument. A discharged
battery is charged in this case, during the instrument op-
eration.

Operation with charger/power adaptor

Connection to power supply
For the operation using a charger/power adaptor, you
should only use the charger/power adaptor included in
the standard package.
The charger/power adaptor is automatically adjusted to
every AC voltage between 90 V and 240 V (nominal
voltage).
