Power Supply
Battery 2 AA size batteries,
alkaline manganese per IEC LR6
(2 ea. 1.2 V NiMH rechargeable battery
also possible)
Service life With alkaline manganese (2600 mAh)
If voltage drops below 1.8 V, the
instrument is switched off automatically.
Battery Indicator Battery capacity display with battery
symbol in 4 segments: .
Querying of momentary battery voltage via
menu function.
Power Saving Circuit
The device is switched off automatically if none of the controls are
activated for a period of approximately 10 minutes. The simulator
is switched off after a period of only 5 minutes (sockets are cur-
rent and voltage-free). Automatic shutdown can be deactivated.
Power pack socket
If the NA X-TRA power pack is plugged in,
the installed batteries are disconnected
automatically.
Rechargeable batteries can only be
recharged externally.
