with 20 s on-time
and one measurement each with a duration of 5 s
– with one set of batteries (alkaline-manganese):
1,600 measurements
– with one set of storage batteries (2200 mAh):
1,000 measurements
Safety Shutdown The instrument is switched off, or cannot be
switched on, if supply voltage has dropped to
below the critical level.
Charging Socket
Inserted rechargeable batteries can be recharged
inside the instrument by connecting the NA102
battery charger (Z501N) to the charging socket.
