External DC: 11 � 16 volt.
Power consumption is approximately 2 - 3,5 watt dependent on selected modes of operation.
External DC source should have sourceimpedance less than 1 ohm and be able to supply at least 300 mA.
The mains adaptor Nor345 is recommended for use with the instrument.
If the external supply falls below 9 V, the instrument will use the internal batteries if available. If the instrument has
switched itself off due to loss of power or insufficient supply voltage, the instrument will automatically switch on and
resume normal operation after reapplying the external DC supply.
Socket for external dc:
LEMO plug type 0B with positive voltage on centre terminal.
The instrument will automatically switch off if the battery or external voltage is too low for operation within
the stated specifications.
