POWER SUPPLY:
A 7-pin
DIN
socket accepting plug JP 0703
for
connecting external power to
the instrument
for
either direct operation
or
charging rechargeable internal
cells. The pin diagram is shown in Fig.2.5. The socket may be connected
directly to the OUTPUT socket
of
the Power Supply
ZG
0199 using the cable
AQ 0035 to provide both the operating and charging voltage (when nickel-
cadmium rechargeable cells are used),
or
to a battery charger ZG 0113
which supplies sufficient power to run the instrument via the internal rechar-
geable cells, where fitted, and keep them charged. For further details on
powering the instrument, see Section
