3.3 Electrical Connection
The unit must be switched-off. Connect the spiral cable of your VD84 to the
socket of the sensor head VSP521 or VSP522.
Battery operation
Before operating the VD84M a suitable battery or rechargable accu must be
inserted.
Therefore, pull the battery cover on the back of the unit downwards, connect the
battery to the cable plug and close the cover again by pushing it upwards until it
snaps into position.
Battery types:
-
9V AlMn block battery type 6LR 61; lifetime max. 40h
-

Operation with external mains adapter
Alternatively to battery operation the VD84 can be supplied by an external plug-
in mains adapter (12V).
When using an external mains adapter, there must not be a
battery connected inside the instrument. The arising charging
current may lead to destruction of the battery and damage your
health by leaking battery acid.
