The instruments are powered either continuously from the mains, via a power supply, or from the
internal 6V rechargeable battery. The battery provides more than 12 hours continuous use. It can
be recharged at 12V, either from the mains or from a vehicle battery. Recharging is completed in
5 hours and overcharging is virtually impossible. The 12V (6-18V DC) external power supply inlet
is protected against incorrect polarity supplies.
A charge indicator on the front panel is illuminated when the external supply is connected.
Note:
If the instrument is to be powered continuously from the mains supply, for example
where it is to be built into a larger system, the internal battery will not be required. The
battery can be taken out of service by disconnecting it.
Caution:
Care must be taken when disconnecting the battery, if unsure please ask a
qualified service person or seek advice from Bartington Instruments.
Disconnect the battery in the following way:
