face of the electronic case. On the upper side panel is a
1.6mm DC power socket for connection to an external 9-
12V supply.
2.3. Power sources
The UPM is powered by a standard 9V battery housed
within the meter unit. Rechargeable batteries (Ni-MH or
similar) can be used in the UPM.
Alternatively one can use an external 9-12V DC power
supply to power the unit. When such a supply is used the
front panel pushbutton is disabled and the UPM will run
continuously. Note that the external DC supply will not
charge any battery fitted at the time even if it is a
rechargeable type.
