Powering up your Presidium Duo Tester II
This tester can be powered either by the use of an AC
adaptor or through the use of batteries. If AC adaptor is
used, connect one end of the AC adaptor to the tester and
the other end directly into a suitable electrical outlet. Please
ensure that only the adaptor supplied by Presidium is used.
If batteries are used (5 x AA batteries), take note of the
positive (+) and negative (-) directions of batteries when
inserting the batteries into the tester
(Fig. 1.1).
The use of
alkaline batteries is preferred, as it should generally give
approximately eight hours of continuous operation, while
the use of ordinary batteries will give a shorter working life.
