1. GETTING STARTED with your Presidium Duo Tester
Powering up your Presidium Duo Tester
This tester can be powered either by the use of an AC
adaptor (optional item sold separately) 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 two and a half hours of continuous
operation, while the use of ordinary batteries will give a
shorter working life.

socket before turning on the unit. Otherwise, the indicator
