1. GETTING STARTED with your Presidium Carat
Scale
Powering up your Presidium Carat Scale
This scale can be powered by either the use of an USB
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
(Fig. 1.1).
If batteries are used (4 x AAA batteries), take note of the
positive (+) and negative (-) directions of batteries when
inserting the batteries into the scale
(Fig. 1.2).
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.
