The Battery Error Preventing System (BEPS) recognizes batteries levels
as they become weaker.
To prolong battery life, the backlight and printing features are dis-
abled when the batteries are getting low; "LOBAT" indication is displayed
on LCD to warn the user of this condition. However, the meter contin-
ues to measure correctly even when the low battery indication is
displayed. The meter automatically switches itself off when the batter-
ies are too weak to support proper function.
The meters are equipped with an internal lithium battery that powers
the clock circuit even in the absence of power supplies.
For long term field and lab applications, these meters can be connected
to a 12VDC adapter.
