The tester is powered by two alkaline batteries (factory installed) and
typically exhibits a life of 1,500 tests. For longer life, the user may install
commercially available lithium 9 V batteries. Lithium batteries usually
have a life of 3,000 tests depending on mAh type. As the batteries reach
the end of useful life, the peak output voltage of the tester will start to
drop and may affect the usable range. With no test device connected
to the tester, and pressing one of the TEST buttons (i.e., L1—C +), the
meter should read above 1000 V with fresh batteries. When the tester
output meter is no more than 800 V with no test device connected to the
tester, batteries should be replaced.
To replace batteries, remove the four thumb screws on the top of the
panel. Batteries can only fit in their receptacles one way, but observe how
they were oriented before removing and replacing.
The Model 4030 has a receptacle in the back that accepts the plug of the
power supply (P/N 50502-01). While the power supply is engaged,
18 V

the tester will not draw battery power.
