Operation

The BAT 171 is supplied with power from the 12 V
battery to be tested or from the internal batteries. The
BAT 171 is provided with protection against incorrect
polarity, overvoltage and overheating.

Preparation

Before connecting the BAT 171, use a wire brush and a
mixture of natron and water to clean the battery posts.
For testing 12 V batteries with side posts, attach and
secure post adapters.
!
Never use steel screws as measurement points. The
test results may be biased if no post adapters are
attached or use is made of worn or contaminated
post adapters. To prevent damage, the post adapters
are not to be tightened by more than a quarter turn
using a wrench.
