The GR8-1200 battery analyzer and diagnostic
charger will determine the internal condition of a
battery before attempting to apply a charge to it.
The charger applies an AC signal at a known frequency across
the terminals and measures the internal conductance to
determine battery health before attempting to charge.
NOTE
:
When you start a new test, the last test
results in memory are overwritten. Remember
to record or print the results if you need to retain
them.
