3.1 Pre-Test
3.1.1 Connect Tester
Before test, clean battery poles with metal wire brush and
alkaline detergent to avoid the tolerance caused by oil and dust
to the test result.
For Group31 or side-installed battery, install and fix the terminal
wiring connector. Otherwise, inaccurate test result will be
caused due to wrong installation or dirty or bad wiring
connectors.
W hile testing, ensure none of the in -vehicle electrical appliance
is on, doors are closed and the ignition key is in OFF status.
Connect the red test clamp with battery anode and the black on e
with cathode.
Shake the clamps back and forth to make sure they are well
connected.
The tester requires the two clamps are well connected with the
battery poles. Otherwise, the test er cannot power on. In this case,
clean the poles and re-connect it properly.
Tester has reverse connection protection function. W hen clamps are
reversely connected, tester screen will not light, but it damages
neither the tester nor the automotive load.
NOTE:
For parallel connected batteries, break off the cathode
connection first, then do single test to each battery. Suppose
cathode connection is not cut off, there will be error in test result.
