Chapter 3 Operation
3.1 Pre-Test
3.1.1 Connect Tester
Shake the clamps back and forth to make sure they are well
connected. Tester requires the two clamps are well connected with
the battery poles, otherwise, the test cannot go on. When enter the
battery test program, screen prompts "Check Connection", do clean
the poles and re-connect in the right way.
Tester has reverse connection protection function. When 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.
