strip (if there is) completely then begin next battery test. We can select any way to test
different poles of one battery but please make sure all battery direction are same. After
testing one battery pole, if we select “test connection strip” test the connection strip then
begin next test on battery pole.
2.2.4 Test connection strip (before testing strip please test pole)
a. When we select “test connection strip” please add the line according to above
diagram.
