4.1 Fast Testing
4.1.1 The cell voltage function is default instrument settings, can’t be choose,
4.1.2 Other test functions can choose. Once it be chosen , the tester will test it; otherwise it won’t. So users can choose the test items as they need.
4.1.3 Users can adjust all the functional parameters by pressing the numeric pad. (set the upper limit and lower limit as they need).
4.1.4 If the test result within our presetting range,it will indicate”Pass”.
4.1.5 If the test result beyond our presetting range,it will indicate”NG",
In the display of “NG”,the character’s background color will be deepened., meanwhile will make a beep.

4.2 Capacity Testing
4.2.1 The charging current can set;
4.2.2 The discharging current can set;
4.2.3 The charge cut-off voltage can set;
4.2.4 The discharge cut-off voltage can set;
4.2.5 After the capacity test completed, cell voltage,test time and the capacity will displayed on this screen.
