2.2 Wiring instruction
2.2.1 Wiring Notices:
During test please don’t put test clip on bolts cap to avoid affecting test accuracy but
can put it on pole bar or connection strip.
If we can’t clip the test clips please turn to test pin (option part).
Battery reference internal resistance please refer to information from manufacturer. If
no supplied information please refer to instrument one. It will affect evaluation.
Confirming test mode. Before test line connecting battery please confirm test mode
firstly to ensure whole process smooth.

2.2.3 Test battery pole
When we test one group battery please test one battery all poles and connection
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.

b. Before it is going to testing a battery bank, it has to finish all testing of poles and
connectors of one battery, then start to testing next battery. First, test the poles, and
then test the connectors. When
finished testing of all poles and connectors of one battery, test the next cell battery
poles and connectors as the same direction.
III.Operation Rules
3.1 Fast test procedure
First step:：Press power button long time and release it until enter into
interface .
Second step：setting：main interface “ ” —“ ”, enter into new
battery parameters setting interface.
Fig 3.1 Set test specification
Set machine room, technician, battery number
Set battery quantity (need the test battery quantity)
Battery manufacture selection:
1) Select “USER” then set single battery voltage, volume, reference internal
resistance according to battery specification.
2) If select other battery manufacturer then set these specification via menu.
Minimum voltage setting. During test if voltage is lower than this level device will
send alarm but won’t affect test.
Test mode: By manual or automatic
1) If manual test each change on test clip will request us to click “Start test” for next

6
test.
2) If automatic test every time change on test clip the instrument will test
automatically don’t need manual click.
Pole quantity setting. According to poles quantity to set.
Test mode:
1) Test the connection strip resistance.
2) Select “test connection strip” If don’t test select “test on pole”.
Test item:
1) Test voltage and internal resistance together.
2) Just test voltage no internal resistance.
3) Test all voltage firstly then test internal resistance.
It’s unnecessary to set float charging voltage, current, temperature won’t affect test.
Third step：Finish setting. Connect instrument and test line. Clip the test clips on
battery (pay attention on pole. Red is positive and black is negative) Click “Start test”
Click “Yes”.
Forth step: test process
After finishing test of first battery, remove test clip to next battery( firstly remove test
clip on the negative pole and then remove test clip on the positive pole ; Or remove
two clips simultaneously ).
Oper Mode:
1. “ Manual”, click “Start “ test next battery .
2. “ Auto” the instrument test automatically after 1-2s , user don’t click “ start “ .
Fig.3.1-1 Start test
Fifth step: end of test: Finish the test. Click “Return” to the main interface. If the

7
whole battery group test was not finished when return but want to go on test click “Test
battery” the test will be continued as per last test.
Sixth step: data check : “Data Mgmt” Select certain files and click “View” We’ll find
detail data.
Seventh step: Generation of report: Print test report. External storage. SD card
can transfer data to computer by card reader. Just open the software in the computer
will be ok. If it’s internal storage click “Data Mgmt” and click “Exp ALL” the data will be
transferred to SD card. Then repeat first operation we’ll read all information.
