iBT100 12 Volt Automotive Battery Analyzer User’s Guide - English Version_V2.00

Tester starts the charging volt test after RPM increase is detected.
After the test finished, tester displays the effective charging volts, ripple test result and charging
test result.
NOTE:
If RPM is not increased, it shall be the fault of generator regulator or connection with battery failed.
Tester will try 3 times to further detect, if still failed, it will skip the increase rev detect and the test
result displays "No Volt Output". Check the connection between generator and battery, then retest.
Charging Test Result:
a. Charging Volt: Normal. The generator output normal, no problem detected.
b. Charging Volt: Low. Check drive belt of the generator whether slip or running off. Check the
connection between generator and battery is normal or not. If both of the drive belt and the
connection are in good condition, follow the manufacturer's suggestion to eliminate generator fault.
c. Charging Volt: High. Since most of the vehicle generators are using internal regulator, the
generator assembly has to be replaced.(Some old style cars are using external regulator, then
directly replace the regulator.) The normal high volt of the voltage regulator is maximum 14.7
±
0.5V.If charging volt is too high, it will overcharge the battery. Therefore, the battery life will be
shortened and troubles will be caused.
