Chapter 1 Product Summary
1.1 Product Profile
BST- 100 Battery Tester adopts currently the w orld's most advanced
conductance testing technology to easily, quickly and accurately measure the
actual cold cranking amps capability of the vehic le starting battery, healthy
state of the battery itself, and common fault of the vehic le starting system and
charging system, w hich can help maintenance personnel to find the problem
quickly and accurately, thus to achieve quick vehicle repair.
1. Test all automotive cranking lead acid battery, including ordinary lead acid
battery, A GM flat plate battery, AGM spiral battery, and Gel battery, etc.
2. Directly detect bad cell battery.
3. Polarity reverse connection protection, reverse connection w ill not damage
the tester or affect the vehicle and battery.
4. Directly test the battery w ith loss of electricity, no need to full charge before
testing.
5. Testing standards include currently the w orld's majority of battery
standards, CCA, BCI, CA, MCA, JIS, DIN, IEC, EN, SA E, GB.
6. Support multi-languages, customer can select different language package,
which includes: Chinese Simple, Chinese Traditional, English, Japanese,
Russian, Spanish, French, Italian, German, etc. Other languages can also
be customized according to user's need.
1.2 Product Function
Main functions of BST- 100 battery tester include: battery test, cranking test,
charging test and other additional functions.
Battery test is mainly targeted to analyze the battery healthy status to
calculate the actual cold cranking capability of the battery and the aging extent,
which provide reliable analysis evidence for the test and maintena nce of the
battery. It notifies the user to replace battery in advance w hen the battery
getting aged.
Cranking test is mainly to test and analyze the starting motor. Through testing
2
the actual required cranking current and cranking voltage of the starting motor,
it can find out w hether the starting motor w orks fine. There are several reasons
why the starting motor is abnormal: lubricating system fault causing the
starting loaded torque increasing or rotor friction of the starting motor causing
the increasing friction of the starting motor itself.
Charging test is to check and analyze the charging system, including
generator, r ectifier, rectifier diode, etc., thus to find out w hether the output
voltage of the generator is normal, the rectifier diode w orks fine and the
charging current is normal. Suppose one of the above mentioned parts is not in
normal situation, it w ill lead to over charge or incomplete charge of the battery,
thus the battery w ill be quic kly damaged and also greatly shorten the using life
of other loaded electrical appliance.
Additional functions include: Set language, voltmeter and screen brightness
adjustment.
