Chapter 1 Product Summary
1.1 Product Profile
BST-460 Battery Tester adopts the state-of-the-art conductance testing
technology in the world to easily, quickly and accurately measure the actual
cold cranking amps capability of the vehicle starting battery, healthy state of
the battery itself, and common fault of the vehicle starting system and charging
system, which 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, AGM flat plate battery, AGM spiral battery, and Gel battery, etc.
2. Directly detect bad cell battery.
3. Feature reverse polarity protection: reverse connection may not damage
the tester or affect the vehicle and battery.
4. Directly test the battery with loss of electricity, full charge is not required
before testing.
5. Testing standards cover the majority of world's battery standards, such as
CCA, BCI, CA, MCA, JIS, DIN, IEC, EN, SAE and 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
BST-760 battery tester features the following functions: battery test, cranking
test, charging test and other additional functions.
Battery test mainly aims 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 maintenance of the battery.
It may notify the user to replace battery in advance when the battery gets
aged.

Cranking test is used to test and analyze the starting motor. Testing the actual
required cranking current and cranking voltage of the starting motor is helpful
to determine whether the starting motor works properly or not. If the starting
motor runs improperly, find the possible reasons: lubricating system
malfunction may cause an increased starting loaded torque; or rotor friction of
the starting motor generates an increasing friction of the starting motor itself.
Charging test is to check and analyze the charging system, including
generator, rectifier, rectifier diode, etc., thus to find out whether the output
voltage of the generator is normal, the rectifier diode works properly and the
charging current is normal. In case one of the above mentioned parts is
abnormal, it will lead to over charge or incomplete charge of the battery, thus
cause quick damage to the battery and greatly shorten the life of other loaded
appliance.
Additional functions include: Set language, Set voltmeter and screen
brightness adjustment.

Chapter 3 Operation
3.1 Pre-Test
3.1.1 Connect Tester
Before test, clean battery poles with metal wire brush and
alkaline detergent to avoid the tolerance caused by oil and dust
to the test result.
For Group31 or side-installed battery, install and fix the terminal
wiring connector. Otherwise, inaccurate test result will be
caused due to wrong installation or dirty or bad wiring
connectors.
While testing, ensure none of the in-vehicle electrical appliance
is on, doors are closed and the ignition key is in OFF status.
Connect the red test clamp with battery anode and the black one
with cathode.
Shake the clamps back and forth to make sure they are well
connected.
The tester requires the two clamps are well connected with the
battery poles. Otherwise, the tester cannot power on. In this case,
clean the poles and re-connect it properly.
Tester has reverse connection protection function. When clamps are
reversely connected, tester screen will not light, but it damages
neither the tester nor the automotive load.
NOTE: For parallel connected batteries, break off the cathode
connection first, then do single test to each battery. Suppose
cathode connection is not cut off, there will be error in test result.

3.2 Tester Startup
The tester automatically starts up after the clamps are correctly
connected, and displays the Launch startup interface (Default
voltmeter is ON) refer to figure 1.
Figure 1, Startup Interface with Voltmeter on
By default, the voltmeter value at the middle bottom of the startup
interface can be used as DC voltmeter. The measurement range of
DC Voltmeter is 8-30DCV, out of which will damage the tester.
Voltmeter function can be set as "OPEN/CLOSE" in “Set voltmeter”
under Additional Functions.
If Voltmeter is OPEN and no activities are made on the tester after
startup, the screen will remain as the startup interface all the time. In
this case, it can be used as a DC Voltmeter. When OK key is pressed,
tester enters the battery test program. Press MENU key, it enters
additional function program.
When Voltmeter is OFF, the startup interface will display as figure 2.
After 2 seconds, it automatically enters the battery test program.
Press MENU key within this 2 seconds, it enters additional function
program.

NOTE: While the system prompts you to start engine, pressing
RETURN key can not exit the current interface.
Follow the on-screen instructions to start the engine, the tester will
automatically complete the cranking test and display the result.
Generally, cranking voltage lower than 9.6V is regarded as abnormal
and it is OK if it is higher than 9.6V.
Test result of the tester includes actual cranking voltage, cranking
amps, and actual cranking time.
When cranking test is abnormal, battery test result will be displayed.
See below picture:

For ripple test, the tester will present the real time waveform and
ripple volt and charging volt values are displayed at the bottom line.
It takes approx. 6 seconds for the ripple test.
After the ripple test, the tester will automatically start the loaded
voltage test. See below picture:
Loaded Volt Test takes approx. 3 seconds, and then the "INCREASE
REV" prompt will appear on the screen. See below picture:
