Chapter 1 Product Summary
1.1 Product Profile
MICRO-768 Battery Tester adopts currently the world's most advanced conductance
testing technology 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.

affect the vehicle and battery.
4. Directly test the battery with loss of electricity, no need to full charge before testing.
5. Testing standards include currently the world's majority of battery standards, CCA, BCI,
CA, MCA, JIS, DIN, IEC, EN, SAE, 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 MICRO-768 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 maintenance of the battery.It notifies the user to replace
battery in advance when the battery is getting aged.
Cranking test is mainly to test and analyze the starting motor. Through testing the
actual required cranking current and cranking voltage of the starting motor, it can find out
whether the starting motor works 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,
rectifier, rectifier diode, etc., thus to find out whether the output voltage of the generator is
normal, the rectifier diode works fine and the charging current is normal.Suppose one of the
above mentioned parts is not in normal situation, it will lead to over charge or incomplete
charge of the battery, thus the battery will be quickly damaged and also greatly shorten the
using life of other loaded electrical appliance.
Additional functions include:
View test result, print test result, voltmeter, ammeter, thermometer and temperature
compensation, thermometer unit choice, QC mode, client code setting, set language, set
date and time format, date and time adjustment, set user info, screen light adjustment, set
printer definition, standby power function.

Chapter 3 Operation
3.1 Pre-Test
3.1.1 Connect Tester
Before test, clean battery poles with metal wire brush and alkaline cleaner to
avoid the tolerance caused by oil and dust to the test result.
For Group31 or side-installed battery, connect 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 test clamp with
cathode.
Shake the clamps back and forth to make sure they are well connected.
Tester requires the two clamps are well connected with the battery poles,
otherwise, the test cannot go on. When enter the battery test program, screen
prompts "Check Connection" (See below picture).Do clean the poles and
re-connect in the right way.

Tester has reverse connection protection function. When clamps are reversely
connected, tester will prompt "Reverse Connection" (See below picture), 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.
3.1.2 Key Description
●Up and Down keys
Select upwards or downwards via white UP and DOWN keys.
● Return key
Return to previous menu via blue RETURN key.
●OK key
Confirm the selection via green OK key
●MENU key
Enter additional function program via MENU key.
●Power key
Turn on/off the tester.(Refer to 3.2 Tester Startup)
3.1.3 Connect Current Clamp
To test cranking amps and charging current, first connect the current clamp before
startup, then turn on the current clamp power swtich.
After tester startup, current clamp is able to work.

Press the reset key of the current clamp and connect the current clamp jaw to the anode
wiring between the battery to be tested and the generator. See below picture.
As the minimum width of the current clamp jaw is only 28mm, choose the connection
cable or connection pole with diameter less than 28mm to test. Otherwise, the current
clamp jaw cannot close completely.
NOTE: 1. Current clamp jaw must close to avoid test tolerance.
2. Current clamp uses 9V alkaline battery. Turn the clamp power off after
using the current clamp.
3. Before testing the current, take off the current clamp from the battery
positive connection cable, and reset.
3.2 Tester Startup
Tester will start up after pressing the power key, and display the customized
logo interface (Default voltmeter is ON) refer to figure 1.
Figure 1, Startup Interface with Voltmeter On

Lancol MICRO-768 Battery Tester User Manual

At the bottom left of the startup interface, " " shows the real time capacity of the internal
9V battery. When the capacity of the 9V battery is not sufficient, do replace it in time to avoid
effect to the usage of the additional functions.
By default, at the middle bottom of the startup interface, it displays the
voltmeter value, which can be used as DC voltmeter.DC voltmeter measure range is
1.0-30VDC.(Caution: Over this measure range, it will damage the tester.）
Voltmeter function can be set as "ON/OFF" in the voltmeter under Additional
Functions.
When Voltmeter is ON and no other operations after tester startup, screen will
show the startup interface all the time. In this situation, 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, screen shows the startup interface as below figure 2.
After 2seconds, it automatically enters the battery test program.Press MENU key
within this 2 seconds, it enters additional function program.

3.3 Battery Test
After entering battery test program, tester displays the tester model and
version approx. 2 seconds, see figure 3
Figure 3, Interface with tester model and version
The bottom line of the interface shows the current date and time, whose format can be
edited and adjusted in the Additional Functions. For details, refer to Additional Function
3.8.10 "Set Date and Time" and 3.8.11 "Date and Time Adjustment".
