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.
