General Instruction
This tester is designed for automotive battery load voltage test,charging voltage test and starter motor test.It is very useful and can be used in vehicle's fault diagnosis and service.
Operation Instruction
Battery Load Test
This test evaluates a battery's ability to crank an engine.The tester draws current from the battery while measuring its voltage level.The voltage level
of a good battery will remains relatively steady under load,but a defective
battery will show a reapid loss in voltage.Battery size(CCA rating)and temperature
will effect test result-follow instruction carelly.
Cold Temperature Effects
Because of the chemical nature of the battery, it will test lower when cold than when warm. For most accurate results, this effect should be compensated for when the battery's internal temperature is below 40°F (4.4°C）. Assum the battery's internal temperature to be the day's high-low average temperature.
Charging Voltage Test (for 12V system only)
This test enables the user to measure the output voltage of the alternator/regulator and check for undercharging or overcharging, which leads to poor battery performance and short life.
Note:
Engine must be at normal operating temperature
.
Starter Motor Test (for 12V system only)
This test identifies excessive starter current draw, which makes starting difficult and shortens battery life.
Note:
Before starter motor test, you must perform battery load test. Only if the battery proves good in the load test can you proceed to the starter motor test. Note the load voltage obtained in the load test
