Noted : If test on the vehicle, please make sure to disconnect all loads, and
don't out the key in the ignition position and must close the door . Connect
the red clip to the positive (+) terminal of the battery and the black clip to the
negative (-) terminal. After connecting, shake the clip back and forth to make
the connection firm. Before testing the battery, two clips are required to
connect the terminals firmly.The best test location is the connection port of
the battery. If the battery cannot be connected from the wiring port, you can
try to test on the jumper port, but the measured data may be lower than the
actual value.

Good battery but low current, recharge before using.
Note: If the battery is not fully charged before retesting, it may
result in erroneous readings. If the display again after
charging, test again after charging, please replace the battery.
Replace
The battery is near to or already reached the end of the using life,
replace battery otherwise, bigger danger will be followed.
The replacement of the battery may be due to a poor
connection between the car's cable and the battery. After
disconnecting the car battery cable and battery, please
use the outdoor mode to test the battery again, and then
decide whether it needs to be replaced.
Bad cell, Replace
Battery interior damaged, bad cell or short circuit, replace battery.

Attention: If “Replace” resulted from IN-VEHICLE mode, it might be the
reason that vehicle cable is not well connected with the battery,Ensure to
cut off the cable and retest the battery under OUT-OF-VEHICLE before
making a decision to replace battery.
Cranking Test
Important note: Before starting the test, check the drive belt of the generator.
If the belt is shiny or worn, or lacks proper tightness, the machine will not
reach the speed level required for detection.

Description
Normal cranking
The cranking voltage is normal and the battery is fully charged.
Cranking low
The cranking voltage is lower than the normal value, and the
starter malfunction is diagnosed.
The battery must be
charged
The battery state of charge is too low for the starter test. The
battery must be fully charged before starting the system test.
Re-test after charging the battery.
The battery must be
replaced
Before starting the cranking system test, the battery must be
replaced.
The engine does not
start
It is detected that the vehicle cannot be started.
Charging Test
Once the cranking system test is completed, the screen will alternately
display the cranking system test results and prompts. Press the Enter key to
test the charging system. Press the Enter key to perform charging test.
Follow the instructions on the screen: Increase RPM to 2500 r/min and keep
it 5 seconds, Press ENTER to continue
1. Increase the throttle when closing the load
2. The engine speed is detected and the engine is idling
3. Test the generator when the load is off and idling
4. Turn on the headlights and blower when the engine is idling
5. Test the generator when the load is clocked in and idling
6. Increase the throttle when opening the load
After the process is over, the tester displays the test results of the charging

The system shows that the generator output is normal
With output
voltage
Generator output detected.
√ Check the belt to ensure that the generator rotates with the
engine running. Replace the broken or slipped belt and retest.
Check all connections on the generator. Especially the connector
connected to the battery. If the connector is loose or severely
corroded, clean or replace the wire and retest.
√ If the belt and joint are in good condition, replace the
generator. (An external voltage regulator for old vehicles may
only need to be replaced.)
Low output
voltage
The generator does not provide enough current to load the circuit
of the system, also it does not have enough current to charge the
battery.
√ Check the belt to ensure that the generator drives the engine to

test.
√ Check the connection between the generator and the battery.
If the connection is loose or severely corroded, clean or replace
the cable and retest.
in conclusion
Description
High output
voltage
The voltage output from the generator to the battery exceeds the
normal limit of the normal voltage regulator.
√ Check to ensure that there is no loose connection and that
the ground electrode is properly connected. If there is no
connection problem, replace the regulator. Most generators
have a built-in voltage regulator, and you must replace the
generator. The external voltage regulator for old vehicles may
only need to be replaced.
Excessive
ripple
Excessive ripple was detected.
√ If one or more diodes in the generator malfunction or the
stator is damaged, these conditions will show that excessive AC
or pulsating current is supplied to the battery.
• Discharge Voltage: When the ignition OFF, engine OFF (Over 20
Minutes), the Discharge Voltage should be around 12V. If the discharge
voltage is lower than 11V, it will be hard to turn the ignition ON. If the
discharge voltage continuously stay under 11V, ii means the battery is
aging and replacement is needed.
• Starting Voltage: During ignition, the voltage will drop to a certain point,
at this minimum point is Starting Voltage (Around 7.5- 9.5V). If the
Starting Voltage continuously stay under 7.5, it means battery capacity
is low and needs to be replaced
• Charging Voltage: When the ignition ON, engine ON. The alternator
will continuously charge the car battery, normally is around 14V
