Tap [OK], test data will be shown on the screen.
Notes:
It is unnecessary to perform charging system and start system test after finishing
battery test, but battery test must be done before undergoing charging system and
starting system test.
11.4.3 Outside the vehicle test
It only applies to battery test and detecting floating electricity will be ignored
while performing battery test.
On Fig. 11-4, tap [Outside the vehicle] to select battery test standard.
The following operation steps are identical to Steps 6~7 in Chapter 11.4.2
Battery test. Please refer to it for details.
11.5 Precautions On Battery Test
For the purpose of getting accurate test results, unless otherwise special
required, all loads need to be power off such as headlamp, engine etc. before
testing battery.
The operating time required for charging system and actuation system test
varies from person to person. If the engine does not start or accelerate within 30
seconds, the system will prompt you “receiving timeout” and return to the initial
status.
Whether Engine is off or not has no influence on charging and actuation test
result after increased speed is detected, but other loads need to be powered off.
The accuracy of battery voltage, charging voltage, start voltage is 0.01V in test
results; CCA (Cold Cranking Amps) precision is 5CCA.
Generally, charging voltage value is greater than starting voltage.
Charging voltage range is as follows: 13.8--14.5V for domestic vehicle;
13.3--15.5V for imported vehicles. The voltage varies with different car models,
so you have to judge based on related vehicle models. In general, the DC
voltage is stable, but it also varies with different revolution speed.
Starting voltage range: The value higher than 9.6V is regular, otherwise it is too
low. Due to different situations, whether the starting voltage is higher or not does
