Chapter 4: Battery Test
Additional Test Requirements
For a more decisive result the tester may ask for additional
information or probe deeper into the battery’s condition. The
following messages and instructions may appear before the
analyzer displays the results of your test.
System Noise
To perform a correct measurement the tester requires
the vehicle to be in rest. After the car has been driven
some vehicle specific systems might still be active in the
background. The tester will detect this and displays the
message SYSTEM NOISE. When this message appears switch
off all consumers(radio, airconditioning) and remove the key
from the ignition. As soon as there is no more activity in the
vehicle the tester will continue testing and display the test
result.
Unstable Battery Detected
A battery that is weak or that has just been charged may retain
enough electrical activity to be detected by the analyzer
and will adversely affect the test results. A fully charged
battery should stabilize quickly, after which the analyzer
will automatically retest. Weak batteries should be charged
and retested. If the battery is fully charged, check the clamp
connections.
Surface Charge
The battery can hold a surface charge if the engine has been
running or after the battery has been charged. The tester may
prompt you to remove the surface charge before it displays a
test result.
1. Follow the instructions indicating when to turn the head-
lights on and off (IN-VEHICLE)
2. The tester will resume testing after it detects that the sur-
face charge is removed.
Deep Scan Test
In some cases the tester may need to further analyze the
battery to determine whether the battery should be replaced
or it has a significant chance to be recovered. It will then
conduct a Deep Scan Test of the battery for a few seconds.
This test will typically be performed on batteries that are in a
low state of charge.
