Switch ON / OFF Key Sound Beep
Whenever a key is pressed, there is a corresponding beep sound which can be heard to indicate that a key has been
pressed. This sound can be switched ON or OFF by doing the following:
1. Go to the Main Menu as shown in (Fig.4).
2. Press and hold key for about 3 seconds and a long beep sound will be heard which indicates that
the change has taken place.
3. Then, press any key and the sound is OFF
.
4. To reverse back, do the same procedure as mentioned in step 2 and the sound will be switched ON.
Car / Truck Battery Test
This test is intended for
12V batteries
but not for 24V
.
The reason is, most trucks that use 24V systems have two 12V
batteries connected in series to produce 24V. To test on 24V system (12V battery x 2), disconnect the connection
between each battery and test one battery at a time. The test results of an individual battery are more accurate than
testing two batteries at once due to the unwanted resistance created by the cable joining the first battery to the second
battery that makes 24V. So, the battery test is catered for 12V batteries only.
Performing Battery Test While it is Still in the Car or Truck:
A vehicle that was running must have its engine OFF first and then switch ON the headlights for 30 seconds to remove
the surface charge. After the headlights are switched OFF, let the battery rest for at least 1 minute to recover before
testing commences.
The car or truck engine and all other accessory loads must be
OFF
during test in order to have accurate results.
When attaching the analyzer clips, make sure that the battery posts were not oxidized or badly corroded. Clean
them first before clamping to it. Do not clamp onto the steel bolts directly which may give inaccurate and inconsistent
results.
If the red and black clips were accidentally clamped directly on to the 24V output terminals of the battery while
testing truck batteries, the Analyzer display will show (Fig.7 and Fig.8) as below:
This is to indicate that it cannot test a 24V battery. In this case, if the truck consists of two 12V batteries, then test
them individually (one at a time) see (Fig.9):
Testing on stand-alone Batteries:
Clean the battery posts with a wire brush prior to testing. For side post batteries, install stud adapters. For better results,
do not use steel bolts.
1. Clamp the Analyzer red clip to the battery positive terminal (+) clamp the black clip to the battery negative
terminal (-). The Analyzer LCD will light up with the wake-up screen (Fig.10) on following page:
