13. To printout the results, just press key on the Analyzer, the printer will start printing.
14. Pressing the key will exit and return to the main menu screen (Fig.46).
Grounding Test:
This test is available in only. The purpose of this test is to check the grounding cable condition to the
engine body. If the grounding circuit is not good, it may pose a lot of problems to the vehicle ECU. The Analyzer will
measure the contact resistance from the engine body to the battery terminal, then it will display the results and the
recommendations after each test.
Again, this test can only be performed with a 12V battery. If you need to check grounding on a 24V vehicle system (12V
x 2 batteries), all you have to do is to clamp onto one of the two batteries that provides the 12V for the operation.
If you had accidentally clamped onto a 24V battery output, it will remind you with the display as shown below (Fig.62
and Fig.63):
In this case, clamp the tester onto one of the 12V batteries that has a negative terminal connected the chassis
(see Fig.64 below).
Note:
To conduct Ground Resistance test on a 24V (12V x 2 batteries) system, always look for the 12V battery with its
negative terminal connected to the vehicle chassis (see Fig.64 above). Clamp the tester clips onto the battery
terminals to be able to proceed with the test.

1. Make sure that the engine is switched OFF. Attach the clips onto the battery terminal posts and the Analyzer
will power up and light up the LCD display screen as shown below:
