The measuring range is from DC 0.0V up to 50.0V maximum. If the voltage is over this limit, the display will show as below
5.4 Starter Test (12V/24V vehicles)
This test helps determine the condition of the starter motor and battery during cranking of the engine. The drop in battery voltage during the starting process
is measured, which can indicate if the battery has aged or the starter has a problem.
1. Connect test leads with battery clamps to meter
2. Turn Selector Dial to Voltage Mode (V position)
3. Select Starter Mode
then press button to continue
4. Display will flash as below to show clamps need connecting to battery
5. Connect red clamp to battery po) and black clamp to battery negative(-)
Note:
The tester will automatically detect whether it is a 12V or 24V vehicle based on the battery voltage detected after clamping.
6. Once connected, the battery voltage will be displayed as shown below
7. While this display is shown, start the engine until it runs
8. The voltage drop will then be captured as shown below
