Confirm the selection and start the measurement with "ENTER". After completion of the test, the following results are available: cold cranking amperage, internal resistance of the battery and battery voltage. Use the "Up / Down" keys to view the results. Notes on the test results Battery capacity normal Battery voltage –...
Examples Replace battery when capacity is too low Charge battery when the battery capacity is OK and the voltage is too low Charge battery and measure again if battery capacity is 75 % and voltage is too low You can return to the function selection by pressing the ”ESC“ key. Battery voltage at engine start Turn off the engine and the ignition.
Start the engine. The unit displays the battery voltage before and the lowest voltage during the start-up process. The lowest voltage during the start-up process should not fall below 9.6 V for one battery (12 V) and 16 V for two batteries (24 V). Reference chart starting voltage >10.7 V good...
Select function 3 with the "Up / Down" keys and confirm with "ENTER". The unit displays the current charging voltage, the minimum measured charging voltage and the target voltage at maximum load. The minimum charging voltage at maximum load should not fall below 12.80 V for one battery (12 V system) and 25.60 V for two batteries (24 V system).
After completion of the test, the following results are available: Target value charging voltage, maximum value charging voltage and maximum limit value and target value charging voltage, minimum value charging voltage and minimum limit value. Use the "Up / Down" keys to view the results. The maximum charging voltage should not exceed 15.00 V for one battery (12 V system) and 30.00 V for two batteries (24 V system).
