7.1
Calibration
The Battery Charger Analyser does not require regular calibration and the meter dials
must be used for guidance only. A yearly check to see that the unit is still operational
can be undertaken. This can be done to verify that the output voltage of the unit is still
set to 14.4V in parallel mode and 28.8V in series mode. With Boost ON. The voltage of
each internal SMPS can be adjusted by removing the front panel and adjusting the
individual supplies to 14.4V each. The position of the adjustment potentiometer is
shown thus: -
This adjustment must be carried out in a no load situation and with the unit in the
STOPPED mode. Measurements must be taken at the power supply output terminals,
marked MAIN OUTPUT on the sketch above.
7.2
Cleaning
At yearly intervals it is advisable to ensure that the airflow for the power supplies are
not obstructed by dust and dirt. To clear any dust and debris the unit must be
disconnected from the mains and remove the battery leads from the unit. The cover
must be removed and the power supplies blown clear by the use of a high pressure air
gun. Where this is not available the use of pipe cleaners or similar must be employed to
clear the dust built up.
Observe all safety precautions when using high pressure air. Wear ear
defenders and safety goggles and do not point high pressure air at people or
animals.
