Service And Maintenance
12.1
Calibration
The Battery Charger Analyser must at one yearly intervals, be calibrated to ensure that
the measurement circuits are still within specifications. Where these are outside of
acceptable tolerance then a full calibration must be performed. This procedure is
described in the calibration section.
12.2
Cleaning
At yearly intervals it is advisable to ensure that the airflow for the heat exchanger is 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 heat exchanger 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.
12.3
Battery Backup
The internal parameters of the Battery Charger Analyser are maintained by a single coin
cell mounted on the display PCB at the front of the unit. This should be changed every
4-5 years. If it should fail during use this will be indicated by the unit requesting the
date and time when power is applied. Calibration data is unaffected as this is stored in
FLASH memory.
The cell is a standard Lithium button cell number CR2032. When
replacing the battery please observe the correct methods of disposal
of the old battery in accordance with your local regulations.
