MP73P+ : Battery charger/analyser
Operators Manual
•
Connect a good quality 24V battery to the Battery Charger Analyser.
•
Measure battery voltage and verify the Battery Charger Analyser display is within
tolerance.
•
Perform a capacity test at approx 13A.
•
Measure the current passing out of the battery and verify that the Battery
Charger Analyser display is within tolerance.
•
Perform a charge at approx 13A.
•
Measure the current being passed to the battery and verify that the Battery
Charger Analyser display is within tolerance.
If these parameters are outside of specification then the
Calibration Adjustment
procedure should be followed.
If these check show that the Battery Charger Analyser is within tolerance and no
adjustment is necessary then the following procedure need to be applied to the Battery
Charger Analyser to reset the calibration date to the current date.

When requested enter the 4 digit serial number of the unit and press
‘ENT’
.
•
A confirmation screen will be displayed.

Making Calibration Adjustment
If the calibration check has been performed and the unit is out of tolerance then a
calibration adjustment will need to be performed. the following procedure needs to be
observed in order to perform a calibration adjustment.
A good 24V battery and voltmeter and ammeter will need to be connected to the unit
during this procedure.

ADJUSTMENT
•
When requested enter the 4 digit serial number of the unit and press
‘ENT’
•
When requested enter the measured battery voltage and press
‘ENT’
•
The charger will then set up a charge of approximately 14.0A
•
Allow the charge current to stabilise.
•
When requested enter the charge current and press
‘ENT’
•
The charge will then set up a discharge of approximately 14.0A
•
Allow the capacity test current to stabilise.
•
When requested enter the capacity test current and press
‘ENT’
•
The battery voltage is also measured again here to calculate the lead voltage
drop to be used in voltage readings.
•
When requested enter the Battery voltage and press
‘ENT’
