Battery charger/analyser : Operators Manual
5.2.2 Capacity Test Calibration Check.
Connect the measuring equipment in accordance with the calibration equipment
connection diagram to Channel A.
• Set the battery charger to test mode.
• Set capacity test amps to 25A using the ASET key.
• Set the termination voltage to 20V using the VSET key.
• Set the capacity test duration to 010 using the TSET key.
• Press START to begin the capacity test process.
• Allow the capacity test current to stabilise.
• Take note of the readings of both the measurement equipment and the
readings on the charger display.
• If the readings are more than 1 digit different then the recalibration procedure
must be followed to correct the difference.
• Once this process is completed press STOP to end the capacity test.
• Capacity test circuit calibration is complete.
• This process must then be completed for channel B.
5.3 RE-CALIBRATION
The TS25 MKII keeps a calibration constant value stored internally which it uses for
calculating true voltage and current from it’s internal measurement circuitry. Because
of component tolerances and tolerance drift with time (decay) the values created at
manufacturing time can cause measurement errors due to this decay. Modern
components are much more stable than their older counterparts so re-calibration is
less necessary, but the checking is essential to ensure that the correct voltages and
currents are used to charge and capacity test your batteries.
If the procedures identified above requires the unit to be recalibrated then the
following re-calibration method needs to be followed.
5.3.1 Charge Re-Calibration:
Connect the measuring equipment in accordance with the calibration equipment
connection diagram to Channel A.
• Set the battery charger to CHRG mode.
• Set the charge mode to CC using the PROC key.
• Set charge amps to 10A using the ASET key.
• Set the voltage threshold to 30V using the VSET key.
• Set the charge duration to 0.1H using the TSET key.
• Press START to begin the charge process.
• Allow the charge current to stabilise.
• Press the ENTR key rapidly twice
• The display will briefly display CAL.
• To re-calibrate current press ASET.
• Enter the number of amps displayed on the measuring equipment, then press
ENTR.
• The charger will adjust the charge amps so that the measuring equipment will
then display the same as the charger.
• To recalibrate voltage press VSET
• Enter the number of volts as displayed on the measuring equipment and press
ENTR.
