LSU220A : Load Support Unit
Operators Manual
5 CALIBRATION
The LSU220A has two displays which show Voltage and Current. These are electronic
displays which will require regular checking for their accuracy. Intelligent Charging
recommends that the calibration check procedure is followed annually.
To calibrate the unit the following equipment will be required.
1.Calibrated voltmeter capable of reading 24V to one decimal place.
2.Calibrated ammeter capable of reading up to 200A to one significant digit, or a
calibrated ammeter shunt and millivoltmeter combination.
The equipment will need to be connected as shown in the following figures.
