LSU80A : Load Support Unit
Operators Manual
5 CALIBRATION
The LSU80A 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 80A 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.
