07: Imon measurement calibration
On the rear panel terminals short ‘Imonitor’ to ‘Icontrol’. Ensure that there is no load connected to
the unit and connect the voltmeter from ‘Imonitor’ to ‘Common’. Select option 7 from the Calibration
menu (Imon measurement) and press OK. The unit now gives an output of about 1 Amp; measure
the voltage at ‘Imonitor’ and enter the output current this represents (e.g. 5 times the current
measured for the 0V to 10V range) to the nearest mA and press OK. After a few seconds the output
changes to about 50 Amps; measure and enter the current represented by the voltage at ‘Imonitor’
to the nearest mA and press OK. After a few seconds the display changes to the calibration menu
output voltage control is now calibrated.
08: Imon setting calibration
On the rear panel terminals short ‘Imonitor’ to ‘Icontrol’. Connect the current measurement system
directly across the front panel terminals or alternatively connect a direct short-circuit. Select option
8 from the calibration menu (Imon setting) and press OK. The unit self calibrates; during this time
the output current will be switching between different levels. After a few seconds the display
changes to the Calibration menu; output current monitor is now calibrated.
