10. Position of the calibration trimmer behind the back panel
Always follow the rules and recommendations of the power supply manufacturer before
connecting the module.
4.5 Reference voltage tuning
For expert only, need hi-precision voltmeter (20.000 points)
A trimming potentiometer allows you to fine tune the voltage span of the analog converters.
To ease the setting, there is a dedicated calibration preset (see 5.1.1) that gives various reference
voltages on all CV outputs:
Connect on CV out 1, and turn the trim to adjust the voltage precisely to 10,666 Volts.
The other outputs are not used for calibration but rather to check that the module is OK at
manufacturing.
