- Left wheel
- voltage selection
- Right wheel
- current limitation selection
- Validate button
- exit the "Voltage and Max current control"
- Supply X
- select the power supply for the voltage and current limitation.
Voltage and Current Calibration
Calibration is necessary to increase the precision of the laboratory power supply. It is controlled by the ATmel microcontroller.
- Voltage calibration is achieved by measuring the power supply voltage with a multimeter and entering the measured value in LPS.
- Current calibration is achieved by measuring the output current while the output is under some load. The load has no importance.
The display is the following:
