The Moku:Go M1 has 2 power supplies and the M2 has 4 power supplies.
The power supplies are set and controlled from a pop-out window that is accessible from the top-left menu button. The power supplies are available in each instrument and operate independent of the current instrument.
To activate the power supply, click on the blue highlighted numbers for voltage and current and type in the desired values, then click the slider button. The 'Set' row is where you can set the voltage and current while the 'Actual' row is the measured voltage and current at the banana jack terminals of the Moku:Go.
The CV and CC indicators are for Constant Voltage and Constant Current modes respectively.
