If the source is switched off, the value of the voltage that is fed to the input of the
device is displayed in the window. The nature of the voltage is also displayed. The direct
voltage is accompanied by the abbreviation VDC, alternating voltage by the abbreviation
VAC.
To exit the mode, press the «F6 / Close» or «EXIT» button.
