Details

Reads an instantaneous voltage value from an analogue input channel (analogue-to-digital converter, or ADC) or an analogue output channel (DAC) that you have previously set.

Results are given in absolute voltage units. Voltage results always have a capital V appended with no space (e.g. –0.25V). (Voltage specification is preferred to raw ADC/DAC values as there is little room for confusion.)

Examples

Info: State: 5 (ECG_Lead_I) +0.3760V

Info: State: 7 (signalgenerator) –5.200V
