With sensor inputs, the displayed values are the voltages read by the analog
channels. For example, by using the voltage divider 10.000/1 applying 20 kV
on the sensor, the measurement will show 2 Volt. For the current sensor 80 A/
150 mV, applying 80 Amp on the sensor the measure will be 0.150 Volt.
