|
|
Indirect measurement of current by means of integrating DC voltage measurement with AUTO triggering on a defined measurement resistor. This function is always used when a current measurement resistor has to be inserted in a line to the control unit (e.g. UB) for the duration of the measurement. Currents flowing into the control unit register as positive.</P>
