|
|
Indirect measurement of current by means of integrating DC voltage measurement with AUTO triggering on a defined shunt. This function is always used when a load with integrated shunt is connected to a control unit pin and the current is to be measured on the integrated shunt. Currents flowing into the control unit register as positive.<BR>
