Considerations For Operating In Constant Resistance Mode 91 A Considerations For Operating In Constant Resistance Mode The Agilent Electronic Loads implement Constant Resistance. (CR) mode by using either the CV circuits or CC circuits to regulate the input. The low range is regulated with the CV circuits, using the input current monitor as the ref ...

92 Considerations For Operating In Constant Resistance Mode If large resistances are required, the accuracy can be improved by reading the voltage and current directly from the load, calculating the actual resistance, and then adjusting the programmed value accordingly. This technique is most practical in applications requiring a fixed resistive lo ...
