2110/2120 OPERATOR’S MANUAL – SECTION 6 When operating in Controlled Current (CC) mode, a compensation circuit is required to ensure ac- curate output current. Since the load is a critical circuit component in CC mode, the inductive and resistive values of the load will determine the required compensation values. While the factory- default compensation setting will be sufficient for some applications, the compensation setting may also be adjusted in the field.
