| Constant current (CC) mode | When a current value is specified, the current is kept at that value even when the voltage changes. |
|---|---|
| Constant resistance (CR) mode | When a conductance value is specified, the product sinks the current proportional to the voltage variation by using the value as a proportionality constant. |
| Constant voltage (CV) mode | When a voltage value is specified, the product runs the current so that the voltage is kept at that value. |
| Constant power (CP) mode | When a power value is specified, the product runs the current so that the power is kept at that value. |
| Arbitrary I-V characteristics (ARB) mode | The desired load characteristics can be set by specifying multiple arbitrary voltage values and current values as I-V characteristics. |
