To set the positive current limit:
To set the negative current limit:
When the unit is in current priority mode, you can specify a positive or negative output current level,
which will be maintained as long as the output voltage remains within its programmed limit.

Set the Slew Rate
The voltage slew rate determines the rate at which the voltage changes to a new setting. This applies
to both voltage settings in voltage priority mode, and voltage limit settings in current priority mode.
When set to MAXimum, INFinity, or to a very large value, the slew rate will be limited by the unit's
listed programming speed and bandwidth. This setting can be used to prevent crossover into current
limit while up- and down-programming capacitive loads, or to limit programming response to a
controlled rate. Use the following equation to calculate the maximum slew rate limit to ensure smooth
and linear up- and down-programming performance.
Max slew rate (V⁄s) = (Current limit setting (A) – Load current (A))/(Load capacitance (F))
The current slew rate determines the rate at which the current changes to a new programmed setting.
This applies to both current settings in current priority mode, and current limit settings in voltage
priority mode. When set to MAXimum, INFinity, or to a very large value, the slew rate will be limited by
the unit's listed programming speed and bandwidth.

Set the Output Resistance
Requires firmware version B.03.02.1232 and up.for models RP793xA and RP794xA.
Output resistance programming is mainly used in battery testing applications and only applies in
voltage priority mode. It is used to emulate the internal resistance of a non-ideal voltage source such
as a battery. Values are programmed in ohms.
