Slew Rate
Slew rate determines the rate at which the input level changes to a new programmed value. Slew rate can be set at the front
panel ( 
, 
and ENTRY keys) or via the GPIB (CURR:SLEW command). This slew rate remains in effect for the immediate, triggered, and transient level changes previously described.
There are 12 discrete current slew rates within each
Constant Resistance (CR) Mode
In this mode, the load will sink a current linearly proportional to the input voltage in accordance with the programmed
resistance (see Figure 
, 
and 
keys) or via the GPIB (MODE:RES command). The CR mode parameters are described in the following paragraphs.

Ranges
Resistance may be programmed in any of three overlapping ranges (low, middle, high). The range can be set at the front
panel (
, 
, and ENTRY keys) or via the GPIB (RES:RANG command). Any value in the low range selects the low range. Any value that is within the middle range and above the maximum
Immediate Resistance Level
The resistance level can be set at the front panel (
and ENTRY keys) or via the GPIB (RES command). If the CR mode is the active mode, the new setting immediately changes the input at a rate determined by the voltage or current slew setting (see description below). If the load is not in the CR mode, the new setting is saved for use when the mode is changed to CR.
