3.2 Operation – Setup and OCP Test
The SLD-series dual input DC loads can operate in five modes: Constant Current (CC),
Constant Voltage (CV), Constant Resistance (CR), Shorts, and Dynamic. Dynamic mode allows
controlled current transitions between two states in CC.
The following procedure is outlined in Figure 3-4. The number within parentheses following a
front panel key name, refers to the labels in Figure 3-1 and Figure 3-2
3.2.1 Overview of Front Panel Operation
Select channel A or B (2) to input settings. Next, set Limits (15) for the go/no go upper and
lower limits for voltage and current. Then configure (14) the remainder of the system
settings for V-sense control, load On voltage, load Off voltage, and OCP test setup.
Once you’ve set up the initial parameters, use the MODE key (3) to select CC, CR, or CV
mode and set up the applicable parameters for each. Select either Static mode (11) for any
of CC, CR, or CV, or Dynamic mode (11) for CC only. In Dynamic mode, use the Dynamic
Setting key (12) to set values for the required T
HIGH , T LOW , and Slew parameters.
Finally, apply load to the input terminals with the Load key (10), which toggles the Load On
and Off.
