Caution:
The analog input is always active. Even if the load is in the “OFF”
state at the front panel or through remote control, the load will draw current when
voltage is applied to the analog input.
3.2.6 Load Coarse/Fine Increase/Decrease Adjustment Key
The load current step change or resolution is shown in Table 3-2 for each load module.
Pressing and holding any one of the four arrow keys for more than 1 second speeds the step change;
either release the arrow key to stop at a value, or wait for the adjustment to reach the maximum or
minimum load current setting.
