Ensure that the sense cable is installed on the back of the instrument as shown. The only time the

sense cable should be disconnected from the output bus bars is when

If the sense cable is not installed prior to instrument turn-on or becomes disconnected, the unit will

continue to operate. The open-circuit voltage at the output terminals will be anywhere from 0% to

0.54% higher than the programmed value because the regulation point is now maintained through

internal sense-protect resistors. The following table gives the change in voltage at the output

terminals as a percent of the voltage setting when the sense leads are not connected. The readback

voltage will still appear to be at the programmed value.

* For the 20 V RPS units only, the sense leads are buffered so that there is virtually no change in the

open-circuit output voltage if the sense cable is not installed or becomes disconnected.
