The error screen will be followed by:
Pressing the Output On/Off button at this time will bring the user back to the Remote Sense On screen. Remote sense must be
turned off or the load wires must be improved to allow calibration of remote sense.
If the remote sense calibration completed normally the display will return to the REMOTE SENSE COMPLETE screen.
System set up
Remote sense
Pressing Output On/Off button will now return the system to the following screen:
System set up
exit
To change another setup item at this time you may use either control to select that option. To exit setup, rotate either control
until the following screen is displayed then press the output on/off button.
Now set the current to at least as much as you would expect your load to consume. More is better if your load wires are
capable of handling the current. When ready press the output on/off button.
The power supply will now measure the output current and the total voltage drop in the load wires and use these values to
calculate the resistance of the load wires. As long as Remote Sense remains enabled the power supply will use this resistance
value to calculate output voltage based on output current. It will then adjust the output voltage at the power terminals in real
time to correct for the drop in the load cables.
If, during the remote sense setup, the lead resistance is so much that remote sense will not be able to operate reliable the
following error screen will be displayed.
