REMOTE SENSE CONFIGURATION
2.0.1
You can enable or disable the PLS600 Remote Sense capability and set the lead resistance with the following SCPI
commands.
RSENSE
Enable/disable Remote Sense
RSENSE?
Return Remote Sense state
RSENSE:RESistance
Set the remote sense resistance
RSENSE:RESistance?
Return the remote sense resistance
2.0.2
In addition, you can command PLS600 to calculate the lead resistance by executing the following sequence:
1.
Short leads which connect to the load at the load.
2.
Execute the command to enable Remote Sense
RSENse ON
3.
Execute the command to calculate lead resistance.
RSENse:RESistance:CALCulate <current> Initiates calculation
The <current> value is the current, in amperes, at which the lead resistance is to be calculated and will normally be toward the
high end of your application.
If the specified current is greater than the maximum allowed for the PLS600 model you are using, you will trigger the error:
-222,”Data out of range”
4.
Execute the command to query the remote sense calculation state.
RSENse:RESistance:CALCulate?
If the calculation is still taking place, PLS600 will report: CALCULATING
When the calculation is complete, PLS600 will report: COMPLETE
If the calculated resistance is too large for practical application of remote sensing, PLS600 will return the error: 181,”Resistance
too large”

CALIBRATION
You can calibrate PLS600 over the SCPI command interface. To do so you must execute a series of steps while opening and
shorting the output. These steps may be performed via the front panel or via SCPI commands. A calibrated high-accuracy digital
multimeter (DMM) and a high accuracy shunt is required to perform calibration.
The sequence of commands is listed below. The sequence must be run to completion. If it is aborted early either by cycling
power or exiting Calibration Mode, you must restart the command sequence from the beginning.
