    1.6.6 Additional Capabilities REMOTE SENSE CONFIGURATION You can enable or disable the PLS600 Remote Sense capability and set the lead resistance 2.0.1 with the following SCPI commands. In addition, you can command PLS600 to calculate the lead resistance by executing the 2.0.2...
  • Page 3 Local In Local mode, the user controls PLS600 via the front panel. While in Local mode the user can achieve nearly full capability via the SCPI command interface, EXCEPT for setting operational voltage and current setpoints and activating the output. The SCPI command to deactivate the output will be executed.
  • Page 4 1.0.8 Series Mode In series mode the analog output is activated and this output is proportional to the output voltage of the power supply. When this output voltage is fed to one or more analog inputs of other supplies and the analog inputs of those supplies are set for Analog Voltage Control the supplies will match output voltages.

    1.6.2.1 Analog Input Scaling You can select 3 volt, 5 volt, or 10 volt scaling for the analog current input. This is the value which represents the maximum model-specific current. For example, if you have the 400V 2.5A model and have selected the 10V scaling, then 10 volts applied across the Analog Current channel will result in a 2.5 amp setpoint.

    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”...
