Device Keithley 6517A for reading voltage output

Hello,

I use the device Keithley 6517A as a voltage supply and as a current reading.

I use the vi "V-Source Output.vi" to select the voltage value in output (-1000 V to +1000 V) and after, I do a reading current.

Before doing my current reading, I would like to check that the output voltage is correct. Does anyone know if it is possible to know this output voltage?

Thank you.
