Keithley: meas_func: VOLT fail in an hidden way if it is not supported
I was trying to setup meas_func: VOLT
for a Keithley 6487, for ID01.
But the controller was always exposing meas_func: CURR
.
In fact this controller dosn't support VOLT
.
I would prefer it to fail at the initialisation with something like:
raise RuntimeError(f"The controlller {name} (model {model}) dosn't support meas_func=VOLT")
