My 2450 seems to be restricting voltages to 40 V. For example, I put a 50 V input into the device and received a readout of 40V. Anything below 40V below worked fine. What might the issue be?
This would likely be due to the interlock not being engaged. Please refer to the 2450 manual: https://www.tek.com/en/source-measure-units/keithley-smu-2400-series-sourcemeter-manual/models-2450ec-2460ec-and-2461ec-potentiostats-and-galvanostats-users-manual
