As we discussed yesterday, there are some commands that would be very helpful to have included in the IOC for the Keithley 6517B;
Setting AUTORANGE for the current measurements. There are 10 different ranges, and to optimize accuracy I'd rather avoid fixing the measurement range. (This is not needed for voltage measurements with only three ranges, and we will always be far below the lowest range, 2 V). In SCPI this would be
":SENS:CURR:RANG:AUTO ON"
":SENS:CURR:RANG:AUTO OFF"
Enable and disable zero check. Zero check shunts the input, which protects the device when connecting circuitry, and since we will be alternating between current and voltage measurements, this can also help dissipating residual charges on the electrodes, so it would make sense to be able to toggle this on and off. Also, it is on by default and nothing is measured if I forget to turn it off, so controlling this in the script will ensure such mistakes are avoided! SCPI:
":SYST:ZCH ON"
":SYST:ZCH OFF"
