TCON CommError

[gitansh95]

The following error occurred while trying to acquire current fluctuations at various temperatures using SMU and TCON :

Traceback (most recent call last):
  File "time_resolved_IV.py", line 110, in <module>
    main()
  File "time_resolved_IV.py", line 102, in main
    measure_current(xsmu_driver, xtcon_driver, iterations)
  File "time_resolved_IV.py", line 37, in measure_current
    temperature = xtcon_driver.getSampleTemperature()
  File "../modules/xtcon/tcon.py", line 159, in getSampleTemperature
    T = self.readSensor2Temperature()
  File "../modules/xtcon/tcon.py", line 141, in readSensor2Temperature
    self.check_timeout (timeout, 'Read sensor 2')
  File "../modules/xtcon/tcon.py", line 127, in check_timeout
    raise CommError ('TCON_CommError: ' + str (context))
tcon.CommError: TCON_CommError: Read sensor 2

The python script running was in PR #3, commit : ceb950e, file user_scripts/time_resolved_IV.py

The python program ends after this error is raised, but the TCON continues to hold its isothermal setpoint.
