keithley

Keithley 2182 driver class.

Initialize Keithley data labels, name, and connection parameters.

Parameters:

  • port – string name of port, e.g. ASRL::1::INSTR.

  • po2_intercept – calibrated pO2 sensor voltage vs temperature intercept.

  • po2_slope – calibrated pO2 sensor voltage vs temperature slope.

  • data_label – labels for DataTuples. get_data() returns temperature, pO2, and pO2 sensor voltage, and corresponding labels should match entries in DATA_COLUMNS.

  • name – name of instrument.

Raises:

ValueError if data_label does not contain 3 entries. –

connect() → None

Connect to Keithley 2182 nanovoltmeter.

get_data() → List[DataTuple]

Get po2 sensor data.

Returns:

DataTuples in the order of sensor temperature in deg C, po2 in atm, and sensor voltage in Volts.

shutdown() → None

Disconnect from Keithley 2182.

start() → None

Start pO2 measurement. Not implemented.

stop_measurement() → None

Stop pO2 measurement. Not implemented.
