LabView
The User Interface
To start the program move the power button to “on” and push start on the labview program.
“Sample Voltage in mV” will read the voltage from the Tektronix DM5120 Programmable Digital Multimeter. (potential difference between the blocks)
“TC_V in mV” will read the voltage from the Keithley 195A Digital Multimeter. (Temperature gradient between the blocks)
The meter 1 graph will show the sample voltage as it increases or decreases over time.
The meter 2 graph will show the temperature voltage between the blocks as it increases or decreases over time.
“Voltage” will apply heat to the hot block via the Keithley 2400 Source Meter. Typically we apply 5V to the hot block until TC_V in mv reads 0.15 at room temperature (this corresponds to a ΔT of about 3 K see Seebeck Calibration Chart for temperature dependent calibrations).
For more information, the LabView user manual can be found here.
