====The User Interface====
{{:seebeck:equipment:seebeck_interface.png|}}
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:equipment:LabView:Seebeck Calibration Chart|Seebeck Calibration Chart]] for temperature dependent calibrations).
