Abstract:
1. A method of operating a temperature calibration device having a plurality of Peltier cells to heat or cool a device to be calibrated, the method comprising: connecting the plurality of Peltier cells to each other in a first configuration when the Peltier cells are to cool the device to be calibrated; applying a first voltage having a first polarity to the Peltier cells that are in the first configuration when the Peltier cells are to cool the device to be calibrated; connecting the plurality of Peltier cells to each other in a second configuration when the Peltier cells are to heat the device to be calibrated, the second configuration being different from the first configuration; and applying a second voltage having a second polarity to the Peltier cells that are in the second configuration when the Peltier cells are to heat the device to be calibrated.
