Appendix A: Temperature Calibration
Temperature calibration is performed to optimize system accuracy. The controller is factory
calibrated using a certified National Institute of Standards and Technology (NIST) traceable
measuring instrument, but during its operating life may experience some zero drift due to aging
of components. To recalibrate the system, an independent measuring instrument with
reference probe is required to compare actual readings to readings displayed on the controller.
To calibrate the system’s temperature sensor:
Ensure that the provided Pencil Sensor (RTD) is plugged into the jack labeled 1.
SENSOR on the back of the unit.
Ensure that the shaft of the Pencil Sensor (RTD) is in contact with the fluid or 2.
vapor temperature that needs to be controlled.
Place an NIST sensor (with independent measuring instrument) or 3.
t
hermometer in the same fluid or vapor as close as possible to the machine’s
Pencil Sensor (RTD).
Use the SOLO controller to adjust the temperature setpoint to -40 °C (or other 4.
required temperature).
Allow the system temperature to stabilize ( i.e. , wait approximately 10 5.
minutes).
Press the SET and Rotate buttons on the SOLO controller at the same time to 6.
unlock the controller.
Note: The Set button is used to confirm the setting value. It is also used to navigate
between function modes. The Rotate button is used to change parameters within each
function mode.
