Once the calibration has been initiated it will take somewhere between 30 seconds and 2 minutes depending on sensor
and temperature measurement stability. During this period, the abort sequence can be initiated as shown with the active
ABORT button.
When the first calibration point is accepted, the status box will prompt the user to place the sensor in the second solution
of known value.
Wait until the sensor and temperature values are stable in the second solution.
Enter the desired value and initiate calibration by clicking the CALIBRATE button.
