Step 6 – Enter the new calibration material name.
Step 7 – Enter the new calibration material description .
Step 8 – Enter material properties.
At least one temperature and thermal conductivity point must be added to allow the material to be
included in user calibrations. Effusivity values are optional.
If one point is added, that thermal conductivity value will be used at any temperature. If two
points are entered, they will be used to generate a first order thermal conductivity curve and the
thermal conductivity value used will be calculated from the ambient temperature and equation. If
three points are entered, they will be used to generate a second order thermal conductivity curve
and the thermal conductivity value will be calculated from the ambient temperature and equation.
When using calibration materials with multiple entered points, ensure that they are used within
the temperature range set by those points.
Step 9 – Click the Save button.
Step 10 – Repeat steps 5 to 9 as many times as needed.
Step 11 – Click the Close button.
Step 12 – Select the diagnostic material.
The diagnostic material is used in reference material tests.
Step 13 – Enter the Valid ranges.
Enter the lower and upper conductivity values to be used with the calibration.
Step 14 – Enter the test time.
The test time is the total time that current is applied to the sensor chip during a measurement.
The test time must be 10 seconds or less. The factory calibrations use a 0.8s test time.
Step 15 – Enter the start time.
