7) Select Temps from the calibration drop-down
list. It is recommended that both temperature
sensors be calibrated simultaneously.
8) Monitor temperatures for stability by selecting Temperatures and Resistances from the drop-down
menu. You may also graph the Tc and Ts values.
9) When the temperature probes and reference
thermometer are stable at the desired
calibration point within the bath, type in the
reference value, taking note of the units.
10) Repeat step 10 for values approximately 0, 25, 50 and 75 °C.
Note: These exact temperature values are not necessary.
The calibration requires 4 to 5 distinct points over the probe range.
A minimum of 5 reference values must be entered before the Calculate icon is enabled.
11) If the Ts Read and Tc Read values compare with the reference temperature, within the expected
tolerance, record your data manually and close the window, then proceed to Section 5.2.3,
Temperature Probe Reinstallation.
Otherwise, continue with steps 10 through 12 in order to calculate and save new coefficients.
12) After entering the minimum required number of
readings, or more, click the Calculate icon. The
new coefficients will appear on the bottom portion
of the window.
