In the Calibration Parameters screen the user may view and change measurement calibration settings. The
calibration parameters can be viewed with no password but a password is required to make changes.
Calibration parameters include calibrated values for each of the internal resistors and the linearity coefficients
for the resistance ratio measurements. Since the accuracy of the Super-Thermometer depends on these values,
they must be accurate. Refer to Section 9.4.2, ADJUST PARAMETERS (F2), on page 106 for instructions
needed to adjust the calibration parameters.
Apart from the calibration parameters, the Calibration Parameters screen also includes the following configu-
ration fields:
CALIBRATION DATE- used to record the date the Super-Thermometer is calibrated.
SI UNIT LOCK- enables or disables °F as an allowed temperature unit option. When this is set to ON, tem-
peratures may be displayed in units of °C and K only, and °F will not be available as an option for the Unit
setting (see Section 5.7.4.5, TEMPERATURE UNIT (F5), on page 50).
