Temperature Calibration

4.5.
®
The MAX 5000XL temperature calibration routines will calibrate and verify the
accuracy of the oven temperature throughout the usable range. The oven is
calibrated at twelve (12) preset increments and verified at temperatures that are user
selectable.
Verification Setup
The VERIFICATION SETUP menu allows the verification of the temperature
calibration to be enabled or disabled, and selection of which temperatures are to be
verified. Selecting ALL CAL POINTS will cause verification of twelve (12) preset
temperatures from 50 °C and 575 °C. Four (4) custom temperatures may be
entered to verify only those temperatures used in your processes. Entering a
number above 575 °C will produce a warning message on the display and set in the
default highest temperature of 575 °C. Press [OK] to remove the warning from the
display.
Calibration Module Setup
This menu allows entry of the TCI data. Serial numbers of the interface and probe
used for the calibration and the certification date of the TCI is entered here and
saved for printing in the various reports.
Perform Calibration
This selection starts the automatic process of calibration, and verification if selected,
®
of the MAX 5000XL when the Temperature Calibration Interface (TCI) is connected
to the unit. A detailed procedure begins on page 17. The calibration uses an NIST
traceable device to measure the temperature at the sample level and compare that
to the temperature measured by the control device in the heater. Any difference
between the two readings is then supplied to the MAX
adjust heater current to provide the correct temperature. The verification process
then monitors the oven temperature as it is controlled by the new current settings
and any difference between control and actual temperature measurement is
reported as an error. The systematic process is explained later in this section.
Perform Verification
The Perform Verification selection allows a temperature verification to be performed
at any time, as long as the TCI is connected to the unit.

The VIEW CAL REPORT selection provides information about the last calibration
date and performance. A record of the calibration and verification dates, calibration
