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 47. The calibration uses an NIST traceable device to measure the temperature at the sample level and compare that to the temperature measured by the probe (temperature sensor) in the heater. Any difference between the two readings is then supplied to the MAX 5000XL control circuits to adjust
heater current to provide the correct temperature. The verification process monitors the corrected probe temperature and the TCI temperature, and reports as an error any difference between the two. 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.
