5.7.2. T-Air Calibration Procedure
Step T-Air Calibration Procedure
1
Plug the simulator into the T-AIR connector located at the bottom of the
analyzer.
Alternatively: Plug the probe’s thermocouple into the T-AIR connector
located at the bottom of the instrument.
IMPORTANT: DO NOT attach the probe’s gas hose to the
analyzer’s GAS port, otherwise water will be drawn into the
analyzer!
2 If not already done, turn ON the analyzer and
display the CALIBRATION MENU. Note that
this requires password validation (see page
55).
3 Use the UP (▲) and DOWN (▼) buttons to highlight T-Air, and then press
ENTER to display the CALIBRATE TA-ZERO screen.
NOTE: “Measured” is the current temperature reading, while
“Applied” is a known temperature that will be applied for
calibration purposes.

Set thermocouple simulator to 32° F (0° C),
and then use the UP (▲), DOWN (▼), LEFT
(◄), and RIGHT (►) arrow buttons to enter an
applied value that exactly equals the setting of
the simulator.
Alternatively: Submerge probe tip into an ice-water bath with a
thermometer, wait several minutes, and then use the UP (▲), DOWN (▼),
LEFT (◄), and RIGHT (►) arrow buttons to enter an applied value that
exactly equals the thermometer reading.
