Alternatively:

Plug the probe’s thermocouple into the T-AIR connector

located at the bottom of the analyzer. 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 LIST screen (refer to Calibration on page 66).

3. Use the ▲▼ buttons to highlight T-Air, and then press ENT to display

the CALIBRATE TA-ZERO screen.

NOTE: “Measured” is the current temp

erature reading,

while “Applied” is a known temperature that will be applied

for calibration purposes.

4. Set thermocouple simulator to 0 °C (32 °F), and then use the ▲▼ and

◄► 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 ▲▼ and ◄►

buttons to enter an applied value that exactly equals the thermometer

reading.

NOTE: The calibration range is from 0 to 5 °C (32 to

41 °F

). An attempt to calibrate outside this range will

cause the message “Applied Value High” (or Low) to

appear at the bottom of the screen.

5. Wait until the measured reading stabilizes, and then press ENT to

calibrate the TA-Zero Measured value to that of the applied value; after

which the message “Good Calibration” should briefly appear followed by

the CALIBRATE TA-SPAN screen.
