2.If not already done, turn ON the analyzer and display the CALI- BRATION LIST screen per Section 5.2.

3.Use the ▲▼ buttons to highlight T-Stack,

and then press ENTER to display the CALI- BRATE TS-ZERO screen.

"Measured" is the current temperature read- ing, while "Applied" is a known temperature that will be applied for calibration purposes.

4.Set thermocouple simulator to 32 °F (0 °C), 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 ther- mometer, wait several minutes, and then use the and buttons to enter an Applied value that exactly equals the thermometer read- ing.

The calibration range is from 32 to 41 °F (0 to 5 °C). 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 ENTER to calibrate the TS-Zero Measured value to that of the Ap- plied value; after which the message “Good Calibration” should briefly appear followed by the CALIBRATE TS-SPAN screen.

TS-Span Procedure:

6.Set thermocouple simulator to 572 °F (300 °C), and then use the and buttons to enter an Applied value that exactly equals the setting of the simulator.

Alternatively: Submerge probe tip into a container of boiling water with a thermometer, wait several minutes, and then use the and buttons to enter an Applied value that exactly equals the ther- mometer reading.

The calibration range is from 175 to 625 °F (80 to 330 °C). An at- tempt to calibrate outside this range will cause the message “Applied Value High” (or Low) to appear at the bottom of the screen.

7.Wait until the Measured reading stabilizes, and then press ENTER to calibrate the TS-Span Measured value to that of the Applied value; after which the message “Good Calibration” should briefly appear fol- lowed by the CALIBRATION LIST screen being re-displayed.

5.6T-Air Calibration

This procedure first zeros and then spans the ambient-temperature chan- nel to known temperature values.

The use of an electronic thermocouple simulator is the preferred method of producing the desired calibration temperatures. Alternatively, ice and boil- ing water baths can be used.

Material Required:

•Thermocouple simulator (K-type)

-Range: 0 to 600 °F

-Accuracy: ±0.5 °F

•(Alternatively) Ice-water, boiling water, thermometer

TA-Zero Procedure:

1.Set thermocouple simulator to room temperature and plug its output 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 bot- tom 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 per Section 5.2.

3.Use the buttons to highlight T-Air, and then press ENTER to display the CALI- BRATE TA-ZERO screen.
