INSIGHT

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.

5.6 T-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.
