ing water baths can be used.
Material Required:
•
Thermocouple simulator (K-type)
- Range: 0 to 300 °C
- Accuracy: ±0.3 °C
•
(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 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, power up the analyzer and display the CALI-
BRATION LIST screen per Section 5.2.
3. Use the buttons to highlight T-Air, and then press
ENTER
to
display the Calibrate TA-Zero screen.

“Measured” is the current temperature 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 ther-
mometer, wait several minutes, and then use the and but-
tons to enter an Applied value that exactly equals the thermometer
reading.
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.
