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.
“Measured”isthecurrenttemperaturereading,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 but-
tons to enter an Applied value that exactly equals the thermometer
reading.
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 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.
