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.
5.6 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.
