The use of an electronic thermocouple simulator is the preferred method of
producing the desired calibration temperatures. Alternatively, containers of ice
water and boiling water can be used.
6.5.1. Material Required
•
Thermocouple Simulator (K-type):
Range:
0 to 300 °C
Accuracy: ±0.3 °C
•
(Alternatively) Ice Water, Boiling Water, Thermometer
6.5.2. TS-Zero Procedure
1. Set thermocouple simulator to room temperature and plug its output into
the T-STACK connector located at the bottom of the analyzer.
Alternatively:
Plug the probe’s thermocouple into the
T-STACK connector located at the bottom of the analyzer.
CAUTION:
DO NOT attach the probe’s gas hose to the
analyzer’s GAS port or water will be drawn into the
analyzer!
2. If not already done, turn ON the analyzer and display the
CALIBRATION LIST screen (refer to Calibration on page 66).
3. Use the ▲▼ buttons to highlight T-Stack, and then press
ENT
to
display the CALIBRATE TS-ZERO screen.
NOTE:
“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 thermometer, wait several minutes, and then use the
▲▼ and ◄► buttons to enter an applied value that exactly
equals the thermometer reading.
NOTE:
The calibration range is from 0 to 5 °C (32 to
41 °F). Calibrating 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
ENT
to
calibrate the TS-Zero Measured value to that of the applied value; after
which the message “Good Calibration” should briefly appear followed by
the CALIBRATE TS-SPAN screen.
