Material Required:
•
Thermocouple
Simulator
(K-type)
Range: 0 to 600 °F
Accuracy:
±0.5 °F
Procedure:
Calibration
1.
With the analyzer turned off, first plug the simulator’s
K-type connec-
tor
into the T-STACK jack (Figure 3-2); then turn on the analyzer and
wait for its warm-up cycle to complete.
2.
Enter the Calibration Menu Screen per Section 5.3; then choose
TS-SPAN to span the analyzer’s stack temperature channel.
3.
Set the simulator to 575 °F (302 °C).*
4.
Wait until the MEASURED reading on the screen stabilizes. Then use
the
st
and
ENTER
keys to enter an APPLIED value that equals 575
°F
(302 °C).
Typical Calibrate TS-Span Screen During Calibration Procedure:
CALIBRATE TS-SPAN
MEASURED 595.0°F
APPLIED 0575.0°F
4.
Press the
RUN
key to calibrate the analyzer’s MEASURED value to
that
of the APPLIED value. At this time the Calibrate Menu Screen is
redisplayed.

The TS-Span calibration range is 518 – 626 °F (270 – 330 °C). Any
attempt to calibrate outside this range will cause the analyzer to
display the message BAD CALIBRATION ENTRY.
