5.7 Calibrate TA-Span
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-AIR 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
TA-SPAN to span the analyzer’s room-air/primary-air temperature
channel.
3. Set the simulator to 212 °F (100 °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 212 °F
(100 °C).
Typical Calibrate TA-Span Screen During Calibration Procedure:
CALIBRATE TA-SPAN
MEASURED 209.0°F
APPLIED 0212.0°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 TA-Span calibration range is 194 – 230 °F (90 – 110 °C). Any
attempt to calibrate outside this range will cause the analyzer to
display the message BAD CALIBRATION ENTRY.
