Instruction 24-9351
PCA
5.5 Calibrate TA-Span
Material Required:
• Thermocouple Simulator (K-type) Range: 0 to 300°C
Accuracy: ±0.3°C
Procedure:
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 warmup cycle to complete.
2. Enter the Calibration Menu Screen per Section 5.3; then choose
TA-SPAN to span the analyzer’s stack temperature channel.
3. Set the simulator to 300° C (572° F).*
4. Wait until the MEASURED reading on the screen stabilizes. Then use
the st and keys to enter an APPLIED value that equals 300 °C
(572 °F).
Typical Calibrate TA-Span Screen During Calibration Procedure:
CALIBRATE TA-SPAN
MEASURED 295.0°C
APPLIED 0300.0°C
4. Press the key to calibrate the analyzer’s MEASURED value to
that of the APPLIED value. At this time the Calibrate Menu Screen is
redisplayed.
* The calibration range for this screen is 270 – 330 °C (518 – 626 °F).
Any attempt to calibrate outside this range will cause the analyzer to
display an error message.
