Calibration
5.6 Calibrate TA-Zero
Material Required:
•
Thermocouple Simulator (K-type) Range: 0 to 600 °F
Accuracy: ±0.5 °F
Procedure:
PCA
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-ZERO to zero the analyzer’s room-air/primary-air temperature
channel.
3. Set the simulator to 32 °F (0 °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 32 °F
(0 °C).
Typical Calibrate TA-Zero Screen During Calibration Procedure:
CALIBRATE TA-ZERO
MEASURED 37.0°F
APPLIED 0032.0°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-Zero calibration range is 0 – 5 °C (32 – 41 °F). Any attempt to
calibrate outside this range will cause the analyzer to display the
message BAD CALIBRATION ENTRY.
