Bacharach 24-9351 Calibrate TA-Span, CALIBRATE TA-SPAN MEASURED 295.0C APPLIED 0300.0C, Procedure

PCA	Calibration
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.
