5.5 T-Stack Calibration

This procedure ﬁ rst zeros and then spans the stack-temperature channel

to known temperature values.

The use of an electronic thermocouple simulator is the preferred method of

producing the desired calibration temperatures. Alternatively, containers

of ice water and boiling water can be used.

Material Required:

• Thermocouple Simulator (K-type)

• Range: 0 to 600 °F

• Accuracy: ±0.5 °F

• (Alternatively) Ice-Water, Boiling Water, Thermometer

TS-Zero Procedure:

1. Set thermocouple simulator to room temperature and plug its

output into the T-STACK connector located at the bottom of the

analyzer.

Alternatively: Plug the probe’s

thermocouple into the T-STACK

connector located at the bottom of the

analyzer.

CAUTION: DO NOT attach the

probe’s gas hose to the analyzer’s GAS

port; otherwise water will be drawn

into the analyzer!

2. If not already done, turn ON

the analyzer and display the

CALIBRATION LIST screen per

Section 5.2.

3. Use the ▲▼ buttons to highlight

T-Stack, and then press ENT to

display the CALIBRATE TS-ZERO

screen.

“Measured” is the current

temperature reading, while “Applied”

is a known temperature that will be

applied for calibration purposes.
