5.5 T-Stack Calibration

This procedure first zeroes 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, ice and

boiling water baths can be used.

Materials 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 the 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 con-

nector located at the bottom of the analyzer. 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 CALI-

BRATION LIST screen per Section 5.2.

3.Usethe▲▼buttonstohighlightT-Stack,

and then press ENTER to display the CALI-

BRATE TS-ZERO screen.

"Measured" is the current temperature read-

ing,while"Applied"isaknowntemperature

that will be applied for calibration purposes.

4. Set thermocouple simulator to 32 °F (0 °C),

and then use the and buttons to en-

ter an Applied value that exactly equals the

setting of the simulator.
