Calibration

5.4 T-Stack Calibration

This procedure first 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 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 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 read- ing, while “Applied” is a known temperature that will be applied for calibration purposes.

The calibration range is from 32 to 41 °F (0 to 5 °C). An attempt to calibrate outside this range will cause the message “Bad Calibration Wrong CAL Entry” to appear in the following step.
