Procedure:

NOTE: The unit-of-measure for pressure is selected per Section 3.5.3. In

the following procedure inwc is selected, but note that any unit-

of-measure can be used for calibration purposes.

Figure 5-1 Pressure Sensor Calibration Equipment

1. Assemble the pressure sensor calibration equipment as shown in

Figure 5.1, but DO NOT connect the analyzer to the calibration

equipment at this time.

2. If not already done, power ON the analyzer and display the CALI-

BRATION LIST per Section 5.2.

3. Use the ▲▼ buttons to select PRESSURE

and then press ENTER to display the CALI-

BRATE PRESSURE screen.

"Measured" is the pressure value currently

being detected by the pressure sensor, while

"Applied is a known value of pressure that

will be applied for calibration purposes.

4. With both the -ΔP and +ΔP ports open to the atmosphere, observe

that the current Measured pressure reading should be 0.00 ± 0.01

inwc. If necessary, zero the pressure sensor per Section 4.6 then

repeat steps 2 through 4.

5. Connect the hose from the manometer to the +ΔP port and apply a

negative pressure to this port by adjusting the bellows for a manom-

eter reading of -4.00.

6. Use the ▲▼ buttons to enter an Applied value that exactly equals

the manometer reading.

The calibration range is from -6 to -2 inwc (-15 to -5 mb). An attempt

to calibrate outside this range will cause the message "Applied Value

High" (or Low) to appear at the bottom of the screen.

7. Wait until the Measured reading stabilizes,

and then press ENTER to calibrate the pres-

sure sensor's Measured value to that of the

Applied value. The message, "Good Calibra-

tion" should briefly appear, followed by the

CALIBRATION LIST screen.

8. Remove calibration equipment.

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!
