Initial Setup
3.12 Print Pressure Selection
Select whether to print or not print the pressure
measurement on the combustion test printout as
follows:
1. Display the MAIN MENU by pressing the
MENU (F2)

ESC
until
MENU appears above
F2
.
2. Use the
buttons to highlight SETUP, and

Sensor Calibration
This procedure spans the optional sulfur dioxide sensor to a known
gas level.
Material Required:
Calibration Kit, P/N 24-7059
Gas Cylinder: 100 ppm SO
2
in Nitrogen, P/N 24-1158
Procedure:
1. If not already done, turn ON the analyzer
and display the CALIBRATION LIST screen
per Section 5.2.
2. Use
the buttons to highlight SO
2
, and
then press
ENT
to display the CALIBRATE
SO
2
screen.
“Measured” is the current
SO
2
reading, while
“Applied” is a known
SO
2
level that will be
applied for calibration purposes.
3. Attach a 100 ppm SO
2
cylinder to the regu-
lator of the calibration fixture shown in
Figure 5-2 on Page 5-14.
4. Use
the and buttons to enter an
Applied value that exactly equals the concen-
tration stamped on the SO
2
cylinder.
The calibration range is from 9 to 1,800 ppm.
An attempt to calibrate outside this range will
cause the message “Bad Calibration Wrong
CAL Entry” to appear in the following step.
5. Adjust regulator for a flowmeter indication of approximately 2 SCFH.
Wait until the Measured reading stabilizes (approximately 3 minutes),
and then press
ENT
to calibrate the SO
2
Measured value to that of the
Applied value. The message “Good Calibration” should briefly appear
followed by the CALIBRATION LIST screen being re-displayed.
If the sensor’s output is low, but still usable, then the message “Good
Calibration WARNING Low Sensor” will appear. The sensor will now
