Quick Start Guide
9. Follow the instructions on the display, manually applying calibration
gases to the calibration port.
Emerson recommends applying 0.4 percent and 8.0 percent O
SCFH.
10. After the calibration is finished, press Left and use the Up and Down
buttons the check the current and previous ten calibration logs.
After completing the procedure, the software calculates new calibration
values and determines whether they meet an acceptance criteria. If
successful, the new calibration values automatically replace the previous
values. In the event the calibration values do not meet the accepted
performance criteria, the existing calibration values remain in effect, and
Emerson recommends replacing the probe.
CAUTION
Many combustion processes operate at a slight negative pressure (draft
pressure) and can draw ambient air down the cal gas lines and into the
sensing cell, causing a false elevated oxygen reading.The same phenomenon
is possible if the calibration gas hoses become degraded or loose.
Ensure that you replace the calibration cap tightly after completing
calibration.
