• Optional NOx and/or SO

concentrations are displayed on the

auxiliary panel.

• Optional clock displays the current time.

NOTE: It’s normal for the Display Mode Indicators to occasion-

ally blink due to the complexity of the efficiency calculations.

panel-mounted filter/trap.

WARNING!

The liquid within the filter/trap bowl may be hot and mildly

acidic.

If water begins to approach the trap’s filter element, press RUN key to

stop test. Remove filter/trap and empty its bowl (Fig. 3-1). When

replacing the bowl, be sure its O-ring is properly installed, and the

shield is properly oriented – improper installation can allow air to leak

into gas sample and reduce accuracy of efficiency calculation. Reinstall

filter/trap and press RUN key to resume testing.

9. To end an efficiency test, press RUN key to stop pump. All testing

information is stored until analyzer is turned off or recalibrated.
