MODEL 300 COMBUSTION ANALYZER
Instruction 24-9223 2-7
2.6 SENSOR CHECKS
A new analyzer has all sensors installed and calibrated at the factory;
however, you should ensure that the sensors are still in calibration before
performing your first combustion efficiency test.
To check that the CO sensor is operating, follow the calibration procedure
described in Section 4.3 “CO Span Calibration;” however, do not remove
the control panel or make adjustments as instructed. The control panel
needs to be removed only if the CO calibration pot needs adjustment.
