Bacharach Fyrite INSIGHT Instructions Manual page 59

To improve the accuracy of the CO reading, we suggest that if the analyzer
will be primarily used for flue gas testing, then calibrate using 500 ppm
CO. If the analyzer, however, will be primarily used for ambient testing,
then calibrate using 100 ppm CO.
Procedure:
1. If not already done, power up the analyzer and display the Calibra-
tion List screen per Section 5.2.
2. Use the
play the Calibrate CO screen.
"Measured" is the current CO reading, while "Applied" is a known
CO level that will be applied for calibration purposes.
3. Attach a 500 ppm CO cylinder to the regulator of the calibration
fixture.
4. Use the
equals the concentration stamped on the CO cylinder.
The calibration range is from 20 to 1,000 ppm. An attempt to
buttons to highlight CO, and then press ENTER to dis-
and buttons to enter an Applied value that exactly
