Maintenance and Troubleshooting | 6-11

If the analyzer has been operating

for some time and you feel the oxy-

gen reading is inaccurate:

First check by running a known calibration gas to veri

fy the analyzer’s response. If the analyzer responds to

the calibration gas correctly, it indicates either leaking

or plugged plumbing.

If your analyzer doesn’t respond

properly to the calibration gas:

This may indicate a problem with the cell. Before

replacing the cell, put the analyzer through a primary

calibration and see if this improves the response of

the analyzer. If this doesn’t work, check for leaks or

plugged plumbing.

If this doesn’t solve the problem, replace the cell, then run another primary calibration.
