Maintenance and troubleshooting
Maintenance:
The model 210BR is virtually maintenance free other than for periodic calibration and occasional sensor
replacement.
Periodic Calibration:
The analyzer should be calibrated about once every month to obtain the best accuracy. The sensor typically
declines in sensitivity by about 1% per month, so a monthly calibration is usually satisfactory. Use in a
particularly aggressive environment may degrade the sensor faster: in this case calibrate more often.
You can see the calibration history using the user interface as described in the previous section of this
manual.
Sensor Replacement:
This should be done based on the Span Factor feature, rather than as a response to a dead sensor. See the
chart below for recommended sensor replacement.
