25. See the list of acceptable values in table 6-2 below to interpret linearity readings.
a. Values that are ± 5% of specified tolerance limits indicate good membranes.
b. Values that are out of tolerance indicate an aging enzyme membrane.
c. If readings are out of tolerance limits, recalibrate and repeat all the steps above to confirm.
d. If the reading is still out of tolerance, refer to the Troubleshooting Section.

Sample Preparation
A variety of sample types can be analyzed with the 2900 Series. Generally, the only sample preparation that may be
required is dilution of the sample to bring the substrate concentration within the linear range of the instrument. (see
Section 8 Chemistry Setup for the working range of each chemistry).
Neither color nor turbidity interferes with measurements.
Small particles do not affect the reaction in the sample module that houses the probes, but samples with particles large
enough to clog the sipper should be avoided.
