Checking Calibration
After you have cleaned the chamber and other parts of
your WP4C, it is important to check the instrument's per-
formance in order to correct for any calibration change
that may have occurred during cleaning procedures.
Check the calibration of your instrument by measuring the
water potential of the KCl standard. If a change has
occurred, refer to chapter 5 for directions on how to reca-
librate. If, after adjusting calibration your instrument is
still not reading samples correctly, contact Decagon for
technical support.
