WP4C 9 CLEANING AND MAINTENANCE
9.3 Checking Calibration
After you have cleaned the chamber and other parts of your WP4C, it
is important to check the instrument performance 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 recalibrate. If, after adjusting
calibration your instrument is still not reading samples correctly,
contact METER for technical support.
