Temperature Correction
The basic calibration assumes the cotton temperature to be
70°F. For best accuracy, apply a temperature correction if
the cotton temperature is outside the range of 60°F to 80°F.
Make a correction of approximately 1.0% for every 20° F.
The meter will read higher than the actual moisture content
as cotton temperature increases, and will read lower as cot-
ton temperature decreases.
Example:
At 70°F, a reading of 7% indicates actual %MC of 7%. At
varied temperatures, meter readings will vary as follows:
Cotton Temperature Meter Reading Actual %MC
110°F 9.0% 7%
50°F 6.0% 7%
CARE OF YOUR METER
To keep your meter in good working order:
hStore your meter in a clean, dry place. The protective
carrying case provided is an ideal storage place when
the meter is not in use.
hChange the 9-Volt battery as needed. Continued use with a
low battery may cause the meter to go out of calibration.
hClean the meter, contact pins, and probes with any
biodegradable cleaner. Use the cleaner sparingly and on
external parts only. Keep the cleaner out of the external con-
nector.
DO NOT IMMERSE THE METER OR ANY ELEC-
TRODE IN WATER.
hRemove the battery if the meter will not be used for one
month or longer.
