Temperature Correction; Care Of Your Meter - Delmhorst C-2000 Owner's Manual

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
110°F
50°F

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.
