Gauge-Derived Moisture Offset
To allow the gauge to derive the moisture offset, you must
determine the
true moisture content
of a sample taken at the
measurement site using standard laboratory methods (for
example, oven drying, and so on), then take readings with the
gauge.
To use this method of determining the moisture offset, press
