BEFORE YOU BEGIN
The RC-1E features a three range analog scale (A, B & C) that reads wood
moisture content directly as a percentage of the dry weight in the wood. The
scale covers a range of 6% to 80%. The C scale on the meter is also a 0-100
relative scale and is used for relative readings on non-wood materials.
*NOTE:
The numbers in parentheses refer to the RC-1E/SP
CALIBRATION CHECK
To check the calibration, first put the selector switch on the “B” scale. Push the
“ON/OFF” switch to the “ON” position and hold. The meter is in calibration if it
reads “20%” ±1% (23%)±1% or within the green band on the “B” scale. If the
needle does not read within the green band on the “B” scale, it is likely an
indication of low battery power. If this occurs, change the battery immediately.
