Meter functions:
MC READ:
The RDM-3 operates on the principle of electrical resistance - it uses wood as
the element in a circuit by driving two electrode pins into it. This method is
effective because moisture is an excellent conductor of electricity and wood is an
effective insulator. Besides the moisture content itself, the factors that affect the
accuracy of the readings are the wood temperature and species. To insure
reliable results, set the meter to the appropriate temperature and species
parameters before taking readings.
The meter is able to store MC measurement results for review, statistical analysis
or download to a PC. In order to allow the user to better keep track of stored
data, the meter organizes MC readings in groups called JOBS.
o A reading cannot be taken or stored without being part of a job.
There are no limitations to a job size, other than those imposed by
storage memory limits.
o The meter supports up to 98 different jobs at any one time.
o The meter imposes strict boundaries among existing jobs. All
operations on stored data can only be performed on the job
selected.
o The meter restricts each job to one species. Only readings taken
from the same species can belong to a specific job. More than one
job can be defined with the same species.
