SET PIN CALIBRATION
The basic factory calibration of the J-2000 is for use with
uninsulated pins – either the integral pins
^
or with an
optional external electrode, such as the #4-E. The difference
in readings between insulated and uninsulated pins is small
below 10% moisture content. The difference increases as
moisture content increases above 10%. When using an electrode
with insulated pins, such as the 26-ES, you can change the
calibration to compensate for this difference.
hTo change the pin setting, press and release the species
button
#
, then press the calibration check button
@
within one second.
hThe meter will display the current pin calibration as either
222 for insulated or 444 for uninsulated pins.
hIf you continue to hold the calibration check button
@
,
the meter will change pin calibration. The new calibration
will remain in “memory” until you change it again, or
you remove the battery.
TAKING A READING
The contact pins
^
provided are best for stock up to 6/4.
On stock over 6/4 or for hardwoods over 4/4 we recommend
using a remote probe such as the 26-ES ram-type electrode.
Mount the 26-ES directly to the external connector
&
.
See additional information under the Pin Talk section.
hRemove the protective cover to expose the pins. Check
that the contact pins
^
are firmly hand tightened.
hTo take a reading, align the contact pins
^
parallel to
the grain and push them to their full penetration into the
wood, if possible. Insulated pins read only at the tip and
can be driven to the desired depth.
hPress the read button
!
and read the moisture content
on the meter scale. The meter displays the %MC for
two seconds.
hTo add a reading to the sum of all the previously stored
readings, release the read button
!
within 2 seconds.
