SET PIN CALIBRATION
The basic factory calibration of the J-2000 is for use with
non-insulated pins. Insulated pins read lower than non-insu-
lated ones. The difference is small below 10% MC but
increases as the moisture content increases above 10%.
When using an electrode with insulated pins, such as the 26-
ES hammer electrode, you can change the calibration to
compensate for this difference.
hTo change the pin setting, press and release the species
key
#, then press the calibration check key @ within
one second.
hThe meter will display the current pin calibration as either
222 for insulated or 444 for non-insulated pins.
hIf you continue to hold the calibration check key
@, the
meter will toggle between 222 and 444.
TAKING A READING
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 key
! 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 key
! within 2 seconds.
The non-insulated contact pins on the top of the meter pene-
trate max 5/16in. and may be used on wood up to 1-1/2 to
2in. thick. Push the pins into the wood to their full penetration
for best accuracy. For thicker wood and hardwoods over 4/4,
use the 26-ES hammer electrode with insulated pins. These
pins (no. 496), may be used on wood up to 5-6in. thick.
Connect the electrode to the input connector on the top of the
meter
&. Contact our customer service team for more infor-
mation on other available pins for your application.
Insulated pins offer the advantage of taking measurements
at various depths since the reading is made at the point in
the wood where only the non-insulated tips of the pins make
contact. This is especially useful when drying lumber since
reliable shell and core readings are essential to producing
high quality lumber.
