BEFORE YOU BEGIN
Button Functions
!READ BUTTON - Reads the Percent Moisture
Content value (%MC), corrected for temperature
and species.
@CALIBRATION CHECK BUTTON - Checks
meter calibration. It also displays the average
of up to 100 accumulated readings; displays the
maximum stored reading; erases the readings.
#SPECIES BUTTON - Sets the species code
for the wood you are using. Species are numbered
from 1 to 48 and are listed on the Species
Code Chart. This button also acts as a scroll
key, depending on the function.
$TEMPERATURE BUTTON - Sets the wood
temperature and changes the temperature
mode (Fahrenheit or Celsius). This button also
acts as a scroll key, depending on the function.
CHECK CALIBRATION
Press the calibration check button @and read button !
simultaneously. Meter is in calibration if it displays 12%
(+ or - .2).
If you check the calibration and the meter does not display
12% it is likely an indication of a low battery. If this occurs,
change the battery immediately. Continued use with a low
battery may cause the meter to go out of calibration. If you
have a fresh battery and the instrument still does not indicate
a proper calibration, return it to DELMHORST for service.
See Service for your Meter section.
When the battery is removed and then reconnected, the
meter displays its software version for one second and then
turns itself off. After replacing the battery, you must reset
the meter as described in Resetting the Meter section.

SET SPECIES
The J-2000 defaults to Species Code #1 - Douglas Fir - the
USDA standard and basis for all calibrations. Because the
electrical characteristics of different species vary, all species
read differently at the same moisture content. For this reason
you need to adjust for species. If you are working with a
species other than Douglas Fir, set the species code using the
species button #, and the meter will make the necessary
corrections.
hTo change species press the species button #. The meter
will display the current species code for one second.
hTo scroll forward through the species list hold the species
button #while the current species code is displayed and
scroll to the species number desired.
hTo scroll backward through the species list, press and
release the species button #. Within one second, press
and hold the temperature button $. Continue to hold the
temperature button $and the species number will
decrease.
hWhen scrolling in either direction, release the button to
stop at your desired species.
The J-2000 can be used to test more than just wood. It will also
give a relative reading on plywood, OSB, particleboard and MDF
or can be fitted with a 26-ES slide hammer for specific
applications. Call Delmhorst at 1-877-DELMHORST or e-mail
[e-mail] for information on how to interpret the
readings for other materials.

COFI (code #48) and SPF-COFI (code #44) were developed by COFI.
When comparing readings between the model RDM-2/COFI or the
RDM-2S/COFI, used with type 26-E electrode with insulated pins,
and the J-2000, be sure both meters are set to 2-pin electrode
(insulated pins).
5

SET TEMPERATURE
The J-2000 defaults to a temperature of 70ºF. As wood
temperature increases, its electrical resistance decreases and
indicated moisture content rises. Lower wood temperatures
result in lower indicated moisture content. A correction is
necessary if the wood temperature is outside the range of
50ºF (10ºC) to 90ºF (32ºC). Set the temperature accordingly
and the meter will make the correction.
hTo change temperature press and release the temperature
button $. The meter will display the current temperature
for one second.
hTo scroll forward through the temperature settings, press
and hold the temperature button $while the current
temperature is displayed.
hTo scroll backward press and release the temperature
button $.Within one second, press and hold the species
button #.Continue to hold the species button #and the
temperature will decrease.
hWhen scrolling in either direction, release the button to
stop at the desired temperature.
Set Temperature Mode
hTo change from Fahrenheit to Celsius mode or Celsius to
Fahrenheit mode press the temperature button $.
hPress the calibration check button @within one second
and release when you are in the mode needed.
hThe meter will display the current temperature setting in
the new mode and will wait one more second until shutting
off so that you may change the temperature value as
described above.
If the meter is in Fahrenheit mode, the letter “F”will display
in the left-hand corner. If it is in Celsius mode, no letter will
appear in the display.
In the Fahrenheit mode, the temperature will change in
increments of 5ºF. In Celsius, the temperature will change in
increments of either 2ºC or 3ºC depending on its conversion
from Fahrenheit.
In the Fahrenheit mode, the temperature value will display in
whole numbers. In the Celsius mode, positive values will display
in whole numbers; negative values will display with a decimal
point and a “-”sign in the left-hand corner. (i.e.: -17.0)

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.

INFORMATION ABOUT
YOUR READINGS
Readings below 6% will be displayed as a numeric value,
(-##.#), and will not be added to accumulation. A reading
below 6% which is due to temperature and species adjustments
will be shown as a numeric value with no minus sign and this
reading will be added to the accumulation.
Readings above 40% are always displayed as 999 and are
not added to the accumulation.
The meter will accumulate up to 100 readings. After all 100
readings are stored it will not add new readings until the
memory has been cleared. It will also continue to display
the average of all 100 readings as a reminder that the mem-
ory is full.
When taking and storing readings for a specific wood
species, be sure to “clear”the meter before moving on to the
next species if you do not want to group all of the readings
together.
TO CHECK ACCUMULATED
READINGS
This feature allows you to view the total number of all
accumulated readings, the average of those readings, and the
highest stored reading.
hTo view the readings press and release the calibration
check button @. First the meter displays the number of
accumulated readings for one second, then the average of
those readings for two seconds. Then it displays the highest
stored reading for two seconds. The total “cycle”time is
five seconds.
hTo erase readings hold the calibration check button @
down for 5 seconds. All accumulated readings will be
erased and the meter will display “0”.
TO RESET METER
hPress and release the calibration check button @.
hWithin one second press the species button #.
hThe meter will reset itself and display “170”to indicated
Species #1 (Douglas Fir) at 70ºF. All of the readings in
memory will be cleared.

PIN TALK
There are two types of contact pins - uninsulated, which were
provided with your meter, and insulated. When using uninsulated
pins, push them in to the wood to their full length, if possible.
This will give you the highest measured reading. Insulated pins
read only at the tip and can be driven to a desired depth to
gather shell and core (gradient) information. Additional types
and lengths of both the insulated and uninsulated pins are
available for specific applications.
CARE OF YOUR METER
To keep your meter in good working order:
hStore your meter in a clean, dry place. The protective
carrying case provided is an ideal storage place when the
meter is not in use.
hChange the 9-Volt battery as needed. Continued use with a
low battery may cause the meter to go out of calibration.
hChange contact pins as needed. Keep contact pins hand
tightened.
hClean the meter and contact pins with any biodegradable
cleaner. Use the cleaner sparingly and on external parts
only. Keep cleaner out of the external connector &.
hRemove the battery if the meter will not be used for one
month or longer.
