@ CALIBRATION CHECK KEY - This key,

(when pressed with the read key) checks the
meter calibration. It also displays the number
of readings in memory (up to 100), the aver­age, and the highest stored reading. It also
clears the memory.

# SPECIES KEY - Press to select the species

code for the wood you are testing. Species are
numbered from 1 to 48 and are listed on the
Species Code Chart on page 5. To scroll for­ward through the species codes keep the
species key pressed. To scroll backward press
the species key, release it and immediately
press the temperature key.

$ TEMPERATURE KEY - Press to set the wood

temperature. Press and immediately press the
Calibration Check the temperature key

@ to

toggle between (F and C). To increase the tem­perature setting keep the temperature key
pressed. To decrease the temperature, press
the temperature key, release it and immediate­ly press the species key.

CHECK CALIBRATION

Press the calibration check key @ and read key ! simul­taneously. Meter is in calibration if it displays 12%
(+ or - 0.2).

If you check the calibration and the meter does not display
12% it is likely an indication of a low battery. If this occurs,
replace the battery immediately with a new EverReady or
Duracell brand 9V. 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.

SET SPECIES

The J-2000 defaults to Species Code #1 - Douglas Fir - the
USDA standard and basis for all Delmhorst 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 key

#, and the meter will make the

necessary corrections.

hTo change species press the species key

#. The meter will

display the current species code for one second. Refer to
the Species Code Chart on page 5. Call our customer ser­vice team at 877-DELMHORST (335-6467) or e-mail
[e-mail] for assistance with any species or
wood-based material that is not included in the chart. It is
always helpful if you have the scientific name as well as
any common names for the species.

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.

A hard Reset is required if, after changing the battery, the
display is frozen. This is sometimes caused by the interrup­tion of contact between the battery and battery lead wire.
Resolve this as follows: Disconnect the battery. Press and
hold the Read key for 15 seconds. Release the Read key.
Press and hold the Check key for 15 seconds. Release the
Check key. Connect a fresh battery to the lead wire in a sin­gle action, making sure to align the poles properly and
without interrupting contact. If the display remains frozen,
repeat the procedure. If this procedure does not solve the
problem, refer to the Service for Your Meter section.

Meter Default Settings

Species - Douglas Fir
Temperature - 70ºF
Pin/Electrode - 4-pin (non-insulated)
Each of these parameters is programmed into the meter
and is user-selectable. Proper setting of each will insure
the most accurate readings.

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

key

$. The meter will display the current temperature for

one second.

hTo scroll forward through the temperature settings, press

and hold the temperature key

perature is displayed.

hPress the calibration check key

@ within one second and

release when you are in the desired mode.

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 “minus” 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
non-insulated pins. Insulated pins read lower than non-insu­lated 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 26­ES 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 pene­trate 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.

info. www.delmhorst.com

INFORMATION ABOUT
YOUR READINGS

Readings below 6% will be displayed as a numeric value,
(-##.#), but will not be added to the accumulated readings
in memory. Readings below 6% due to temperature and
species adjustments will be shown as a numeric value with no
minus sign. These readings will be added to the accumulated
total in memory and included in the statistical calculations.

Readings above 40% are always displayed as 999 and are
not added to the memory.

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 mem­ory is full.

When taking and storing readings for a specific wood
species, be sure to clear the meter's memory 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 key

@. The meter displays the number of accumulat-

ed 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 clear the memory press and hold the calibration check

key

@ 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 key @.

hWithin one second press the species key

#.

hThe meter will reset itself and display “170” to indicate the

meter is reset to default: Species #1 (Douglas Fir) at 70ºF,
followed by 444 (pin setting). All of the readings in memory
will be cleared.
