L610 Moisture Meter
In response to today’s growing need for timely, accurate
moisture monitoring information and record keeping,
Wagner introduces the L610 Digital Recording Moisture
Meter. This remarkable instrument combines Wagner’s
unique “Wood-Friendly” electromagnetic scanning with
Wagner’s latest microcomputer technology.
•Stores and displays up to 50 user-selected species
adjustments by name.
•Stores up to 500 separate moisture readings.
•Stores readings in up to 5 groups.
Using non-volatile memory, stored readings are retained

500-61001-001 Rev. D Page 5of 30
even when the batteries are removed. A backlit LCD
display features a 2-line, 32 character display. Function
buttons and scroll arrows operate a menu system that
guides the user step-by-step through the selecting,
storing and reporting process. The meter has auto-shut-
off to extend battery life. It can operate accurately in
virtually every wood drying and processing environment.
Like all Wagner handmeters, it is virtually unaffected by
wood temperature.**

Getting Started
This sections informs you about
•Turning on the meter
•Moisture readings
•Storing a reading
•What is a group
•Viewing statistics
•The menu system
•Changing species
Before you begin, make sure your hand-meter has a
freshset of batteries.
Turning on the meter
Turn on the meter by pressing theSTORE button for one
second. The display will momentarily show the model,
software version, and revision numbers. Your meter is
now ready to take moisture readings.
Moisture readings
Take moisture readings by pressing the bottom of the
meter to the wood surface. The first line of the display
shows the species for which the meter is calibrated. The
second line shows the reading in percent moisture
content.
Storing a reading
While pressing the bottom of the meter to the wood
surface at the location of interest, press theSTORE button
to save that reading in a group.
What is a group?
A group is a set of readings that belong together. You
determine which readings belong together. Switch to
another group by first pressing the GROUP button. Press
the ARROW buttons to select a different number. Press
the STORE button to activate the selection. The active
group number is shown in the bottom right corner of the
display.
Viewing statistics
Statistical values such as mean, standard deviation,
highest reading, and lowest reading are calculated on
individual groups. They may be accessed for viewing by
using the menu system.
The menu system
For example, to view the mean and standard deviation
values for the active group, press theMENU button to
activate the main menu. Press the ARROW button to
scroll through the menu until the menu item Mean/Std is
displayed. Press the STORE button to activate the menu
item.
Changing species
If the meter is not set to the species you are measuring
change it using the menu system. See the section
“Factory Species List” for a complete list of available
species. If your species is not listed, you may customize
a species as outlined in the section “Changing Species.”

500-61001-001 Rev. D Page 7of 30
Taking Measurements
In order to take correct moisture content measurements,
ensure that the meter’s specific gravity (species) setting
is the correct one for your species of wood as listed in the
Species Setting Table or Species lists.
Be sure to press down firmly on the center of the meter
with approximately 3 pounds of force to ensure good
sensor plate contact with the wood surface. This is
especially important on rough-sawn lumber. Do not take
readings where there is a noticeable defect or knot in the
lumber.
If there is visible surface moisture or water, wipe off any
excess, and let the surface of the wood dry-out for a
couple of minutes, then take the reading. If possible, turn
the board over and measure the other side. If the
thickness of the piece is greater than 3 inches, it is a
good idea to take measurements on both sides.
Ensure that there is nothing (especially your hand or
metal) under the material you are measuring. The actual
moisture sensing area is a 2 ½ inch by 2 ½ inch
rectangle on the meter’s backside (opposite side of the
panel meter). In order to take a valid measurement, this
sensing area must be completely covered with the wood
you are measuring. If the sensing area is not completely
covered, your moisture reading will be inaccurate.
Additional meter corrections may be necessary if you are
measuring Raft Wood (salt water permeated), or lumber
treated with Copper, Chrome, Arsenic (CCA), or
Ammonical, Copper, Quantenary (ACQ). Contact Wagner
Technical Services for further information for these
applications.
Meter Storage
Meter Storage
For a long service life, it is important to store your meter
properly. Avoid excessively hot or cold locations. Do not
store the meter in an area with excessive electro-
magnetic interference, such as near an electric motor, or
where it could be crushed, such as in front of a forklift. Do
not leave the meter in an operating kiln during the drying
cycle.

Turning ON the Meter %MC Readings Storing Readings
OPERATION
To turn ON the Meter, press the
STORE button for one second.
The Meter will turn OFF after 1 minute
of inactivity.
Inactivity means no change in
moisture readings or button presses.
The Meter takes continuous %MC
readings and puts them on the display.
When a reading is below 5%, the first
line shows the current species and
group field label. The second line
shows the current %MC reading and
group number. When a reading is
above 5%, the first line becomes a bar
graph representing the current %MC
reading.
When a valid reading is stored, the
second line will display a message
stating that it was stored as sample #
xxx. When attempting to store an
invalid reading, a message will state
the reading was too low and last
sample # xxx.

Checking Calibration
Calibration is factory set. It may be checked by using a
Wagner Calibration Verification Block (CVB) (P/N: 840-
60130-002). Use only to verify L610 factory calibration is
within tolerance limits. If calibration is out of tolerance,
return L610 to factory or repair depot for re-calibration.
Never adjust L610 to this device. Protect CVB from
direct sunlight. Store in cool dry place. Follow these
steps for checking calibration.
1. Enter the Calibration menu item.
2. Hold the meter in mid air so the bottom is several feet
from any object. The correct reading for air is .0
%MC. If the reading is outside the range, -2 to 2
%MC, the unit is out of calibration.
3. Place the CVB, rubber feet down, on a metal surface:
such as a file cabinet, a piece of sheet metal, etc.
4. Orientate the long axis of the handmeter with the long
axis of the CVB. Press the handmeter sensor in the
center of the CVB and observe the reading. The
correct reading is 17.5 %MC. If the reading is outside
the range, 15.5 to 19.5 %MC, the unit is out of
calibration.
Warning—There are two (2) hole plugs located on either
side of the L610 handle. Do not remove these plugs
because the adjustments below them are factory set and
should not be adjusted by the customer. If adjustment is
attempted, the unit will not be in calibration and will
require factory re-calibration. Also if adjustment is
attempted, warranty will be voided.

500-61001-001 Rev. D Page 16of 30
Technical Notes
Readings and Groups--The L610 can store up to 500
readings in up to 5 groups. Groups are numbered 0 to 4
and can be selected at random. There is no limit to the
number of readings per group as long as the total
readings of all groups do not exceed 500.
Automatic Menu Escape--When in the menu system
and 15-seconds of no key presses, the Meter will
automatically return to the %MC Reading mode ready to
store the next reading in the current group.
Repeat Key--If a key (button) is held down for more than
one (1) second, then the key pressed is repeated at a
rate of one (1) repeat each second. After 5 repeats the
rate doubles and after an additional 5 repeats the rate
doubles again. Use this feature to scroll through long list
of species or readings.

500-61001-001 Rev. D Page 17of 30
Factory Species List
The L610 has a factory default of 50 species. The
specific gravity (SG) and name may be adjusted from the
Species menu item. This allows you to tailor the Meter
calibration to a species not listed.

L610 SPECIES ADJUSTMENT
In our quest to continually upgrade our products and
services, it has come to our attention that some of the
lesser used species adjustment values (SG) stored in the
default list of L610 hand-meter are not the correct values.
If you use any of the following species in your operation,
please store the new values to ensure the greatest
accuracy of your hand-meter. Should the internal lithium
battery in the meter fail, or the meter is sent in for
service, you will have to re-enter the appropriate values.
Please place this bulletin in the back of your L610
manual.
