Operational Instructions — MMC 205
On/Off/Species Button:
When the meter is Off, momentarily pressing and releasing this button will cause the
meter to turn On, and briefly display the firmware version, then enter Measurement
mode. When the meter is in Measurement mode, and the button is momentarily pressed
and released, it will display the species setting value. Press and release the button again to return to
Measurement mode.
To turn Off the meter from Measurement mode only, press the On/Off/Species button for 3 seconds and
then release. The meter will also turn itself off automatically when not in use as described in the auto-
shutdown section.
Species Setting:
The species setting can be changed to compensate for a variety of wood species. When measuring another
species with a Specific Gravity (SG) other than the factory default setting of 0.50 SG, the species setting
needs to be changed. Refer to the Species Setting Tables included with your meter to locate the correct
species setting for your wood. If your species setting is not listed, contact Wagner Meters. The values
entered into the MMC 205 meter omit the decimal point, so for example the Douglas Fir value of 0.48
would be “48” when programming the Species Setting Value.
When the meter is in Measurement mode, momentarily pressing and releasing the On/Off/Species
button will cause the display to show the current specific gravity setting. Press the button a second time for 3
seconds and release to enter CHANGE SPECIES MODE, or momentarily press and release the button to
return to Measurement mode.
When CHANGE SPECIES MODE has been selected, a blinking colon symbol (:) will appear on the
display. Momentarily pressing the On/Off/Species button again will increment the selected specific
gravity value by 01. The value will go as high as 70, then will wrap around to 30 and continue
incrementing. When the desired setting has been reached, press button for 3 seconds and release to store
the value and return to Measurement mode.
Your commonly used species setting values can be written on the meter overlay decal in the space
provided using a pencil or non-permanent marker, and erased with a swab dipped in isopropyl alcohol.
Avoid using a permanent marker because staining of the decal may occur.
