a. For temperature measurements,the display shows
the present environment temperature directly.
b. For moisture measurements, Take off probe shield
and press the pins of two sides with fingers , Insert the
pins into the object approx. 5mm, which display the
containing water of the object.
Automatic Power-Off Feature
If you don’t operate the instrument (or the reading does
not change)for about 5 minutes,the instrument will turn
off automatically.
Data Hold
a. Only the moisture measurement status, press the
HOLD key to lock the measured values
b. For temperature measurements, press the HOLD key
to be useless.
LED indications for moisture and related settings
a. This apparatus can indicate the moisture of the objects
to be measured through the lighting of the color LED.

There are two values for controlling the warning of LED
light, namely AL1 and AL2. The factory defaults of wood
moisture are: AL1=13, AL2=18, and for Material moisture,
they are: AL1=0.3, AL2=0.8, If the measured value is
less than 13, the green indicator will be turned on. If it is
higherthan 18, the red indicator will be turned on. If it is
between 13 and 18, the yellow indicator will be turned on.
The user can set these two values in light ofhis own
conditions
b. Set the warning value
(1) To set the value of AL1, press the “SELECT” button
and hold it till “AL1” appears(it takes about 3 seconds),
The use “hold ▲” or “℃/℉▼” to change the number to
the value you desire. To exit the seting mode,press
“select” again.
(2) To set the value of AL2, press the “SELECT”
button and hold it till “AL2” appears(it takes about 5
seconds), to change the number, Ditto operation.

1. Keep the instrument dry.
2. Keep the probe clean.
3. Keep the instrument and battery out of reach of
infant and child.
4. Some factors (such as material type and
temperature can affect moisture measurement result and
may make it necessary to correct the displayed
value.Don’t use the instrument in the case of inspections
or for reference purposes.
5. When the symbol “ ” appears,the batteries are low
and should be replaced.
Ensure that battery polarity connections are correct
