4. MEASURING PROCEDURE
4-1 Humidity content measurement
1)Plug the " Probe Plug " ( 3-12, Fig. 1 ) into the
" Humidity Probe Input Socket " ( 3-9, Fig. 1 ) of the
meter.
2)Power on the meter by pressing the Power Button ( 3-2,
Fig. 1 ).
3)Take the " Protection cover " ( 3-16, Fig. 1 ) away from
" Sensing head " ( 3-15, Fig. 1 ).
4)Penetrate the " Sensing head " ( 3-15, Fig. 1 ) along with
" Probe main body " ( 3-14, Fig. 1 ) into the
measurement materials ( such as Grain, Corn, Rice.
Cotton, Paper...), refer to Fig. 2. The meter's
display will show the Humidity content and the Temp.
value of the inner testing material.
Remark :
During the measurement Press the " , Button " ( 3-5,℃℉
Fig. 1 ) to select the temperature unit.
5)After finish the measurement, slide the " Protection
cover " ( 3-16, Fig. 1 ) into the " Sensing head " ( 3-15,
Fig. 1 ).

Remark :
There is built the " Filter " on inner of the " Sensing
head " ( 3-15, Fig. 1 ). After the probe is used for a long
period and find the humidity response time change to
long time, it should change the unit of " Sensing head
with inner filter " ( optional accessory, Model ; MS-71HEAD ).
4-2 Dew point measurement
The procedures of " Dew point measurement " are same
as the " Hygrometer measurement ", except select the
" Dew point " function by pressing the " Function Button
"(3-6, Fig. 1), the LCD will show the unit " DEW " & " ℃
( or ).℉
4-3 Type K thermometer measurement
1)Take out the humidity probe away from the " Humidity
Probe input Socket " ( 3-9, Fig. 1 ).
*
If not take out the humidity probe, the type K
measurement will be still available.
2)Plug the optional type K temperature probe into the
" Temp. Probe input Socket " ( 3-8, Fig. 1 ). Press the
" Function Button " ( 3-6, Fig. 1 ) once a while until the
display showing the unit of " " ( or ) only.℃℉
4-4 Data Hold
During the measurement, press the " Hold Button " ( 3-4,
Fig. 1 ) will hold the measured value & the LCD will
indicate a " HOLD " symbol on the display.
* Press the " Hold Button " again to release the data hold
function.
