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.
8

4-5 Data Record ( Max., Min. reading )
* The data record function records the maximum and
minimum readings. Press the " REC. Button " ( 3-3, Fig.
1 ) to start the Data Record function and there will be a
" REC " symbol on the display.
* With the " REC " symbol on the display :
a)Press the " REC. Button " ( 3-3, Fig. 1 ) once, the
" REC Max " symbol along with the maximum value
will appear on the display.
If intend to delete the maximum value, just press
the " Hold Button " ( 3-4, Fig. 1 ) for a while, then
the display will show the " REC " symbol only &
execute the memory function continuously.
b)Press the " REC. Button " ( 3-3, Fig. 1 ) again, the
" REC Min " symbol along with the minimum value
will appear on the display.
If intend to delete the minimum value, just press
the " Hold Button " ( 3-4, Fig. 1 ) for a while, then
the display will show the " REC " symbol only &
execute the memory function continuously.
c)To exit the memory record function, just press the
" REC " button for 2 seconds at least. The display will
revert to the current reading.

5. OFFSET TEMP. ADJUSTMENT
Type K THERMOMETER
T
he instrument is fully calibrated to assure the high
quality measuring performance. Usually it is not
necessary to execute the Offset Temperature Adjustment
procedures, however the measured result could be
influenced by using different type of temperature probes.
Under such condition, customer can easily compensate
the temperature value by push button on the front panel.
However, in general conditions, customers are always
not recommended to execute the Offset Temperature
Adjustment Procedures without qualified calibration
equipment.
Offset Temp. Adjustment Procedure
1)Power on the instrument.
2)Set the function to the " Type K thermometer "
measurement, refer to page 6, Chapter 4-3.
3)Connect with a reliable temperature calibrator.
4)Adjust the calibrator and make it 0.0 output.
5)Press the " Hold Button " ( 3-4, Fig. 1 ) and " REC.
Button " ( 3-3, Fig. 1 ) at the same time for around 1
seconds, the upper display and lower display will show the
same value like
0.20.2
10

5)Under the " Hold Button " ( 3-4, Fig. 1 ) and " REC.
Button " ( 3-3, Fig. 1 ) be pressed condition, press
" , Button " ( 3-5, Fig. 1 ) to add 0.1 or press℃℉
" Function Button " ( 3-6, Fig. 1 ) to decrease 0.1 to the
upper digits.
0.00.2
6)When desired value available, release the fingers from the
" Hold Button " (3-4, Fig. 1) and "REC. Button " (3-3,
Fig. 1 ) to finish the Offset Temperature Adjustment
Procedures.
CONSIDERATION
The calibration point is highly recommended at
0.0 or normal ambient temperature. Please
never ever adjust the offset temperature over
this range (0.0 to normal ambient temperature).

6. AUTO POWER OFF DISABLE
The instrument has " Auto Power Off " function in order
to prolong battery life. If there are no buttons to be
pressed for around 10 minutes, the meter will power off
automatically.
Disable auto power off function by pressing the " REC.
Button " ( 3-3, Fig. 1 ) to get into the " Data Record "
function with a " REC " symbol on the display for long
period measurement.
7. RS232 PC SERIAL INTERFACE
The instrument has RS232 PC serial interface via a 3.5 mm
terminal ( 3-10, Fig. 1 ).
The data output is a 16 digit stream which can be utilized
for user's specific application.
A RS232 lead with the following connection will be required
to link the instrument with the PC serial port.

Each digit indicates the following status :
D15 Start Word
D14 4
D13 When send the upper display data = 1
When send the lower display data = 2
D12 & D11 Annunciator for Display
= 01℃= 02℉% RH = 04
D10 Polarity
0 = Positive 1 = Negative
D9 Decimal Point(DP), position from right to the left
0 = No DP, 1= 1 DP, 2 = 2 DP, 3 = 3 DP
D8 to D1 Display reading, D1 = LSD, D8 = MSD
For example :
If the display reading is 1234, then D8 to D1 is :
00001234
D0 End Word

Baud rate 9600
Parity No parity
Data bit no. 8 Data bits
Stop bit 1 Stop bit
8. BATTERY REPLACEMENT
1)When the left corner of LCD display show " ", it
is necessary to replace the battery. However, in-spec.
measurement may still be made for several hours after
low battery indicator appears before the instrument
become inaccurate.

2)Slide the " Battery Cover " ( 3-7, Fig. 1 ) away from the
instrument and remove the battery.
3)Replace with 9V battery ( Alkaline or Heavy duty type )
and reinstate the cover.
4)Make sure the battery cover is secured after changing the
battery.
