4. GENERAL MEASURING
PROCEDURE
The meter default value are :
*The temperature reading unit is .℃
*The sampling time of data logger function is
2 seconds.
4-1 Humidity and Temperature measurement
1)Plug the " Probe Plug " ( 3-10, Fig. 1 ) into the " Probe
Input Socket " ( 3-9, Fig. 1 ).
2)Power on the meter by pressing the " Power Button "
( 3-2, Fig. 1 ), the LCD shows the unit " %RH " & " "℃
at the same time and measured value will show on
the display ( upper display is Humidity value, the
lower display is the temperature value ) .
3)The meter Temp. display unit is defaulted to " ". If℃
intend to let the meter's temperature unit default to " "℉
, then please refer section 5-1 ( page 11 ).
4-2 Dew point measurement
The procedures of " Dew point measurement " are same
as the above " 4-1 Humidity and Temperature
measurement " except select the " Dew point " function
by pressing the " Function Button " ( 3-5, Fig. 1 ) once,
the LCD will show the unit " DEW " & " ( or ).℃℉
The upper display show the Dew point value, the lower
display show the temperature value.
6
4-3 Data Hold
During the measurement, press the " Hold Button " ( 3-3,
Fig. 1 ) once will hold the measured value & the LCD will
display a " HOLD " symbol.
* Press the " Hold Button " once again will release the data
hold function.
4-4 Data Record ( Max., Min. reading )
* The data record function records the maximum and
minimum readings. Press the " REC Button " ( 3-4, Fig.
1 ) once 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 " ( 3-4, 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 " ( 3-3, Fig. 1 ) once, then the
display will show the " REC. " symbol only & execute
the memory function continuously.
b)Press the " REC Button " ( 3-4, 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 " ( 3-3, Fig. 1 ) once, 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.

4-5 Data Logger
The data logger function can save 1000
measuring data ( Humidity/Temp. value or
Dew point/Temp. value )
The data logger procedures are as following :
a)Press the " REC Button " ( 3-4, Fig. 1 ) once to
start the Data Record function and there will be a
" REC. " symbol on the display.
b)Auto Data Logger ( Sampling time can select to
1, 2, 10, 30, 60, 600, 1800, 3600 seconds )
Press the " Logger Button " ( 3-6, Fig. 1 ) once to
start the Data Logger function. The upper display
will show the sampling time in seconds ( For
example, 1, 2, 10, 30, 60, 600, 1800, 3600 ) once a
while then revert to the normal display screen. In
the same the top display will show the marker " A ",
the marker " A " will be flashed per sampling time.
Now the Date Logger function is executed.
Manual Data Logger ( Sampling time set to 0
second )
Press the " Logger Button " ( 3-6, Fig. 1 ) once will
save the data one time into the memory, at the
same time the marker " A " will be flashed once
a while.
