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.

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.
