4. MEASURING PROCEDURE
4-1 Air Velocity Measurement
1)Install the " Probe Plug " into the " Probe Input Terminal "
( 3-14, Fi
g
. 1 ).
2)Power on the meter by pressin
g
the " Power OFF/ON
Button " ( 3-2, Fig. 1 ).
3)Select VELOCITY measuring mode by pressin
g
" VEL./FLOW Button " ( 3-7, Fig. 1 ) to get into velocity
measurin
g
mode.
4)Select the desired temperature units, by pressing the " /℃℉
Conversion Button " ( 3-4, Fig. 1 ).
5)Select the desired air velocity measurement units,
( mph, ft/min, knot, Km/h, m/s ) by pressin
g
the " Unit/
Button " ( 3-6, Fig. 1 ).
It is ready to measure air velocity when you finish abov
e
setting. Regarding other functions relative to Velocity
Mode please refer to following description.
6)
Data Hold Function:
During the measuring procedure, pressing the " Data
Hold Button " ( 3-3, Fi
g

and the LCD will indicate " HOLD " symbol on the left.
*
Press the "Data Hold Button" again to release th
e
data hold function.
7)
Data Record( Max., Min.
)
* Press the " MAX/MIN/. Button " ( 3-5, Fig. 1 ) once a
while to get into Data Record mode. A "REC" symbol
appears on the LCD display. At the same time meter
records value received by probe.

setting is the more accurate air flow value measured.
When you press the button you may see a " " symbol
appears and the fist di
g
it sparkling. Now you can continue
the area setting procedure.
6)Area settin
g
producre uses four buttons " ", "UNIT/ ",
" " and " MAX/MIN/. ". ( please refer to Fig. 1 page 4 )

*
" UNIT/ " button
Press one time to decrease one from the sparkled digit.
* " " button
Press one time to select next digit.
* "MAX/MIN/. " button
Setting the decimal point.
After you set the number you need, please press
"ENTER/RESET" button to finish the setting procedure.
For instance, if you want to set the sample area 120.3
square feet, please press " UNIT/ " button to make
sure " ft 2" appears on the display. Then press
" SAMPLE AREA " button to get into the measuring area
setting procedure. Press " " button one time to set 1
and press " " button to select the next digit. Press " "
button two times to set 2 then press " " button and press
" MAX/MIN/. " button to set the decimal point. Press " "
button three times to set 3 and press "ENTER/RESET" button
to finish the sample area settin
g
procedure.
7)Under air flow measurin
g
, we provide 3 kinds of flow mode
for you to apply by pressing the "FLOW MODE" button.
A
. 2/3V Max mode :
Selecting this mode you can get the 2/3 of the Max.
measured value. For instance Max. value is 300 CFM
but under 2/3V Max mode you can see 200 CFM only.

B.AVG mode :
Under this mode you can avera
g
e maximum 20 records
by pressing the " AVG.START " button manually. You
can see the avera
g
e number from the right-bottom o
f
LCD. The AVG formula listed as below:
1st Records +.........+ Nth Records
N
C.INSTANT mode :
LCD display shows measured number directly.
8)Under " 2/3V Max " and " AVG " mode, press
" ENTER/RESET " button to reset the previous settin
g
and restart measuring again.
9)
Data Hold Function :
During the measuring procedure, pressing the " Data
Hold Button " ( 3-3, Fi
g

5. RS232 PC SERIAL INTERFACE
The instrument features an RS232 output via 3.5 mm
Terminal ( 3-15, Fig. 1).
The connector output is a 16 digit data stream which
can be utilized by user's specific application.
An RS232 lead with the following connection will
be required to link the instrument with the PC
serial input.

6. BATTERY REPLACEMENT
1)
When the left corner of LCD display show " LBT ", 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 ( 3-16, Fig. 1 ) away from the
instrument and remove the battery.
3) Install a 9 V battery (PP3 type) and replace the cover.
