g
the " Power OFF/ON
Button " ( 3-2, Fi
g
. 1 ).
3)Select VELOCITY measurin
g
mode by pressin
g
" VEL./FLOW Button " ( 3-7, Fi
g
. 1 ) to
g
et into velocity
measurin
g
mode.
4)Select the desired temperature units, by pressin
g
the " /℃℉
Conversion Button " ( 3-4, Fi
g
. 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, Fi
g
. 1 ).
It is ready to measure air velocity when you finish abov
e
settin
g
. Re
g
ardin
g
other functions relative to Velocity
Mode please refer to followin
g
description.
6) Data Hold Function:
Durin
g
the measurin
g
procedure, pressin

g
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 pressin
g
the "FLOW MODE" button.
A
. 2/3V Max mode :
Selectin
g
this mode you can
g
et 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.
A
VG mode :
Under this mode you can avera
g
e maximum 20 records
by pressin
g
the " AVG.START " button manually. You
