4. GENERAL MEASURING
PROCEDURE
The meter default value are following :
* The air velocity unit is m/S.
* The temperature unit is .℃
* The air flow unit is CMM.
* The air flow area is meter^2 ( meter square ).
* The sampling time of data logger function is
2 seconds.
4-1 Air velocity /Air Temp. measurement
1)Install the " Probe Plug " ( 3-19, Fig. 1 ) into the
" Probe Input Socket " ( 3-17, Fig. 1 ).
Attention :
After install the " Probe Plug ", should slide
Probe Lock Switch " ( 3-18, Fig. 1 ) to the On
position ( right position ).
2)Power on the meter by pressing the " Power Button "
( 3-2, Fig. 1 ).
3)Select measuring function by pressing " Function
Button " ( 3-6, Fig. 1 ) until the display show the
air velocity unit.
@ Air velocity measurement, the display unit
will show m/S ( or Ft/min, Km/h, Knots, Mile/h ).
@ The Air velocity unit adjustment, please refer
