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)Important information of using the Telescope Probe
*
When the probe is not used, the " Sensor cover "
should slide to the up position.
When the probe is not used, the
" Sensor cover " should slide to the
up position.
