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)Important information of using the Telescope Probe * When the probe is not used, the " Sensor cover " should slide to the up position.
* When begin to use the probe, a. Slide the sensor cover to the down position, let the air velocity sensor to contact the air, refer Fig. 3. b. Extent the telescope probe to the convenient length ,refer Fig. 3 air velocity sensor ( do not touch by fingers or tools ) " Sensor cover " slide to the low position when make the measurement Probe Handle Fig. 3 * Do not use the fingers or any tools to touch the air velocity sensor, otherwise the meter may happen the permanent damage without warranty.
When sensor head face against the measurement air, then the upper display will show the air velocity value. The lower display will show the temperature value. Direction mark should face the measured wind. sensor head ( side view ) Fig. 4 Probe Handle 2) 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 ).
5) Hold the " Probe Handle " ( 3-21, fig. 1 ) by hand & let the " Sensor Head's mark " ( 3-20, Fig. 1 ) face against the measuring air flow source, then the Display ( 3-1, Fig. 1 ) will show air velocity directly. At the same time, the display will show the air temperature value. @ The Temp. unit adjustment, please refer Chapter 5-6. Measuring Consideration : The mark on the sensor head indicates the direction that " need to face against the air flow.
4)The display's bottom left side will show area size in Meter^2 ( or Ft^2 ) when make the air flow measurement. @ Meter^2 : Meter square, Ft^2 : Feet square. @ The adjusting procedures of area size, please refer Chapter 5-9. 5) Hold the " Telescope Probe " ( 3-21, fig. 1 ) by hand & let the " Sensing Head " ( 3-20, Fig. 1 ) face against to the measuring air flow source, then the Display ( 3-1, Fig. 1 ) will show air flow value.

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.
d)Manual Data Logger ( Sampling time set to 0 second ) Press the " Logger Button " ( 3-8, Fig. 1 ) once will save the data one time into the memory, at the same time the bottom right display will show the indicator " Recording.... " a while. Now the Data logger function is executed. The upper display will show " DATA " indicator along with " REC " marker. e) Memory full Under execute the data logger, if the bottom right display show the " Full ", it indicate the memory data already over 16,000 no.
5. ADVANCED ADJUSTMENT PROCEDURES When execute the following Advanced Adjustment Procedures should cancel the " Hold function " and the " Record function " first. The display will not show the " HOLD " and the " REC " marker. a. Press the " SET Button " ( 3-8, Fig. 1 ) at least two seconds until the lower display show XXXXX Memory Space * If push the " ESC Button " ( 3-3, Fig. 1 ) will escape the selecting function and return to the normal measuring display. b.
c. When make Advanced Adjustment Procedure will use the following key buttons : ESC Button ( 3-3, Fig. 1 ), Enter Button ( 3-4, Fig. 1 ) ▲ Up Button ( 3-5, Fig. 1 ), ▼ Down Button ( 3-6, Fig. 1 ) SET Button ( 3-8, Fig. 1 ), SEND Button ( 3-7, Fig. 1 ) 5-1 Check Memory Space To check the balance data numbers that exist into the memory ( allow memorize data no. ). XXXXX Memory Space @ XXXXX is the balance data numbers, for example XXXXX=15417.
5-4 Sample Time Setting * Use ▲ Up Button, ▼ Down Button and Enter ( →) Button to select the expect Sample Time ( HOUR-MIN.-SEC.). * After finish the Sample Time adjustment, Push the " Enter Button " , then press the " ESC Button " will quite and save the clock data into the memory. 5-5 Auto Power Off Default Setting * Use ▲ Up Button, ▼ Down Button to select " 1 " or " 0 ". 1 = Auto power On. 0 = Auto power Off.
5-7 Air Velocity Unit Default Setting * Use ▲ Up Button, ▼ Down Button to select the default Air Velocity unit as : m/S, Ft/min, Km/h, Knot, Mile/h, * After finish the Air Velocity unit adjustment, push the " Enter Button " , then press the " ESC Button " will quite and return to the normal measurement display. 5-8 Air Flow Unit Default Setting * Use ▲ Up Button, ▼ Down Button to select the default Air Flow unit as : CMM or CFM CMM : cube meter per minute. CFM : cube feet per minute.
5-10 Escape from the SETTING function Press the " ESC Button " once a while will quite and return to the normal measurement display. 6. HOW TO SEND THE DATA OUT FROM THE METER 1)If intend to send the data out from the meter, it should cancel the " Hold function " and the " Record function " first. The display will not show the " HOLD " and the " REC " marker. 2)Press the " SEND Button " ( 3-7, Fig. 1 ) at least 2 seconds until the bottom right display show " Transmit mode ", then release the button.
