MEASURING PROCEDURE

Air velocity/Temperature measurement

1. Install the ” Probe Plug ” ( 3-13, Fig. 1 ) into the ” Input Socket ” ( 3-8, Fig. 1 ).
2. Power ON the meter by pressing the ” Power Button ” ( 3-2, fig. 1 ).
3. Select the desired air velocity unit ( m/s, km/h, mph, knots, ft/min ) by pushing the ” unit Button ” ( 3-5, fig. 1 ).
4. Select the desired temperature units by pushing the ” Button ” ( 3-6, fig. 1 ).
5. Use the hand ( or tripod installation ) to hold the ” Probe Handle ” ( 3-12, Fig. 1 ), face the ” Vane Probe Head ” ( 3-11, Fig. 1 ) to the measured wind. In the same time the air velocity and the temp. value will show on the LCD display.

Measuring Consideration:
The ” ” mark on the sensor head indicates the mark need to face against the direction of airflow.

4-2 Data Hold, Date Record

1. Data Hold
   • During the measurement, pushing the ” Data Hold Button ” ( 3-3, Fig. 1 ) will hold the measured value & the LCD will indicate ” HOLD ” symbol.
   • Push the ” Data Hold Button ” again to release the data hold function.
2. Data Record ( Max., Min. reading )
3. The data record function records the maximum and minimum readings. Press the ” REC. Button ” ( 3-4, Fig. 1 ) to start the Data Record function and there will be a ” REC ” symbol on the display.
   • With the ” REC ” symbol on the display : * Press the ” REC Button ” ( 3-4, Fig. 1 ) once, the ” REC Max ” symbol along with the maximum value will appear on the display.
   • Note: If intend to delete the maximum value, just press ” Hold Button ” ( 3-3, Fig. 1 ) for a while, and then the display will show the ” REC ” symbol only & execute the memory function continuously.
   • Press the ” REC. Button ” ( 3-4, Fig. 1 ) again, the ” REC Min ” symbol along with the minimum value will appear on the display.

Meter: (3.5 mm jack plug)
PC: (9W ‘D” Connector)The 16 digits data stream will be displayed in the following format :
D15 D14 D13 D12 D11 D10 D9 D8 D7 D6 D5 D4 D3 D2 D1 D0

Each digit indicates the following status :

For example :

If the display reading is 1234, then D8 to D1 is : 00001234

D9| Decimal Point(DP), position from right to the left

0 = No DP, 1= 1 DP, 2 = 2 DP, 3 = 3 DP

D10| Polarity

0 = Positive      1 = Negative

D11 & D12| Annunciator for Display
| | m/s = 08
Km/h = 10| ft/min = 11| mile/h = 12
knot = 09|  |
D13| When send the upper display data = 1
When send the lower display data = 2
D14| 4
D15| Start Word

RS232 FORMAT: 9600, N, 8, 1

BATTERY REPLACEMENT

1. When the left corner of LCD display show ” it is necessary to replace the battery. However, in-spec. measurement may still be made for several hours after low battery indicator appears.
2. Slide the ” Battery Cover ” ( 3-9, Fig. 1 ) away from the instrument and remove the battery.
3. Replace with 9V battery ( Alkaline or Heavy duty type ) and reinstate the cover.
4. Make sure the battery cover is secured after changing the battery.
