OPERATING GUIDANCE

Power On/Off
Press the"POWER" key to turn on or off the anemometer power.
Reading hold
In the measurement process, if the reading should be kept, press "HOLD" key to lock the reading, and display the HOLD symbol; press it again to unlock.
Note: In the reading hold state, "FUN", "MAX/MIN" and "UNIT" keys are invalid.
Backlight
In the measurement process, if the ambient light is too dark to read, you can press"" key to open the backlight. Backlight timer is set to 15 seconds. During this period, you can press"-:+:-" key again to turn off backlight at any time.
Note
1. The luminous body of backlight is LED with large operating current. Frequently using backlight will shorten battery life. Do not use backlight when unnecessary.
2. When the battery voltage::; 7V, the" " (low battery) symbol will show on the display. However, in the case of using the backlight, if the battery voltage 7V, the battery voltage drops because of its larger operating current, "" symbol may show (when "" symbol is showing, the accuracy of the measurement can't be guaranteed). At this moment, you needn't replace battery until the"" symbol display again under normal use condition without using backlight.
Wind speed measurement
Place the detector (fan) into the test environment, "VEL" symbol will display on the screen, measurement is done with the fan surface perpendicularly to the wind direction.
Note
- If the detector (fan) is not aiming at the wind direction, which will bring the measurement error.
- For steady wind, the detector (fan) will get maximum reading when it is aiming at the wind direction.
Wind speed measurement
When using the meter to measure air volume, you can press "UNIT" key to select the measurement unit you required (m/s, km/h, mill/h, ft/m, ft/s, knots).
Area setting
- To measure air volume, you should first determine the area of air flue to be, area input steps are shown as following:
- Press "FUN" key to make "AREA" display on the screen.
- Use the "MAX/MIN" and "UNIT" keys to adjust value and unit, after adjusting area unit (m2 , ft2 ), then press "MAX/MIN" key. There should be an audible buzz, indicating that area input is completed and settings are saved.
- To change the area setting, please repeat the step
Air volume measurement
Place the detector (fan) into the test environment. Use the "FUN" key to set the meter to the Air volume measurement mode; the "FLOW" symbol should display on the screen.
Measurement is done with the fan surface perpendicular to the wind direction.
Note
1. If the detector (fan) is not aligned in the wind direction, the measurement can be skewed.
2. For steady wind, the detector (fan) will get maximum reading when it is aiming at the wind direction.
Air volume unit selection
When using the meter to measure air volume, you can press the "UNIT" key to select the measurement unit your required (CMS, CMM, CFM).
Temperature unit selection
Long press the "UNIT" key for 3 seconds to switch temperature unit (° C, °F).
Temperature mode selection
Long press the "HOLD/MODE" key for 3 seconds to switch temperature mode (ambient temperature, dew point temperature and wet bulb temperature).
USB real time data uploading
Long press the " USB" key for 3 seconds to enable or disable USB real time data uploading function.
Detailed steps are shown as follows:
1. Use CD to install the PC software and the USB drivers.
2. Power on the meter and connect it to a computer with USB cable.
3. Launch the PC software.
4. Long press the"/ USB" key for 3 seconds to enable the USB function of the meter.
5. The PC software displays data and diagrams.
6. Save or print data.
Using tripod connection receptacle
1. When necessary, the meter can be fixed on a tripod.
2. When necessary, the meter can be used by hang.
Replacing battery
1. If the “”sign appears, this indicates that the battery should be replaced.
2. Power off the meter and remove the battery cover.
3. Replace the old battery.
4. Install the battery cover properly.
