Set area unit
While enter the setting model, Press UNIT ▲ or UNIT ▼ to choose area unit interface.
- Press ENTER key, the screen display word “AREA” and area unit.
- Press UNIT ▲ or UNIT ▼ to choose the area Unit.
- Press ENTER key to store the choosing unit.
Settings
Setting method:
When the power is ON, long press the SETUP. The screen display the Unit as shown in the figure.
Press the up arrow key to choose ft2 or m2. After choosing, press the key “SETUP” and the screen display the AREA and area value as shown in the figure.
Press the key Up/Down to adjust the value from 0.001 ~ 9999. “Flow/temperature” can choose decimal point. After choosing, press “SETUP” key and the screen display “SPL” to set power off. Press UP key to choose ON/OFF. After choosing all parameters long press “SETUP” key to store the setting.
Operations:
- Insert the probe to the probe socket. (Note: battery and power supply can’t be used in the meantime)
- Press power off button to power the sensor.
- Choose the wind speed unit and temperature unit.
- Zeroing operation:
a.Slide the sensor cover to the sensor position to make the heat sensor
b.After the value are stable, press HOLD/ZERO button 2 seconds, when the screen display four “0”, the wind speed value is zero.
5.Insert the sensor cover the opposite position, adjust the right length of the sensor handle to let the heat sensor exposed in the air.
6.Direction of the sensor. The sign on the top of the “sensor” should face to the measuring wind direction. Then the screen display the wind speed value, the lower display the temperature value.
