Additional Information:

Basic Settings:

Preset the below parameters before taking measurement:

  1. Unit of temperature: °C, °F
  2. Unit of humidity: %RH, td (dew point), WB (wet bulb)
  3. Unit of velocity: m/s, km/h, fpm, mph, kts, Bft
  4. Flow unit: ft, m, nis, CFM

Switch the device off: Manually or automatically (automatically goes off if none of the key is pressed for 10 minutes)
Device on > Pressing the long time “Power” key it will enter the setting mode. Press “Down Arrow” button several times until the desired unit flashes. Press “Mode” button to confirm.
Switch into measuring mode after the setting is done, the setting is invalid if the device is turned off under the setting mode.

Operation Instructions:

To ensure correct measurements, please follow the notes below

  1. Position the instrument so that flow impacts at the rear
  2. Keep temperature and humidity sources which may falsify the measurement (e.g. hands) away from the sensor.
  3. Switch on: Press “power” button

Switch the back light on: Device on > press the light glow button. The display light goes off automatically if the key is not pressed for 10 seconds

To select the parameters:
Device On> press upper arrow button to switch between temperature and wind chill measurement.

Changing the display view:
Long press of mode button, the following readings displayed one by one:
Hold>Max value> Min value>Avg value.
Those data will not be recorded after the device is switched off.

Battery Replacement: Change new batteries as soon as possible when the low voltage indicator displayed. Use only batteries of 1.5V AAA. Observe the polarity.
Hi and Low indicate the measurement is out of range.
