The Anemometer and wind vane are shipped into their original packing to prevent damages due to transportation. It is necessary to fix the wind wane properly to be able to orient the device so it will indicate North East West South properly.

Adjustment can be done in 2 ways:
  • 1) placing a call to the unit and listening to the voice reading the degrees
  • 2) using a voltmeter and reading the values in volt corresponding to the degrees.

  • 1) To ajust the wind direction placing a call do as follows:
  • Switch on the unit with a SIM and wait for it to register to the network
  • Send the command #WDC ( after the #PWD command, as usual). The unit, for 10 minutes, or until switched off, will now read the direction in degrees whenever you place a phone call.
  • Place a phone call and listen to the degrees. Turn the knob until you hear 180 (south). Mount and fix the wind vane so it points south.
  • Switch off the unit and it is ready to go.

  • 2) To adjust the wind direction measuring the voltage you need to use a multimeter (or a voltmeter) to measure a voltage that goes from 0 to 5 volts. You don't need to put a SIM to do this calibration. You simply need to switch on the unit. Follow the instructions and the picture below...

  • 1- If the unit is not already switched on, connect the battery cable and push the power button to start up the unit.
  • 2- measure the voltage between the black and white wires, in the 2 pins connector shown in the picture,
  • 3- Turn the knob of the potentiometer until you read 2.5 Volts, that is South (180 degrees)
  • 4- Fix the plastic vane to the knob so it points the pole, as shown in the picture below
  • 5- Orient the pole towards North, when you will install the station
