4. Tuning and repair
4.1 The electrical circuit inside the wind display has already been adjusted, so
there in no need for further tuning. In the event of sufficient depreciation and
/or rough transport conditions, the display can be inaccurate, or the preset
limit can be biased. In this case, a specialist can open the box and adjust the
corresponding potentiometer;
Each potentiometer has the following purposes:
W1--13m/s limit alarm setup；
W2--20m/s limit alarm setup；
W3—LED bar full capacity adjustment；
W4—wide-angled needle display full capacity adjustment；
W5—test signal magnitude adjustment；
