In order to prevent the wind speed measurement and alarm function from staying in the setting state for a long time after the operation is interrupted, if there is no key operation for 30 seconds in the setting state, the instrument will automatically return to the measurement state and the original unfinished setting value will be abandoned. After setting the alarm value, press the function key again and the instrument will return to the wind speed measurement state. However, the alarm value should be greater than the pre-alarm value. The setting method of the alarm value is the same as the setting of the pre-alarm value, and will not be repeated here. The instrument enters the alarm value setting state. At the same time, the pre-alarm value set just now will be sent to the instrument to replace the original setting value and stored in the EEPROM of the program monitor so that Pre-alarm setting values are saved during power failure. After setting, press the function key once and the instrument will enter the alarm value display and setting state. Up to 60m / s, and each time you press "-1 / Alarm Reset", the pre-alarm value will decrease by 1 m / s, until 0 m / s. Each time you press "+ 1 / pre-alarm reset", the pre-alarm set value increases by 1 m / s. If you need to modify the pre-alarm setting, you can apply "+ 1 / pre-alarm reset" and "-1 / alarm reset". The display and setting resolution of the pre-alarm value is 1m / s. If there is no need to change it, press the function key again to enter the next working state. The instrument first displays the original pre-alarm setting value of the instrument. When the function key is pressed once in the wind speed measurement state, the instrument enters the display and setting state of the pre-alarm value.
