PROBLEM TO BE SOLVED: To effectively and automatically correct the detection voltage of the pressure sensor generating an offset to the value capable of surely determine the clogging for the≥3 pressure sensors for monitoring the clogging of the nozzle. SOLUTION: At the stopping of the spraying the asphalt emulsion, a compressed air is supplied into the≥3 nozzle main bodies 4. The adjusting method is composed of the following process: the first process for acquiring each detection voltage value by detecting the internal voltage of the each nozzle main body 4 by the≥3 pressure sensors 6 corresponding to each nozzle maine body 4; the second process for acquiring each deviation between the average pressure value and each detection pressure value, after calculating the average pressure value from each detected pressure value converted from each detected voltage value; the third process for acquiring the re-deviation between there-averaged pressure value and the detection pressure value generating a large deviation by calculating the re-averaged pressure value from each detection pressure value except the detection pressure value generating the large deviation; and the fourth process for correcting the detection voltage value of the pressure sensor 6 corresponding to the detection voltage value generating the large deviation by making the difference between the previous offset value and the voltage value obtained by voltage converting the re-deviation, the new offset value.
