Measuring condition
Part shall be measured under a condition (Temperature: 5½35℃, Humidity: 45%½85%R.H., Atmospheric
pressure: 860
½1060hPa)
unless the standard condition (Temperature: 25±
3℃, Humidity: 60±
10%R.H.
Atmospheric pressure: 860
½1060hPa)
is regulated to measure.
C: Acoustic Characteristics:
The oscillation frequency, current consumption and sound pressure are measured by the
measuring instruments shown below
In the measuring test, buzzer is placed as follows:
