What is the meaning of the settings unit "xx% FS" on D7F-C03 Vibration Sensor Level Meter?
The display/settings unit of the D7F-C03 Level Meter is % FS.
FS is an acronym for full scale. It indicates the full size of the measurement range.
Therefore % FS indicates a fraction of the full scale, in the form ××%.
Set the operating mode to ACC (acceleration) and the GAIN switch to the ×1 range.
Referring to the specifications in the D7F catalog, the corresponding full scale is 98 m/s2
Under these conditions, looking at the indicators,
The threshold setting 55% to 65% FS, in terms of acceleration, becomes 98 m/s2 × 0.55 = 53.9 m/s2. Following this calculation, the range is 53.9 to 63.7 m/s2.
