BISOPE series 66 How to set the appropriate frequency for measurement Setting the maximum frequency

uency after identifying the following. Above all, the most basic principle is that the frequency group to be confirmed should be measured and arranged so that it is visible in the center of the screen.
1. Understand the specifications of the machine
- Rotational speed of the drive component (number of poles of the motor, electric frequency, number of blades of the turbine, sleeve or rolling bearing, other rotating elements)
- Sleeve bearings must be able to measure low frequencies well.
- Rotation event information of the driven component (number of blades, number of vanes, sleeve or rolling bearing, number of gear teeth, other rotating elements)
- Measurement is good up to 3 times the blade passing frequency (BPF).
- Measurement is good up to 3 times the gear meshing frequency (GMF).
er the number of lines (resolution) and the shorter the frequency setting, the longer the measurement time. (In the case of 100Hz, 1000 lines, the measurement time per block size is 10 seconds.)
-Set the speed (mm/s rms) and observe and evaluate the frequency of all bands. Then change the unit.
