Measured quantities
Measured quantities in the vibration meter mode: RMS, PEAK, P–P and MAX.
Definitions for mentioned parameters are given in Appendix D.
Mounting for vibration tests
The accelerometer can be connected with the VLM using proper cable provided by the manufacturer.
The accelerometer can be mounted on the shaker in various ways:
• using threaded stud onto a flat, smooth surface,
• using thin layer of beeswax for sticking the accelerometer into the plate,
• using mica washer and isolates stud, where the body of accelerometer should be electrically isolated from
the measuring object,
• using permanent magnet.
Linear operating ranges
Linear operating ranges for the acceleration (with SV 80 accelerometer with a sensitivity equal to 10 mV/ms
-2
@ 79.58 Hz).
Two ranges with the nominal values:
Low 100 ms
-2
(160 dB related to 10
-6
ms

)
High 354 ms
-2
(171 dB related to 10
