Velocity is the most commonly used parameter and is used to measure vibration in
accordance with ISO 2372, BS 4675, VDI 2056 and ISO 10816. Velocity is measured in mm / s.
Vibration displacement measurement mode
Due to its good low frequency response, this parameter is usually used in low speed
applications. The unit for this parameter is mm.
2.3.3 Measurements
Switch on the device and set the operating mode by pressing the "
" key several
times until the desired mode is displayed. The modes are set in the following order:
"acceleration" (m / s2) - "speed" (mm / s) - "displacement" (mm) - "ratio of peak and
root-mean-square vibration values".
Place the Vibration Meter Pen on the object of measurement and press it perpendicularly
to the surface of the product with a force of 2 to 5 kg, ensuring reliable contact of the sensor
with the object, press and hold the "
" key - the device will start measuring vibration.
The measurement result is displayed on the LCD.
During of measuring vibration, the device makes cyclic measurements at intervals of one
second. The vibration value is shown on the display until the end of the next measurement.
For more accurate measurement results, it is recommended to measure two or three times. If
the readings are unstable, check that the force is applied and the instrument is positioned
correctly.
When machines (mechanisms) are operating under the same conditions, you can use a
Vibration Meter Pen to carry out comparative measurements. By analyzing the data obtained,
it is possible to detect possible malfunctions of individual machines at an early stage. To
achieve high accuracy with the instrument, you must make sure that these measurements are
always taken at the same points.
Note - The device uses the power saving mode. If the device is left on, it will turn off automatically
after 20 seconds.
