Monitoring measured vibration values, maximum while measuring
1. While measuring, the maximum / v / and / a / and the frequency are directly visible in x, y, z-
direction per time interval. The displacement option / u / is only available with the VIBRA
+
.The
system also displays date and time and visibly counts down the remaining interval time. Use
the /-keys to scroll and view the measured values.
2. Press to view the maximum value(s). These are the highest measured values since
measuring has been started or since resetting the maximum value(s). These values include
the frequency in the x-, y- or z-direction with date and time. The display of the maximal
displacements is only available in the VIBRA
+
.By pressing 2 CLR , values shown are reset to
zero (without loss of data).
3. Press again to view the system information and the measuring values registered in
accordance with the governing code:
• the v
eff,max
–values in accordance with SBR 2002 are shown (VIBRA-sbr only).
• the KB-values in accordance with DIN 4150 or the v
eff,max
-values in accordance
with the SBR (VIBRA
+
only).
A data save level of 0.1 has been set for both the KB and the v
eff,max
–measurement, as
specified in the respective governing codes. Measuring values below this threshold are not
saved and displayed as 0 in the PC software.
