The vector sum of the vibration velocity in the three directions X/Y/Z and the highest amplitude together
with its main frequency are displayed every second. On the right side of the screen, a graph displays this
value in the frequency range. The diagram is scaled to the limit curve. Higher magnitudes will be cut off.
If the limit value is exceeded, “ALARM” is displayed below the main frequency and the following will
happen:
- The red light will flash.
- The measurement values will be saved if the event recording has been activated.
- The relay output will switch if it has been activated.
- An SMS will be sent if this option has been set up on the PCE-VM 40B.
Note: The alarm and recording functions will be activated after a delay of 30 seconds after leaving the
menu.
5.5 Non-standardized measurements
If a standardized measurement is not desired, the vibration quantity (acceleration or velocity), the
frequency range and the limit values can be entered manually. For this option, select the measuring mode
“non-standardized”.
You can select the vibration quantity and frequency range in the next step.
After this, the points which define the limit value curve can be entered. The lowest and highest
frequencies are fixed. The amplitudes and the two middle frequencies can be freely selected within the
range limits.
As with the other measuring modes, your chosen measuring settings can be viewed during the
measurement by pressing F1.
