5.6 Overload indication
If the vibration magnitude exceeds the limits shown in the Technical Data section, the PCE-VM 40 will
indicate “OVERLOAD” instead of the measuring value for the respective direction.
In addition, the warning and alarm LEDs flash simultaneously.
Due to integration, the overload limit for the vibration velocity is frequency-dependent.
5.7 Saving measured values
Introduction
The PCE-VM 40 has memory space for 100,000 measurements. The saved data can be viewed via the
instrument menu or transferred to the PC via the USB interface.
A measurement record includes:
- Date and time
- Measurement values X/Y/Z or the vector sum
- Main frequency
- Trigger event
The instrument saves the data if any of the following events (triggers) occur:
- a warning or alarm event occurred
- a predefined time interval expired
Alarm events occur if the limits described in Section 3 are exceeded.
Warning events occur if the warning threshold is exceeded
Saved measurements are sorted in to data files in the PCE-VM 40. A file contains related measurements
with the same settings.
