From version xxx.021: The text entered when saving without VMID point will be
displayed instead of the VMID point serial number (compare section 6.4).
The RMS and peak value are displayed underneath the date, time, display mode and
filter type. (25).
Press ▼▲ to scroll to the next measurand. The currently displayed measurands can
be deleted by pressing F1. Press F3 to exit the menu.
The VM24 memory can hold 16000 measurement values.
6.7. Deleting Saved Measurement Data
In the menu option “Measurement data” / “Erase meas. data Memory” you can
delete the entire measurement data. After pressing OK a warning message will ap-
pear showing the total number of records.
7. Measurement Evaluation with Standard Values
To be able to derive statements from the measured vibration velocity values about
the condition of a machine, experience is necessary. If experienced personnel are
not available, in many cases one can refer to the ISO 10816 recommendations. In
these sections of the standard, the vibration severity zone limits for various machine
types are defined, which can provide an initial evaluation of a machines mainte-
nance condition. The four zone boundary limits characterize the machine in cate-
gories according to vibration severity:
