The VM-53/VM-53A consists of the main unit and the 3-axis
accelerometer PV-83C. It conforms to the requirements specified by
the Weight and Measure Act and the Japanese Industry Standard for
vibration level meters (JIS C 1510: 1995). The unit is designed mainly
for measuring ground vibrations in order to evaluate vibration pollution.
It can measure vibration levels and display values weighted according
to human vibration sensitivity characteristics. The VM-53/VM-53A can
also be used to measure minute vibrations in structural objects.
Sophisticated auto store and timer functions enable unattended
long-term measurement. Data can be stored in the internal memory,
and the VM-53A can also use memory cards (CompactFlashTM cards)
to hold large amounts of measurement data.
The main unit features two backlit LCD panels. The large main display
shows the instantaneous value, while the sub display can show a
level-time waveform (3-axis or single-axis), bar graph (3-axis), list of
numeric values, or other valuable information. This lets the user
evaluate vibration phenomena much more accurately than with a
conventional device.
Separate X, Y, Z signal outputs are provided. An I/O jack for
connection to a printer or computer and a comparator output are also
available. This makes the VM-53/VM-53A suitable for a wide range of
measurement system applications.
The unit can be powered from IEC R14 (size C) batteries or from an
AC adapter (option). A backup function to guard against data loss in
case of a power failure is also implemented (when batteries and AC
adapter are used together).
■Twin backlit LCDs. Large main display shows instantaneous value
while sub display shows level-time, bar graph, list,
or other information.
■Continuous recording of 3-axis instantaneous value data on memory
card possible (VM-53A).
(Approx.400 hours using supplied 64 MB card, 3-axis data, 1-second intervals)
■Store processed values for maximum value, instantaneous level, and
power average in internal memory or on memory card.

* Remote measurement is possible with the four models VM-53/VM-53A
and VM-52/VM-52A. (For remote measurement, the vibration level meter is
connected to a PC via a serial link. Vibration level meter setup and
processing measurement can then be controlled from the PC.
