Minimate Pro Operator Manual
(5) Record Mode - Vibration Dose Value (VDV) [Optional]
The optional Vibration Dose Value ( VDV ) Record Mode is available on the unit with
the purchase of the Instantel® Blastware Advanced Module software. To order your
copy of the Blastware Advanced Module , please contact your Instantel Dealer
Representative . If you have a licensed copy of the Blastware Advanced Module ,
follow the instructions in the Blastware Operator Manual for Reloading the
Operating System of the Minimate Pro , which will also load the VDV recording mode
into the unit if it is not already there.
The VDV monitoring option is used to measure and determine whole-body vibration
based on a Frequency Weighting file that is downloaded from Blastware . The VDV
Record Mode will not be allowed unless a Frequency Weighting file is downloaded to
the unit. Your geographic location and the type of vibration that you are monitoring will
determine which
Frequency Weighting file that you choose to use during the monitoring
session – the frequency range of the data collected is from 1 to 80 Hz, therefore the
Instantel 1-80 Hz DIN Geophone (Part No. 720A2003) is required for this type of
recording, as the sample rate is reduced to 512 s/s. Multiple VDV frequency weight files
may be downloaded to the monitor using the Blastware Advanced Module software.
Refer to the Blastware Operator Manual for more information on how to download
weight files to the unit.
While monitoring, the unit differentiates the velocity data into acceleration, applies the
frequency weighting and then calculates the
VDV and Root Mean Square ( RMS )
values. The unit displays the VDV and RMS values every ten seconds while recording,
and stores the final calculations as part of the file and Event Report.
There are two primary standards for determining and evaluating whole-body vibration, as
follows:
BS-6841 Measurement and evaluation of human exposure to whole-
body mechanical vibration and repeated shock.
ISO-2631 Evaluation of human exposure to whole body vibration.
These
Series IV units are capable of continuously monitoring full waveform data for 24
hours; the daytime VDV monitoring is performed on the vertical channel (7:00 AM to
11:00 PM) while the nighttime VDV monitoring is performed on two horizontal channels
(11:00 PM to 7:00 AM) – the same or different Frequency Weight file can be use for
each of these monitoring periods.
NOTE: The VDV Record Mode consumes more battery power than other record modes.
We recommend connecting the monitor to the supplied AC adapter or an external 12
VDC power supply.
