Digiducer 333D01 USB Digital Accelerometer + Multi-Instrument Manual
Virtins Technology
supports Sampling Rate Conversion (SRC). That is, if you select a sampling rate that is not
natively supported by the hardware, the driver will do the sampling rate conversion
automatically without popping up an error message. Sampling rate conversion may introduce
additional noises and distortions. Thus for vibration measurement, it is recommended to use
the sampling rates that are originally supported by the hardware. Please check the hardware
specifications for details.
It is possible to use sound card ASIO driver for the USB accelerometer. The ASIO driver can
be downloaded from http://www.asio4all.com. ASIO driver only supports sampling rates
which are natively supported by the hardware.
1.4 Start Multi-Instrument Software
To start the Multi-Instrument software, with the USB accelerometer connected, on
Windows desktop, click the MI icon directly, or select [Start]>[All Programs]>[Multi-
Instrument]>[VIRTINS Multi-Instrument] (for Windows XP, Vista, 7 and similarly for other
Windows versions). The software will get activated automatically.
The USB accelerometer may not be the default ADC device used by the software. To
configure the USB accelerometer as the ADC device of the software, stop the oscilloscope
first by clicking the green button at the upper left corner of the screen, then go to
[Setting]>[ADC Device] and select “Sound Card MME” in the Device Model selection box,
and select “…333D01…” in the Device No. selection box. You can now use the USB
accelerometer to do vibration measurement.
If you want to use ASIO driver instead, select “333D01-ASIO4ALL” in the Device Model
selection box, and select “ASIO4ALL…” in the Device No. selection box. You need also to
select “333D01” in the ASIO4ALL panel. You can then use the USB accelerometer to do
vibration measurement.
