To establish a connection to
3&(
VS10, press
Search VS1x
. The program searches COM-Ports 1 to 50 for the in-
strument. As soon as it has been found the status report
VS1x connected
appears and the instrument settings
are read.
In the row next to the COM port number you will find the non-editable data, model, version, serial number
and date of calibration. You can enter the device name yourself.
When entering the gain, this refers to the analogue pre-amplification before the analogue-to-digital converter
stage. The gain levels 1, 10 and 100-fold are available for selection as well as automatic gain switching. In
many cases automatic gain setting is most appropriate. It can, however, occasionally be disadvantageous if
single shock pulses are measured. If previously only low amplitudes had been recorded, it may occur that
short single impulses fail to trigger the alarm signal immediately, due to the switching of the gain. In such
cases a fixed gain should be set according to the maximum expected amplitude (
fix
).
Under
Filter / Integrator
there is a row of high and low pass filter combinations to choose from. Depending
on the area of application, you can monitor either acceleration without integration (
accel
.) or the single inte-
grated signal of velocity (
veloc
.). For vibrations below 1 kHz, for which the resulting energy is of relevance,
it is recommendable to monitor velocity, whereas for measurements involving higher frequencies and im -
pacts, acceleration is usually preferred.
Under
Warning/Alarm
you can find the limit value settings. Here your can select whether
RMS
values or
Peak
values are to be monitored. Monitoring peak values can be advantageous for recording single events,
while RMS is relevant for trend monitoring, for example, in the field of machine condition monitoring. The
Alarm limit
is entered in the unit of measurement (m/s² or mm/s). The instrument can give a warning signal
before it reaches the alarm limit. The warning threshold is entered as a percentage of the alarm limit.
