FAQ#083 – How does the TRIGGER function of OMNIAlog digital input work?
The TRIGGER function of the two digital inputs available on OMNIAlog datalogger is typically used with seismic station. In case of an event (earthquake), the seismic station is usually able to supply a certain tension on its output (typically 5Vdc). If this output is connected to the digital input of OMNIAlog, and OMNIAlog is conveniently […]
FAQ#082 – Is there any precaution to adopt for the number of measurements saved on the OMNIAlog / miniOMNIAlog memory?
OMNIAlog is equipped with a microSD 2GB memory. This memory allows to save a very high number of readings. For this reason, it is necessary to bear in mind what follows: Therefore SISGEO strongly suggests to periodically download data and, later, to delete them from OMNIAlog memory. This way it is guaranteed an efficient data […]
FAQ#081 – Which is the maximum cable length for DEX and DEX-S probes?
The maximum instrument cable length from DEX probe to datalogger is 200 m. If the automatic data acquisition system includes distributed external multiplexer box, the maximum cable length is 200m from DEX probe to multiplexer box plus 200m from multiplexer box to OMNIAlog (in total 400m).
FAQ#080 – What dimensions has the .CSV file in columns that contains the measures acquired with OMNIAlog and miniOMNIAlog?
The dimensions of the measures file “in columns” downloaded with OMNIAlog and miniOMNIAlog vary according to the number of sensors acquired and the stored cycles of acquisition. The higher is the number of sensors acquired and the number of cycles of acquisition stored, bigger is the dimension of the file. It could be used the […]
