6.11 Full Waveform Data
Internally the instrument records data with 1 millisecond resolution. This data is
filtered and averaged in order to provide the measured voltages, resistances, and
chargeability’s that are displayed and saved. By default the full waveform data with
millisecond resolution is not saved, but it is possible to do so in order to make it
possible to analyse the received signals in detail afterwards.
Saving full waveform data opens possibilities to view and analyse the received signals
in detail afterwards. This makes it possible to identify and understand the occurrence
of for example excessive power line network noise, telluric noise, signal disturbances
caused by cable coupling, etc. This in turn may be useful as input for how to optimise
the data acquisition process, especially for IP measurements which are more sensitive
to noise than resistivity measurements.
Chapter 5.2.2 Data Acquisition Settings describes how this feature is turned on or off.
Be aware that turning the feature on means saving large amounts of data that can fill
the disk, and will take significant time to transfer from the instrument to a PC. It is not
recommended to attempt to copy a Project containing full waveform data to a USB
disk, as it will take a long time.
6.12 Measurement Errors
A number of different errors or warnings can occur while measuring. This chapter
explains the handling of these errors and warnings.
A Measuring Error dialog will be shown when a measurement error occurs. Figure 72
shows an example:
Figure 72. A Measuring Error dialog example
The layout of the dialog is always the same. The large text box in the upper area
contains specific and general event information. In the lower area there are four
commands lined up.
