The FW Fullwaver systems were specifically developed for precise full waveform time domain induced polarisation, Resistivity and self-potential measurements. Each system is fully independent; incorporating its own power source, GPS module and digital memory for up to 3 months continuous recording.
The V Fullwaver is a dual channel Induced Polarisation, Resistivity and SP receiver. Continually recording at 10ms sample rate provides a full waveform record. It can be synchronized on the GPS PPS signal, allowing an easy process of the signal. Data on the memory can be downloaded directly on a simple USB stick from all the Fullwavers.
The I Fullwaver sits in series between the injection electrode and transmitter (e.g. TIPIX, VIP) recording the AB injection current to within 3mA. Sampling at up to 100Hz, the GPS PPS is used to synchronise an internal clock in order to accurately time stamps each record within an absolute accuracy of 250us. The I Fullwaver can be used alongside the V Fullwaver or Elrec Induced polarisation receivers.
The timeseries recorded by the I&V Fullwavers can be post-processed on the dedicated software Fullwaveviewer that allow to adapt the processing according to the signal/noise ratio, to focus on stable and accurate parts of the signal, to remove SP spikes and to resynchronize the data if necessary. This software allows also a rapid automatic process of the data and thus export resistivity and chargeability data to compute a first 3D model in few minutes.
