This must be specified for each relay address that is not in the internal switch. It is
automatically taken care of for switch addresses above 64 if a spread description in
ADR-format is converted using the Terrameter LS Utility Software (version 0.1.3 or
higher).
12.3 Protocol Files in XML-format
The protocol files describe which electrode arrays are used and the measuring
sequence, and can be designed to do measurements using arbitrary arrays. A protocol
file always refers to at least one spread description file, which simplifies the protocol
files immensely since each electrode is simply referred to by its number as defined
within the <Name> tag in the spread description file.
Explanations to the tags:
•
<SpreadFile> specifies the associated spread description file. There may be more
than one alternative spread file, in which case this statement is repeated.
• <Sequence> marks start and end of the measuring sequence.
•
<Measure> defines a measurement or set of measurements using one current
electrode pair.
• <Tx> specifies the current electrodes used for a measurement.
• <Rx> specifies the potential electrodes used for a measurement; there can be an
unlimited number of potential electrode pairs for a current electrode pair.
• <Focus> are the pseudo section focus points for the current and potential electrode
combination calculated for an electrode spacing equal to one, will be scaled
according to the actual electrode spacing.
Examples
A <Measure> section in the XML measuring sequence file can look like this example:
<Measure>
<Tx> 1 64 </Tx>
<Rx>
22 43
<Focus>
<X> 32.5 </X>
<Z> 10.92 </Z>
</Focus>
</Rx>
</Measure>
This example shows a normal Wenner array, for which it is not possible to utilise the
multi-channel measuring capability.
Multiple gradient array, on the other hand, is efficient for multi-channel measuring,
and a <Measure> section may look like the example below:
<Measure>
<Tx> 1 61 </Tx>
<Rx>
