Description of the systems interface in standalone mode
-
PS: Spontaneous Potential, automatically measured by the system and used to
purify the final measurement of the resistance, in Volts.
-
IP: decay time measured in milliseconds.
-
K: geometric constant dependent on the relative positions of the electrodes used
for the measurement and used for the calculation of Rho. It is calculated by the
application in the cases in which measurement campaigns supported by tables are
carried out, it is not possible to calculate it in the case of a single measurement in
which the positions of the electrodes are not known. In the second case the value
of K is not shown on the display.
-
R = V / I: Resistance measured as a ratio between V (M-N) and I (A-B), in Ohms.
Measurement of spontaneous potential
Spontaneous Potential measurement is performed as a single measure, the result of which
is presented to the operator on the video as shown in Figure 19.
Below are listed the values done after a measure of only spontaneous potential.
- PS: Spontaneous Potential, automatically measured by the system, in Volts.
If the measurement is made as an effective single measurement and without the aid of a
measurement session, the operator must copy the electrical parameters obtained with the
measurement, if deemed necessary, as the single measurement mode does not allow the
measurement memory storage of the result tool.
In case the measurement execution is controlled through the execution of a measurement
session (see paragraph Execution, editing and repetition of a measure in session ) after
visualizing the measurement result, the operator must accept or reject the measurement
result on the instrument. In the first case the measured electrical parameters will be
