7.1.3 Recording spatially assigned measurement sequences
(MATRIX)
Assigning measurement values to the spatial location where the measured
value was obtained is very time-consuming when a series of measurements
is evaluated. If the measured values are stored as a matrix, subsequent
processing can be simplified with suitable computer programs.
Tip: Before recording a matrix for the first time, it is a good idea to look at
the procedure as outlined in Annex B as this will give you a better
understanding of the technical background.
Note:
• Measurement series using the B-Field Unit:
If you perform a spatial matrix B field measurement using the B-Field
Unit, the measurement series will be terminated as soon as you connect
the E-Field Unit to the B-Field Unit. An audible signal will be heard.
• Measurement series using the E-Field Unit:
The connected B-Field Unit serves as the control unit during recording of
a spatial matrix measurement series with the E-Field Unit. The
measurement series ends automatically if you disconnect the E-Field
Unit from the B-Field Unit.
Operating sections
Operation is divided into two sections:
• “MEM MATRIX” sub-menu: Defining the spatial limits and the order of the
coordinates
• Matrix measurement screen: Display of measured value and target
coordinates, and operation of memory functions.
Note: Key F4 is used to switch between the two menus as required.
