Some views do not offer an edit mode (for example when the software version is shown). In some
other views the (OK) key will start an immediate action (for example triggering the autotuning). Few
situations require a longer pressing of a key. However, everything will be explained in this manual
later.
4.2 Measurement Display
The various display options are explained in the following paragraphs.
Display Variant 1
– Magnetic Field Strength and Signal Quality
Besides the value of the magnetic field strength, an indication about the logging activity will be
displayed in the upper right corner (LOG=Logging without GPS; G-LOG=Logging with GPS):
In the lower right corner, the signal strength of the precession signal is displayed. The first number
shows the signal strength directly after the polarization phase, while the second number indicates
the strength after completion of the frequency measurement. These numbers are unit-less guidance
values to see if the measurements are reliable or disturbed. They can be compared only if the tuning
setting is not changed.
Display Variant 2
– Bar Graph
This view shows a simple bar graph visualizing either the difference to a reference value (will be
set by a 3 sec. long press of the (OK) key, see below) or the difference to the previous
measurement. The lower right corner shows the numerical difference, respectively.
In the upper right corner, the logging indicator will be shown, as mentioned above. If no logging is
active, the first signal amplitude value (the one directly after the polarization) will be shown.
If the value range of the selected bar graph (see below) is exceeded, the symbols "<" or ">" will be
shown. The value in the lower right corner will still show the correct difference.
