«Measurement» mode
A threshold that is outside the measuring range
is adjusted in such a way that it corresponds to
the lower (upper) range limit.
We recommend setting the threshold ½ decade
above the lower or ½ below the upper threshold
limit.
If both thresholds are outside the measuring
range, they are adjusted analogously in such a
way that a minimum hysteresis is achieved.
For logarithmic gauges, threshold values are
displayed in logarithmic or floating point format,
whereas for linear gauges, they are displayed
in floating point format only (→ Display formats
 35).
The modifications are automatically stored in non-volatile
memory.
