5.2 Analog Indication
The analog indication with bar graph is updated 28 times per
second. Analog indication is of particular use when observing
variations of measured values. The analog bar graph (13) has
its own polarity indication in measuring DC quantities, when
the positive pole of the measured quantity is applied to the „ “
input terminal. Analog bar graph has 65 scale divisions so that
variations of the measured values around „zero“ can be
observed exactly. The overrange is indicated by the right trian-
gle (12) when measured value is > 6600 counts (for mea-
surement > 1999).
