Using the Bargraph
The bar graph is like the needle on an analog meter. It has an
overload indicator (
) to the right and a polarity indicator (
) to
the left.
Because the bar graph is much faster than the digital display,
the bar graph is useful for making peak and null adjustments.
The bar graph is disabled when measuring capacitance. In
frequency, the bar graph and range annunciator indicates the
underlying voltage or current up to 1 kHz.
The number of segments indicates the measured
value and is relative to the full-scale value of the
selected range
.
In the 60 V range, for example (see below), the major divisions
on the scale represent 0, 15, 30, 45, and 60 V. An input of
−
30
V turns on the negative sign and the segments up to the middle
of the scale.
