Introduction
Analog bar graph
The analog bar emulates the needle on an analog multimeter, without displaying
the overshoot. When measuring peak or null adjustments and viewing
fast-changing inputs, the bar graph provides a useful indication because it has a
faster updating rate
For frequency, 4-20 mA % scale, 0-20 mA % scale, and temperature
measurements, the bar graph does not represent the primary display value.
For example, when frequency is displayed on the primary display during voltage
or current measurement, the bar graph represents the voltage or current value
(not the frequency value). Another example is when the 4-20 mA % scale or 0-20
mA % scale is displayed on the primary display, the bar graph represents the
current value and not the percentage value.
The "+" or "–" sign indicates whether the measured or calculated value is positive
or negative. Each segment represents 250 counts based on 10000 counts
depending on the range indicated on the peak bar graph.

Range
An unstable bar graph and unmatched primary display when measuring DC
voltage usually means the presence of AC voltages in the circuit.
