Analogue Bar Graph Display
The analogue bar graph likes the needle in a traditional
analogue meter (AMM). It refreshes 50 times a sec,
which is 10 times faster than that of digital display and
is applied to zero adjustment and observation of rapidly
changing signal that make digital display hard to read.
The analogue display is divided uniformly into 10 scales
and composed of 41 segments; of which the full-range
value corresponds to the full-range value of the
measurement range that has been selected. The polarity
of the measured value is displayed as "-" on the left of
the analogue display: positive polarity is not displayed.
For example, when 80V range is selected, the full-range
value of the analogue display is 80V, and as the full
range is uniformly divided into 10 grades, each grade
denotes 8V; If the input is 40V, the high-lighted bar-shape
will be at the position indicated by the number 5. if the
input is -40V, a "-" sign will appear on the left of the
analogue display.
There is no analogue displaying value when making
measurement of frequency, diode, conductance and
capacitance.
