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
quicker update rate for fast response applications.
The bar graph is not used for square wave output, frequency, duty cycle, pulse
width, 4–20 mA% scale, 0–20 mA% scale and temperature measurements. When
frequency, duty cycle and pulse width are indicated on the primary display during
voltage or current measurement, the bar graph represents the voltage or current
