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 to cater for fast- response applications.
For frequency, duty cycle, pulse width, 4 mA to 20 mA %
scale, 0 mA to 20 mA % scale, dBm, dBV, and temperature
measurements, the bar graph does not represent the primary
display value.
• For example, when frequency, duty cycle, or pulse width
is displayed on the primary display during voltage or
current measurement, the bar graph represents the
voltage or current value (not the frequency, duty cycle, or
pulse width).
• Another example is when 4 mA to 20 mA % scale ( ) or
0 mA to 20 mA % scale ( ) is displayed on the primary
display, the bar graph represents the current value and
not the percentage value.
