Bar Graph
The analog bar graph functions like the needle on an analog
meter, but without the overshoot. The bar graph updates 30
times per second. Because the graph updates faster than the
digital display, it is useful for making peak and null adjustments
and observing rapidly changing inputs. For frequency, duty cycle,
pulse width, dBm, and crest factor functions, the bar graph
represents the amplitude of the input signal (volts or amps) and
not the value in the primary display. The bar graph is not shown
for capacitance, temperature, LoZ, AC+DC, AC over DC, peak,
or min max functions.
For dc voltage, dc current, and all relative percent modes, a
zero-centered bar graph is displayed. For dc voltage and current,
the bar graph range is the maximum of the selected range. For
relative percent mode, the bar graph goes to 10 %.
The number of lit segments indicates the measured value and is
relative to the full-scale value of the selected range. In the 50
Vac range, for example, the major divisions on the scale
represent 0, 5, 10, 15, 20, 25, 30, 35, 40, 45, and 50 Vac. An
input of 25 Vac turns on segments up to the middle of the scale.
For off-scale values,

the right end for positive off-scale values.
Status Bar Elements
The status bar at the top of the Meter’s display contains
indicators for battery level, time of day, mini-measurement
display, present date, and beeper on/off icon.
