1 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 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).
The "–" sign indicates whether the measured or calculated value negative. Each
segment represents 33.34 or 200 counts depending on the range indicated on the
peak bar graph.
Table 1-9 Analog bar graph display
An unstable bar graph and unmatched primary display when measuring DC
voltage usually means the presence of AC voltages in the circuit.

Input terminals

The terminal connections for the different measurement functions of your
multimeter are described in the table below. Observe the rotary switch position of
your multimeter before connecting the test leads to the connector terminals.
Ensure that the probe accessories are connected to the correct input
