Using the Bar Graph

The bar graph is like the needle on an analog meter. It has an
overload indicator (>) to the right and a polarity indicator ( ) to the
left.
Because the bar graph updates about 40 times per second, which
is ten times faster than the digital display, the bar graph is useful
for making peak and null adjustments.
The bar graph is disabled when measuring capacitance. In
frequency, the bar graph and range annunciator indicate the
underlying voltage or current.
The number of segments indicates the measured value and is
relative to the full-scale value of the selected range, except on the
10 A ranges.
In the 60 V range, for example (see below), the major divisions on
the scale represent 0, 30, and 60 V. An input of 30 V turns on
the negative sign and the segments up to the middle of the scale.

Cleaning

Wipe the case with a damp cloth and mild detergent. Do not use
abrasives or solvents. Dirt or moisture in the terminals can affect
readings.
