PRESENT FLUX
DENSITY READING
The flux density reading contains five or six digits of information and
includes the decimal point, polarity information, and the units of
measurement; see
Figure 6-1. The number of digits depends on the
update interval setting. The update interval is discussed later in this
section
. The present flux density reading is always displayed with a
larger text size than any other parameter. In the dc mode of
operation, the polarity is indicated with a “+” or a “-“. The polarity
information is absent when in ac mode, unless relative mode is
enabled. Relative mode operation is discussed later in this section.
Note: The reading displayed in ac mode will represent the true
rms value of the field waveform.

Note: The units of measurement for flux density may or may not
be displayed depending on screen orientation
MEASUREMENT
MODE INDICATOR The measurement mode is always displayed on a separate line, see
Figure 6-2. It indicates the measurement range, if autorange mode
is active, and whether ac or dc mode is selected. If autorange mode
is active the word “
Auto
” is displayed.
