Measure
The instrument can operate in one of four electromagnetic field
level measurement modes:
● EMF in LIVE BUILDING
● EMF in LIVE AREA
● EMF of PC
● View
"EMF in LIVE BUILDING", "EMF in LIVE AREA", and "EMF
of PC" modes have preset thresholds for audible, color and text warning
triggering according to the norms (Table 2).

When the threshold limit is exceeded, a corresponding message is
displayed on the red background and an interrupted alarm sounds. The signal
can be enabled or disabled by the "Alarm" parameter setting

The average measurement time is 500 ms. Measurement data are
averaged (averaging degree for each measurement mode is specified in the
Table 2). A root-mean-square value of all values along measurement axes is
displayed as an electric and magnetic field intensity. An instant value for
each measurement along each axis is also displayed in a form of graphic
column (page 33).
A limit of column filling in different modes is specified in the

The instrument is equipped with two antenna sensors for
measurement of electric field along X and Y axis and with three sensors for
magnetic field measurements along X, Y, and Z axes. The axes correspond to
the axes of three-dimensional orthogonal coordinate system. The figure
displays the location of the axes with relation to the instrument image.
During the source search it is essential to analyze the instant
values along individual axes for the purpose of source direction identifica-
tion.
The switching between modes is performed circle-wise by
pressing the right button, [NEXT].
