Alarm threshold at the calibration
frequency

50% of standard value


Thresholds at 12.5%, 25%, 50% and
100% of standard value

The display is calibrated in terms of
relative power flux density. 50% of the
power flux density of the standard
corresponds to an E-field or H-field
strength of 70.7% of the limit value in the
relevant standard.

The E- and H-field components are
measured simultaneously. The largest
