The ESM “RadMan” indicates
operational
readiness
every 10 seconds.
Operational readiness is indicated by an LED
which depends on the electromagnetic
radiation that has occurred or been measured.
This also allows the magnitude of the highest
measured value of electromagnetic radiation
to be read off
(Max Hold)
.

Brief flashing of the 12.5% LED means:
The highest measured value of
electromagnetic radiation was below 25%
of the power density permitted by the
relevant standard.

Brief flashing of the 25% LED means:
The highest measured value of
electromagnetic radiation was at least
25% of the power density permitted by the
relevant standard but was less than 50%
of the power density permitted by the
relevant standard.

Brief flashing of the 50% LED means:
The highest measured value of
electromagnetic radiation was at least
50% of the power density permitted by the
relevant standard but was less than 100%
of the power density permitted by the
relevant standard.

Brief flashing of the 100% LED means:
The highest measured value of
electromagnetic radiation was at least
100% of the power density (= 100% of the
field strength.
Tip:
Note the information regarding display
of measured values (see page 22).
