Normal operation

The E- and H-fields are measured
simultaneously during operation.

The larger of the two values is displayed.

If electromagnetic radiation is present, the
ESM “RadMan” indicates the magnitude of the
radiation level by means of four LEDs; alarms
are additionally signaled by a beep from the
loudspeaker.

Tip:

If you want to measure the E and H
fields separately when using your
ESM, switch the unit off and then on
again. The effective H field is displayed
briefly during step 3 of the switch on
routine. The effective E field is
displayed briefly during step 4 (see
page 19).

Display of measured values

12.5% LED

indicates: 12.5% of the power

density (= 35% of the field strength) permitted
by the relevant standard has been reached.
This state is indicated by a yellow LED.

25% LED

indicates: 25% of the power density

(= 50% of the field strength) permitted by the
relevant standard has been reached.
This state is indicated by a yellow LED.

50% LED

indicates

alarm state

: 50% of the

power density (= 70.7% of the field strength)
permitted by the relevant standard has been
reached.
