Checking the function
The sensor functions of the ESM “RadMan”
can be checked with the aid of a Test
Generator (BN 2244/90.38).
The H-field and E-field sensors are tested
separately.
1. Place the Test Generator in the vicinity of
the sensors.
2. Press the button on the Test Generator.
3. Switch on the ESM.
The self-test runs automatically.
4. Wait until the H-field sensor is checked
At least the 12.5% LED must light up.
5. Wait until the E-field sensor is checked.
At least the 12.5% LED must light up.
6. Switch off the Test Generator.
Tip:
Switch the Test Generator off before
you hear the double “beep”, otherwise
the ESM “RadMan” will save the
measured value of radiation (Max
Hold).
If you switch off the Test Generator
after the double “beep”, switch the ESM
“RadMan” off and then on again to
clear the Max Hold state.
