1) Volume control for the audio analysis (on/off switch
2) Jack, 3.5 mm: AC output for the modulated part of the signal, for
audio analysis via PC or headset.
3) Calibrated AC output 1 Volt peak-peak, proportional to the field
strength.
4) Jack, 12-15 Volt DC for charging the battery. AC adapter for 230
Volt/50 Hz and 60 Hz is included. For other Voltages/Frequencies
please get an equivalent local AC adaptor with the output param-
eters 12 – 15 Volt DC / >100mA.
Caution: If an alkaline battery is used, under no circumstances
should the power adapter be connected at the same time, other-
wise the battery may explode.
Measurement ranges
5)
max = 19.99 mW/m²
min = 1999 µW/m²
Scaling differs when applying the optionally available amplifier or damper!
6) Selector switch for signal evaluation. In the peak hold mode, you
can choose a time setting for the droop rate (Standard = "+"). The
peak hold value can be manually reset by pressing (13) "clear".
7) A little bar on the very left of the LCD indicates the unit of the nu-
merical reading:
bar on top = mW/m² (Milliwatts/m²)
bar on bottom = µW/m² (Microwatts/m²)
8) DC output, allows you to connect additional instruments, e.g. data
logging devices for long-term recordings. Scalable to 1 V DC full

9) Connecting socket for antenna cable. The antenna is inserted into
the cross slot at the front tip of the instrument.
