1)
Volume control for the audio analysis
2)
Jack, 3.5 mm: AC output for the modulated part of the signal,
for audio analysis via PC or headset (mono).
3)
Normed 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 pa-
rameters 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.
5)
Measurement ranges
max
= 19.99 mW/m²
(= 19,990 μW/m²)
med
= 199.9 μW/m²
min
= 19.99 μW/m²
Scaling differs when applying an amplifier or damper!
6)
Selector switch for signal evaluation. Standard setting: “Peak”.
In the Peak hold mode you can choose a time setting for the
droop rate (Standard = “+”). The Peak hold value can be manu-
ally reset by pressing (14) “clear”.
7)
A little bar on the very left of the LCD indicates the unit of the
numerical reading:
bar on top =
m
W/m² (Milliwatts/m²)
bar on bottom =
μ
W/m² (Microwatts/m²)
8)
DC output for additional instruments, e.g. data logging devices
for longterm recordings (1 V DC full scale, scalable to 2 V DC).
9)
Connecting socket for antenna cable. The antenna is inserted
into the cross slot at the top side of the instrument.
10)
Power Level Adapter Switch for external optional amplifier or at-
tenuator only
(these are not part of the standard scope of supply)
. For
regular use of the instrument, the switch should be in pos. “0
dB”.
(Any other position will shift the decimal point to an incorrect position)
.
11)
ON/OFF switch.
.
.
= On with audio analysis mode.
12)
Load indicator
13)
Signal fraction: “Full” = total signal strength. “Pulse” = pulsed/
amplitude modulated part of the signal. The latter setting mini-
mizes the instrument’s noise to a fraction of the normal level (of
importance for particularly small signals).
14)
Push button to reset peak hold.
(Push and hold for 2 seconds or until
the reading no longer drops)
15)
Switch for selection of the Video Bandwidth.
Standard setting:
“VBW Standard”
Switches for rarely used functions are recessed in the casing of the
instrument.
