Control Elements
Input jack for antenna cable. Do not sharply bend an-
tenna cable (see page 9 for best arrangement) or over-
tighten connector.
On/Off Switch (for battery operation only, without function when
powered by the analyser)

Power LED: lights up green in the case of sufficient
power supply
For battery operation, the device has an auto power off function.
To re-activate the meter after an automatic shutdown, simply turn
the device off and back on. While connected to the HF-Analyser,
e.g. for performing long-term data logging, the auto power off
function will be automatically disabled.
Power Supply
With the HF58B, HF58B-r or HF59B, no additional battery is
needed – the FF10 will be powered by the HF-Analyser. In this
case, the battery housing does not need to be mounted.
With the HFE35C, the filter battery supports the meter battery.
With the HF32D, HF35C, and HF38B, the filter is exclusively pow-
ered by the extra battery in the external battery housing.
A standard 9V alkaline-manganese or lithium battery placed in an
external battery box can directly supply the FF10 with power, this
way saving capacity of the meter battery.
Once the "ok" LED has gone off, a valid measurement can no
longer be guaranteed. If the filter LEDs also go off, the meter has
been automatically switched off by the auto power off function.
The auto power off function is automatically disabled if the filter
is powered by the HF-Analyser, for instance in the case of long-
term recordings.
