Control Elements; Power Supply - Gigahertz Solutions FF10 Mode D'emploi

.English.

Control Elements

Input jack for antenna cable. Do not sharply bend
antenna cable (see page 9 for best arrangement) or
overtighten connector.
On/Off Switch (for battery operation only, without function
when powered by the analyser)
ok Power LED: lights up green in the case of sufficient

power supply

For battery operation, the device has an auto power off func-
tion. 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
powered 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.
