Power LED: lights up green in the case

For battery operation, the device has an
auto power off
function. To
re-activate the meter after an automatic shutdown, simply turn the de-
vice off and back on. While connected to the HF-Analyser, e.g. for per-
forming long-term data logging, the auto power off function will be au-
tomatically disabled.
Power Supply
With the HF58B, HF58B-r or HF59B
, no addition-
al 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 ex-
tra battery in the external battery housing.
A standard 9V alkaline-manganese or lithium bat-
tery placed in an external battery box can directly
supply the FF10 with power, this way saving ca-
pacity of the meter battery.
Once the
“ok“ LED
has gone off, a valid meas-
urement 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 disa-
bled if the filter is powered by the HF-Analyser, for
instance in the case of longterm recordings.
