Battery Management
The instrument comes with a rechargeable, high quality internal
NiMH-Battery. The quality of these high-capacity NiMH batteries (far
better than NiCd batteries, for instance) can be best maintained if
they are almost totally discharged (i.e. used) before being fully re-
charged (for > 13 hours or until the green charging LED turns off).
The loading procedure is started by switching the meter on and off
once only after connecting it to the power supply unit.
Changing the rechargeable Battery
The battery compartment is at the back of the analyser. To remove
the lid, press on the grooved arrow and pull the cap off.
Insert only
rechargeable batteries. If you use regular alkaline (non – re-
chargeable) batteries do not use a charger or AC-adapter!
Auto-Power-Off
This function conserves energy and extends the total operating
time.
4.
In case you have forgotten to turn OFF the HF analyser or it has
been turned ON accidentally during transport, it will shut off au-
tomatically after 40 minutes.
5.
If “low batt” appears vertically between the digits in the center
of the display, the HF analyser will turn OFF after 3 min in order
to avoid unreliable measurements. In that case charge the re-
chargeable battery.
6.
The built-in function, Auto-Power-Off, will automatically be de-
activated by plugging in a 2.5 mm DC. The function will also au-
tomatically be re-activated to prevent a total discharge of the
battery by further operation.
Mains operation
The HF analyser can also be supplied with power by using the
mains adapter (for instance for long-term measurements in combi-
nation with the NFA). When doing so, please take care to turn the
volume button right down to zero (“-”), otherwise you might hear the
50 Hertz noise of the mains volt-
age.
Interferences may, however, also
be caused by high frequency
couplings through the power
supply unit. This can easily be
tested by unplugging the power
supply unit from the meter while
in use. If the measurement value
now shows a significant drop, this
is a sign of an unwanted cou-
pling.
