Battery Management - Gigahertz Solutions HF59B Instruction Manual

Digital High Frequency Analyser HF59B
Further Analysis /
Optional Accessories:
Gigahertz Solutions offers a range of pream-
plifiers and attenuators, to widen the range of
power densities which can be processed
with this instrument, See section Quantitative
Measurement.
Furthermore there are two variable frequency
filters ("variable traps") for quantitative sepa-
ration between different sources of radiation.
One of them blocks the selected frequency
by 20 dB to one hundredth of its real inten-
sity; the other version blocks by 40 dB for a
more accurate reading.
Future developments for this instrument:
1. A digital extension module,
amongst other features will enable to dis-
play the results in other units, like e.g.
V/m and widen the range displayable to
49990 instead of the present 19990
digits.
2. A digital internal extension module for
recording of single readings or for a long
term series of readings (data logging) in-
cluding PC software for their evaluation.
Antenna / Aerial for lower frequencies
For measurement of signal frequencies
above 27 MHz (including: CB radioing, ana-
logue and digital TV and radio TETRA etc.)
we offer the compact quasi isotropic Ultra
Broad Band Aerial UBB27 with a range from
27 MHz to far into the Gigahertz range. It is
included in the HFE59B-kit.

Instrument for yet higher frequencies
For the analysis of yet higher frequencies (up
to about 6 GHz, i.e. WLAN, WIMAX and
some directional radio sources and flight
radar) the HFW35C is available from Giga-
hertz Solutions. Frequencies below 2.4 GHz
are being suppressed by this instrument to
ensure precise analysis of these higher fre-
quencies
Available for low frequencies:
Electrosmog is not limited to the Radio Fre-
quency range!
Also for the low frequency range such as
power (distribution and domestic installa-
tions) including their higher harmonics we
which
offer a broad range of affordably priced in-
struments with high professional standards.
Please refer to a list of contacts is at the end
of this brochure.

Battery Management

Conditioning of the internal rechargeable
battery
The instrument comes with a rechargeable
internal NiMH-Battery. This should be condi-
tioned to achieve its maximum capacity.
Please proceed as follows:
1. Plug the included, 2.5mm adapter con-
nector into either the AC or DC output.
This will deactivate the automatic power
off function. Switch on the meter until it
turns off (which happens automatically
shortly before the battery is damaged by
"deep discharging")
2. Connect the AC-Power adaptor. The
green "Charging" LED should turn on. If
not, switch the analyzer on and then off
until it turns on.. After 10 to 13 hours the
charging process will finish automati-
cally. When charging is complete, the
green LED will turn off automatically.
3. Repeat this procedure one or two more
times. Repeat every few months to
maintain maximum charging capacity.
The rechargeable battery will thank you with
a longer life and a full capacity.
