Remediation And Shielding; Warranty - Gigahertz Solutions HF59B Instruction Manual

Digital High Frequency Analyser HF59B
Changing the rechargeable Battery
The battery compartment is at the back of
the analyzer. To remove the lid, press on the
grooved arrow and pull the cap off. Insert
only rechargeable batteries. If you use
regular alkaline (non – rechargeable) bat-
teries do not use a charger or AC-adapter!
Auto-Power-Off
This function conserves energy and extends
the total operating time.
1. In case you have forgotten to turn OFF
the HF analyzer or it has been turned ON
accidentally during transport, it will shut
off automatically after 40 minutes of con-
tinuous use.
2. If "low batt" appears vertically between
the digits in the center of the display, the
HF analyzer will turn OFF after 3 min in
order to avoid unreliable measurements.
In that case charge the rechargeable
battery.
3. The built-in function, Auto-Power-Off,
will only be de-activated by plugging in a
2.5mm jack into one of the output sock-
ets AC or DC, see "Conditioning..." two
sections up. The function will be re-
activated to automatically prevent total
discharging of the battery by further op-
eration.

Remediation and Shielding

Please call us or send us an e-mail.
We will assist you in any shielding project
you might have.
The shielding effect of the various materials
is stated normally in "- dB", e.g. "– 20 dB".
Conversion of shielding effect into reduction
of power density
„-10dB" is measured value divided by 10
"-15dB" is measured value divided by ~30
"-20dB" is measured value divided by 100
"-25dV" is measured value divided by ~300
"-30dB" is measured value divided by 1000
etc.
Please be aware of the manufacturer's notes
about the normally achievable shielding ef-
fects, as 100 % shielding is almost always
impossible. Partial shielding reduces the at-
tenuation considerably. That is why shielding
of seemingly radiation tight adjacent areas is
highly recommended.

Warranty

We provide a two year warranty on factory
defects of the HF analyzer, the antenna and
accessories.
Antenna
Even though the antenna appears to be
rather delicate, it is made from a highly dura-
ble FR4 base material that can easily with-
stand a fall from table height.
HF Analyzer
The analyzer itself is not impact proof, due to
the comparatively heavy battery and the
large number of wired components.
Any damage as a result of misuse is ex-
cluded from this warranty
