Expert Opinion
ing proposition in the me-
ter market. We don’t know
of any other meter that can
be used for evaluating, pro-
gramming and documenting
SCR and JESS systems the
way the KWS VAROS 109
does. KWS has truly gone out
of its way to whizz up a meter
that meets all requirements,
and then some…
And the list goes on: A log-
ging function is extremely
important with professional
meters. After all, many cus-
tomers want to see in writ-
ing what state their reception
system is in and demand a
printed log report.
As it is frequently neces-
sary to measure the sig-
nal parameters of the same
transponder at various an-
tenna outlets throughout a
building, a top-notch meter
must be able to do such re-
petitive jobs automatically.
How does the KWS VAROS
109 fare in that regard? Well,
installers can easily add any
transponder to the internal
memory of the KWS VAROS
109. The memory can store a
total of 99 transponders and
the list can be sorted accord-
ing to frequency, range or
satellite if required. In addi-
tion, each memory position
can be locked so that it can-
not be deleted accidentally.
Whenever a series of meas-
urements is to be performed
on a reception system the
installer only has to call up
the data logger, enter the
start and end positions in the
tuning memory and the KWS
VAROS 109 will automatically
measure the selected tran-
sponder. An XML file is cre-
ated for each measurement
series. The files can then be
opened and worked with on
any PC using Microsoft Ex-
cel or OpenOffice Calc. We
believe it’s a smart move by
KWS to use an open file for-
mat for log files as this allows
for much more versatile data
processing.
Installers dealing mainly
with satellite reception now
don’t have an excuse any
longer for not using a pro-
fessional meter by KWS. The
VAROS 109 is a fully-fledged
meter, but with a price tag
that is as small as its size. If
you’re an experienced DXer
or even a hobby installer
without your own business
you should also give this new
offering by KWS some seri-
ous consideration.
Many companies already
use KWS meters of the AMA
or VAROS ranges, and even
they have good reason to
equip their installers with the
new KWS VAROS 109 hand-
held meter for their daily rou-
tines. Its small dimensions
coupled with low weight and
long battery life make it an
ideal companion for installa-
tion jobs.
The meter offers all fea-
tures and functions required
for installation, maintenance
and fault clearance and once
you start using it you’ll never
want to give it away again.
Not only does it provide
measurements with utmost
precision, it is also extremely
easy and convenient to use.
So can it be true that for
once we have nothing to crit-
icise? If you press us really
hard, there is actually one is-
sue that we have: The nylon
bag and – even more impor-
tantly – the hard case don’t
show a huge KWS logo. This
is a shame, since customers
won’t know right away that
their installation job will be
performed by a profession-
al with the best equipment
available.
