So messen Sie mit Ihrem
Meter-Master
The Meter-Master measures the
distance between two points and/or
surfaces by means of emitting and
reflecting ultrasonic waves. You can
chose between measurement results
in cm, feet and feet/inches. These are
determined by the MODE key. In
addition the Meter-Master can work
out the square area from two given
measurements (X.Y) and the cubic
area from three given measurements
(X.Y.Z). where possible put the end of
the Meter-Master housing at one of
the two end-points of the distance to
be measured (e.g. wall or floor). The
length of the housing will be
automatically added on.
How to calculate lengths:
You start the measurement by pres-
sing either of the two ON Keys on
the sides. Four bleeps will announce
that the measurement has been con-
cluded. The display will show the
measurement value for 10 seconds. It
will be stored and can be accessed by
RECALL. As needed, you can clear the
memory by means of the CLR SUM
Key. The appliances always turns itself
off.
How to calculate the surface areas
of floors, walls and ceilings etc.:
· Measure the length and store with
the X Key · measure the length and
store with the Y Key · when you
press on X.Y the square area will be
shown - the display will show the
word
SQUARE.
How to calculate the cubic
measurement of a space:
· Measure the length and store with
X · measure the width and store with
Y · measure the height and store with
Z · when you press on X-Y-Z the cubic
volume of the space will be shown -
the word CUBE will be shown in the
display.
How to measure using the addi-
tion of partial measurement
lengths over 15 m.:
· Clear the memory by pressing CRL
SUM · measure the first segment of
the length · store with SUM ·
measure the second segment of the
length · store with SUM · the display
will now show the total sum of both
measurements · this procedure will
work up to an overall length of
9,999.99 m.
Some Useful Tips
· Should the display show LO BAR,
then your appliance needs 2 new
batteries (3V CR 2032).
· The field of measurement must be
free of obstacles. There must be no
objects (e.g. your arm or a ladder)
within an angle from the appliance of
± 7°. o The ultrasonic beam does not
penetrate through glass (window
panes). o When measuring through
doorways and openings in walls it is
safer to take two or three
comparative measurements from
differing positions. o The distance to
be measured must be a minimum of
61 cm: below this level wrong results
will be shown.
· Should the display show ERROR
then it means that no clear distance
signal has been received. If the target
is at a distance of more than 15 m
then partial measurements should be
carried out. o Carpets, upholstery and
curtains do not reflect ultrasonic
beams very well. In such cases it is
better to use smooth measurement
media such as shelves, mirrors, paint
buckets etc.
· The ultrasonic sensor has been
calibrated in a measurement
laboratory and has afterwards been
sealed. The appliance compensates
for varying room temperatures during
the measurement process.
In cases where a change of location
involves great differences in
temperature it will need a short
adjustment time before being used.
Discrepancies of air pressure and the
influence of humidity can lead to dis-
tortions in the measurements: the
noise of wind and other noise sources
can lead to false results.
· Clean with a soft cloth. Make sure
that no water penetrates into the
housing.
