Zero
Point
Adjustment
It
is
possible
to
enter
a
value
that
will
used
either
for
zero
point
calibration
or
low
flow
cut
off
.
Your
entered
value
will
be
use
as
zero
point,
if
you
choose
"Zero
Point".
The
sensor
will
start
counting
at
this
point.
This
adjustment
is
helpful
if
there
is
no
flow
in
the
pipe,
but
the
sensor
shows
some.
For
example:
Although
there
is
0,00
m3/h
flow
in
the
pipe
the
flow
meter
shows
0,08
m3/h.
Now
you
can
raise
up
your
zero
point
to
0,08
m3/h,
the
flow
meter
will
show
now
0,00
m3/h.
Your
entered
value
will
be
use
as
cut
off
value,
if
you
choose
"Low
Flow
Cut
Off".
All
measuring
values
below
this
value
won't
be
shown
at
the
display
of
the
KEC.
The
values
below
your
entered
value
also
won't
be
calculated
to
the
consumption
meter.
Even
the
4
‐
20
mA
output
will
set
to
zero
(4
mA)
and
there
won't
be
impulses.
For
Example:
Despite
the
closed
ball
valve,
8
m³
/
h
is
still
measured
in
the
supply
line
The
customer
set
the
low
flow
cut
off
at
10
m3/h.
The
display
and
the
impulse
outlet
now
show
zero
also
the
4
‐
20
mA
outlet
shows
zero
(4
mA).
