CAUTION:
Choose
values
as
near
as
possible
to
the
bottom

top
of
your

achieve

Multi‐point
Scaling
If
an
input
is
connected
to
a
linear
input
signal
(mA,
mV
or
VDC),
multi‐point
scaling
can
be
enabled
for
that
input
to
allow
linearization
of
a
non‐linear
signal.
–
see
Input
Configuration
Sub‐Menu.
The
Scale
Input
Upper
&
Lower
Limits
define
the
values
shown
when
the
input
is
at
its
minimum
and
maximum
values.
Up
to
15
breakpoints
can
scale
the
input
vs.
displayed
value
between
these
limits.
It
is
advisable
to
concentrate
the
break
points
in
the
area
of
the
range
with
the
most
non‐linearity,
or
an
area
of
particular
importance
to
the
application.
To
use,
set
the
scale
limits,
and
then
enter
the
1st
scaling
point
(this
is
a
%
of
the
scaled
input
span,
and
the
desired
display
value
to
be
shown
at
that
input
value.
Next
set

Calibration
Reminder
A
calibration
reminder
can
be
set
if
Data
Recorder
option
is
fitted
(which
means
instrument
has
battery‐backed
Real
Time
Clock).
The
addition
of
a
clock
means
that
the
instrument
can
be
aware
of
the
date
and
time
(even
when
powered
down).
This
information
can
be
used
to
remind
the
user
to
calibrate
the
inputs
at
a
specified
future
date.
The
date
is
set
in
the
Input
Configuration
menu.
If
enabled
and
the
date
set
is
exceeded,
a
calibration
due
screen
is
shown
every
24hrs
(and
at
every
power‐up)
until
it
is
changed
to
a
future
date
(or
disabled).
Calibration
Low
Process
Value
This
example
shows
a
positive
Low
Offset
and
a
negative
High
Offset.
For
example:
If
the
process
displays
+0.5
at
the
low
end,
an
offset
of
‐0.5
would
change
the
value
to
0.0
A
high
end
value
of
98.3
with
a
+1.7
offset
would
read
100.0.
There
is
a
linear
relationship
between
these
two
calibration
points.
