At this point, the start value of the measuring range is entered. This input acts
directly on the output signal. This does not affect the display directly.
The value range and its limits are displayed automatically.
In this works configuration, a so-called basic measuring range is defined for
each device. This basic measuring range is defined by the order code and is
stated on the type plate as 'Measuring range'.
With the parameters
Meas.range C1 start
and
Meas.range C1 end
the input range of measuring channel 1 is configured.
Spread (Turn down)
The characteristic can be spread within the basic measuring range. The spread
is the ratio of the basic measuring range to the set measuring span and may be
a maximum of 4:1. i.e. the difference of the two values
Meas.range C1
start
and
Meas.range C1 end
must be at least 25% of the basic meas-
uring range.

The spread of the characteristic only acts directly on the output signal. Activa-
tion of the parameter
Limit
also limits the display area to the set measuring
range.
Increase in the characteristic
If the
Meas.range C1 start
<
Meas.range C1 end
leads to a rising
characteristic. The output signal increases with the increasing pressure.
If the
Meas.range C1 start
>
Meas.range C1 end
, the character-
istic falls. The output signal drops with the increasing pressure.
