User can select the decimal points count of primary variable to display on LCD with DP menu. For
selecting the primary variable as displayed variable please refer to LCD parameters.

DP
(Decimal point for
show the primary
variable)
Press <M> until this page is appeared on LCD. Then press
<Z> to access the mapping mode (programing mode). You
can select the position of decimal point by pressing <S>.
After that, press <Z> until all characters blink. Then press
<M> for the saving new parameter and switching from
programing mode to operation mode.
If user select AUTO, according to momentary value of primary variable, the device determines
the number of decimal places.
3.2.2.4
Damping Value
User can determine the desired damping of primary variable and output signal using this
parameter. By setting of this parameter when the process pressure changes suddenly, the
primary variable and output signal will be change smoothly and will be reach to the changed
value after set damping value with a linear curve.

on sec))
Press <M> until this page is appeared on LCD. Then press
<Z> to access the amount of time based on second
(programing mode). You can change the amount of digits
by <S> and change the point and position of digits by <Z>.
After tuning this parameter, press the <Z> until all
characters blink. Then press <M> for the saving new
parameter and switching from programing mode to
operation mode.
The unit of damping value is second and the specified value cannot be negative or greater than
60 seconds.
3.2.2.5
Low Trimming
User can perform low-trim of device with local panel. Often, low-trim is used for offset calibration
of device which may be for removing of media temperature effect on pressure transmitter or
transmitter installation type.

change the point and position of digits by <Z>. After
tuning this parameter, press the <Z> until all characters
