Setting the "Lower Range Value" and "Upper Range
Value"
Menu path:
"Configure_Configure Pressure Measurement_Pressure"
The "Scaling" field offers two setting options.
1. Enter value:
Enter the desired values in the input fields "Lower Range
Value" and "Upper Range Value".
2. "Apply Process Variable":
For settings, apply the pressure for the "Lower Range Value"
and "Upper Range Value" to the measuring cell.
After the desired stabilized pressure is reached, press either
"Set lower Range value" or "Set Upper Range Value". Make
sure that the measuring limits are not exceeded.
Reducing stations with adjustable pressure and reference
displays can be used as pressure generators. When making
the connection, please ensure that there are no residual fluids
(for gaseous testing materials) or air bubbles (for fluid testing
materials) in the connection lines, since these can lead to
errors during inspection.
The possible measuring error of the pressure generator should
be at least three times smaller than the desired measuring
error of the transmitter.
Adjust damping
Menu path:
"Configure_Configure Pressure Measurement_Pressure"
Enter the desired damping value in the field "Output
parameter" in the line "Damping".
The additional time constant can be set between 0 s and 60 s
in increments of 0.0001 s.
Offset
Menu path:
"Configure_Configure Pressure Measurement_Pressure"
This function performs a parallel shift of the characteristic
curve so that it travels through a point specified by the user.
This makes it possible to set the output signal of several
measuring devices that measure the same process variable to
the same value without having to perform a calibration with
applied pressure.
For further information, see "Offset shift". Enter the respective
new X2 value (in %) in the window "The current measurement
value corresponds to".
Description
Menu path:
"Device_Identification_Device"
A measuring point tag with a maximum length of 16 characters
can be entered here. Characters can include uppercase
letters, numbers and a few special characters.
Factory reset
Menu path:
"Device_Reset_Reset to factory default"
Restores the transmitter settings to the factory default.
Warm start
Menu path:
"Device_Reset_Warm Start"
The transmitter is restarted with its basic settings. Temporary
settings such as "Simulating the current output" or "Diagnostic
messages" are reset.
IMPORTANT (NOTICE)
This action will briefly interrupt the connection.
