DISPLAY Display
SET 0% Sets the start value (as a numerical value in physical units)
Use the Z and S buttons to set the start value for the measuring range, and then
confirm the value by pressing the Z and S buttons simultaneously for at least 2 – 5
seconds. The display shows "OK".
SET 100% Sets the end value (as a numerical value in physical units)
Use the Z and S buttons to set the end value for the measuring range, and then
confirm the value by pressing the Z and S buttons simultaneously for at least 2 – 5
seconds. The display shows "OK".
SHIFT Zeros the display (in physical units (Zero point trim))
ZERO After setting and applying the reference pressure, press the Z and S buttons
simultaneously for at least 2 – 5 seconds in order to set zero the display and set output
signal 4 mA; the display then indicates "OK".
OFFSET Shifts the set span (only for DPT 200)
SHIFT This function can be used to shift the configured span to suit the application. This is
done by assigning a specified percentage value of the span to the acting pressure. The
size of the set span is not changed in the process. After invoking this function, the
display shows the acting value as a percentage of the span, and this can be
reconfigured accordingly.
Example: You require the range -10 ... 10 bar; your device has a differential pressure
range (dp) of 0 ... 20 bar:
After applying 0 bar, use the Z and S buttons to set +50%, and then confirm the value
by pressing the Z and S buttons simultaneously for at least 2 – 5 seconds.
You can now check the result under "VIEW":
6. Apply 0 bar;
7. Apply 10 bar;
8. Apply -10 bar;
9. Select SET 0%;
10. Select SET 100%;
DAMPING Sets the damping
Settable range: from 0.1 to 60 s
DISPLAY Selects the displayed variable
1 Measured pressure (unit)
2 Measured value in percent
3 Analogue signal display
UNIT Sets the pressure unit
Settable units: MPa, inH2O, inHg, ftH2O, mmH2O, mmHg, psi, bar, mbar, g/cm²,
kg/c² (abbreviation of kg/cm²), Pa, kPa, Torr, atm
Conversion of all pressure-related parameters is performed automatically.
FUNCTION Selects the function
Linear
Square root
SOFT VER Displays the program version (RSR101 R10)
EXIT Exits the menu
Press the Z+S buttons simultaneously to exit from the menu.
If no buttons are pressed for 60 seconds, the device returns to its normal operating
state.
