Cerabar S/Deltabar S Description of parameters (ToF Tool)
Endress+Hauser 95
POS. ZERO ADJUST
Entry
Position adjustment – the pressure difference between zero (set point) and the measured
pressure need not be known. (A reference pressure is present at the device.)
Due to the orientation of the device, there may be a shift in the measured value, i.e. when
the container is empty, the MEASURED VALUE parameter does not display zero.
Example:
– MEASURED VALUE = 2.2 mbar
– Correct the MEASURED VALUE via the POS. ZERO ADJUST parameter with the
"Confirm" option. This means that you are assigning the value 0.0 to the pressure
present.
– MEASURED VALUE (after pos. zero adjust) = 0.0 mbar
The CALIB. OFFSET parameter displays the resulting pressure difference (offset) by which
the MEASURED VALUE was corrected.
Prerequisite:
• This parameter is displayed for Deltabar S and Cerabar S with gauge pressure sensors.
Options:
• Abort
•Confirm
Factory setting:
0
POS. INPUT VALUE
Entry
Position adjustment – the pressure difference between zero (set point) and the measured
pressure need not be known. (A reference pressure is present at the device.)
Due to the orientation of the device, there may be a shift in the measured value, i.e. when
the container is empty, the MEASURED VALUE parameter does not display zero or the
desired value.
Example:
– MEASURED VALUE = 0.5 mbar
– For the POS. INPUT VALUE parameter, specify the desired set point for the
MEASURED VALUE, e.g. 2 mbar.
(MEASURED VALUE
new
= POS. INPUT VALUE)
– MEASURED VALUE (after entry for POS. INPUT VALUE) = 2.0 mbar
– The CALIB. OFFSET parameter displays the resulting pressure difference (offset) by
which the MEASURED VALUE was corrected.
CALIB. OFFSET = MEASURED VALUE
old
– POS. INPUT VALUE,
here: CALIB. OFFSET = 0.5 mbar – 2.0 mbar = – 1.5 mbar)
Prerequisite:
• This parameter is displayed for Cerabar S with absolute pressure sensors.
Factory setting:
0.0
EMPTY CALIB.
Entry
Enter level value for the lower calibration point (container empty).
The container is either empty or part full. By entering a value for this parameter, you are
assigning a level value to the pressure present at the device.
Prerequisite:
• LEVEL MODE = linear or height linearized (→ see also Page 103),
CALIBRATION MODE = wet (→ see also Page 108)
Factory setting:
0.0
FULL CALIB.
Entry
Enter level value for the upper calibration point (container full).
The container is either completely or almost full. By entering a value for this parameter,
you are assigning a level value to the pressure present at the device.
Prerequisite:
• LEVEL MODE = linear or height linearized (→ see also Page 103),
CALIBRATION MODE = wet (→ see also Page 108)
Factory setting:
100.0
