CUST. UNIT FACT. M (703)
Entry
Enter conversion factor for a customer-specific mass unit.
The conversion factor must be entered in relation to the SI unit "kg".
See also CUSTOMER UNIT M.
Prerequisite:
• LIN. MEASURAND = Mass, MASS UNIT = User unit
Example:
– You want the measured value to be displayed in "buckets".
– MEASURED VALUE = 10 kg
i
1 bucket
– Entry CUSTOMER UNIT M: bucket
– Entry CUST. UNIT FACT. M: 0.1
– Result: MEASURED VALUE = 1 bucket
Factory setting:
1.0
CALIBRATION MODE (392)
Selection
Select calibration mode.
Options:
• Wet
Wet calibration takes place by filling and emptying the container. This calibration mode
requires two pressure-level value pairs to be entered. In the case of two different levels,
the level value is entered and the pressure measured at this moment is assigned to the
level value.
See also the following parameter description for EMPTY CALIB.,
EMPTY PRESSURE, FULL CALIB. and FULL PRESSURE.
• Dry
Dry calibration is a theoretical calibration which you can carry out even if the device is
not mounted or the container is empty.
– For the "Level" measured variable, the density of the fluid (
see Page 74, ADJUST
DENSITY) must be entered.
– For the "Volume" measured variable, the density of the fluid and the tank volume
and tank height must be entered (
see Page 74, ADJUST DENSITY, TANK
VOLUME and TANK HEIGHT).
– For the "Mass" measured variable, the tank volume and the tank height must be
entered (
see Page 75, TANK VOLUME and TANK HEIGHT). The density must
also be entered in the case of a zero point shift (level offset) (
ADJUST DENSITY).
– For the "%" measured variable, the density of the fluid must be entered and a level
assigned to the 100 % point (
see Page 74 and 77, ADJUST DENSITY and 100%
POINT).
If the measurement should not start at the mounting location of the device, a level
offset must be entered (
!
Note!
LIN. MEASURAND: "% (Level)", "Mass" and "Volume":
If the change to dry calibration is made after a wet calibration, the density must be
entered correctly using the ADJUST DENSITY and DENSITY PROCESS parameter before
changing the calibration mode.
See also Page 97.
Factory setting:
Wet
EMPTY CALIB. (314)
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.
See also EMPTY
PRESSURE.
Prerequisite:
• CALIBRATION MODE = Wet
!
Note!
For this parameter, the on-site display shows the level value to be entered and the
pressure present at the device. In order for the level value to be saved together with the
pressure present at the device, the entry field for the level value must first be activated
using the "+"- or "–" key before confirming with the "E" key. This applies also if the level
value is to remain unchanged.
Factory setting:
0.0
