Description
Unit after
Linearisation
(V3H3)
Only for operation modes "Pressure%", "Level linear", "Level cylindrical horizontal"
and "Level manual".
Selects a level, volume or weight unit. The options depend on the selected operation
mode. The unit is only for display. The "Measured Value" (V0H0) is not converted to
the selected unit. Example: V0H0 = 55 %. After selection of the unit "hl", V0H0
indicates 55 hl.
(When you want to display the measured value (V0H0) converted into the selected
unit, enter the calculated value for the parameters "Display at 4 mA" (V3H1) and
"Display at 20 mA" (V3H2).) Refer also to Chapter 6.1, page 32.
Factory Setting: %
Density Factor
(V3H4)
Only for operation modes "Level linear", "Level cylindrical horizontal" and "Level
manual".
Using the density factor the output value and the "measured value" (V0H0) are
adjusted to a changed density of the liquid. The density factor results from the ratio
between "new density" and "old density". Refer also to Chapter 6.2.
Factory Setting: 1.0
Manual Level
(Linearisation)
(V3H6)
Only in operation mode "Level manual".
Selects the edit mode for the linearisation table.
Options: Activate Table, Manual, Semi-automatic and Clear Table.
Refer to Chapter 6.4 Linearisation.
Factory Setting: Clear table
Line No.
(V3H7)
Only in operation mode "Level manual".
Enter line numbers for the linearisation table.
Use the parameters "Line No." (V3H7), "Input Level" (V3H8) and "Set Volume" (V3H9)
to enter a linearisation table.
Number of lines in linearisation table: Min. = 2 and Max. = 21
Refer to Chapter 6.4 Linearisation.
Factory Setting: 1
Input Level
(V3H8)
Only in operation mode "Level manual".
Enter a fill value in the linearisation table. The input is in %. If you enter "9999.0" for
this parameter, you may delete individual points from the linearisation table. First
activate the linearisation table using the parameter "Manual Level" (V3H6). Refer to
this table, parameter "Line No." (V3H7) and Chapter 6.4 Linearisation.
Factory Setting: 9999.0 %
Set Volume
(V3H9)
Only in operation mode "Level manual".
Enter a volume value in the linearisation table. The input is in %. If you enter "9999.0"
for this parameter, you may delete individual points from the linearisation table. First
activate the linearisation table using the parameter "Manual Level" (V3H6). Refer to
this table, parameter "Line No." (V3H7) and Chapter 6.4 Linearisation.
Factory Setting: 9999.0 %
Current
(V7H0)
Displays actual signal current in mA. Refer to Chapter 7.2.
Simulation
(V7H1)
Simulation of a output signal current, e.g. to test the function of looped devices. Set
the simulation current using parameter "Set Simulation Current".
OFF: Current simulation off
ON: Current simulation on
Refer to Chapter 7.2
Factory Setting: OFF
Set Simulation
Current (V7H2)
Defines a simulation current.
The current can be simulated within limits of 3.6 mA to 22 mA.
Min. Current 4 mA
(V7H3)
Use this parameter to set the lower current limit.
(Devices partly accept no value less than 4.0 mA.)
OFF: Lower current limit = 3.8 mA
EIN: Lower current limit = 4.0 mA
Refer to Chapter 5.1 or 6.4, Section "4 mA level".
Factory Setting: OFF
Low Sensor
Trim
1)
(V7H4)
Enter the lower point of the sensor characteristic curve during recalibration.
Use this parameter to assign a new value to a reference pressure applied to the
device. The pressure applied and the value entered for "Low Sensor Trim"
correspond to the lower point of the sensor characteristic curve. Refer to Chapter 8.4
"Recalibration".
Factory Setting: "Low Sensor Limit" (V7H6)
1) The electronics check the input values for these parameters for compliance with editing limits,
refer to Chapter 7.4.
