Parameter
Description
Software No.
(V2H2)
Indicates the device and software number.
The first two digits represent the device number and digits 3 and 4 the software
version. Cerabar S HART with SW 7.1 = 6571
Peak Hold P Min
(V2H3)
Indicates the smallest measured pressure value (maximum pointer).
This parameter is reset to the current pressure value when you confirm by pressing
the ENTER key.
Peak Hold P Max
(V2H4)
Indicates the largest pressure value measured (maximum pointer).
This parameter is reset to the current pressure value when you confirm by pressing
the ENTER key.
Internal Counter
High
(V2H5)
This counter indicates how often a measured pressure was above the upper sensor
limit (V7H7). Maximum value = 255
This parameter is reset to zero when you confirm by pressing the ENTER key.
Sensor
Temperature
(V2H6)
Indicates the current temperature measured. The unit for displaying the temperature
is selectable using the parameter "Temperature Unit" (V7H9).
Peak Hold T Min
(V2H7)
Indicates the lowest temperature measured (maximum pointer).
This parameter is reset to the current temperature value when you confirm by
pressing the ENTER key.
Peak Hold T Max
(V2H8)
Indicates the largest temperature measured (maximum pointer).
This parameter is reset to the current temperature value when you confirm by
pressing the ENTER key.
Default Values
(Reset)
(V2H9)
Enters a reset code. Possible reset codes include: 5140, 2380, 731, 62 and 2509.
Chapter 7.3 lists the parameters which the reset codes reset to the factory settings.
Operation Mode
(V3H0)
Select the operation mode:
– Pressure: for linear pressure measurements. The measured value (V0H0) indicates
the pressure in the selected pressure unit (V0H9). Refer to Chapter 5.
– Pressure %: for linear pressure measurement. The measured value (V0H0) is
calculated and displayed in %. Refer to Chapter 5.
– Level linear *: for level, volume or weight measurements for standing tanks. The
level is linear to the measured pressure. Refer to Chapter 6.
– Level cylindrical horizontal *: for level, volume or weight measurements with
cylindrical horizontal tanks. The volume or the weight is not proportional to the
level. A linearisation table is integrated. Refer to Chapter 6.4.
– Level manual *: for precise volume or weight measurement where the volume or
weight is not proportional to the level or to the measured pressure, e.g. tanks with
conical outlet. Use the parameters "Line No." (V3H7), "Input Level" (V3H8) and
"Set Volume" (V3H9) to enter a linearisation table. This linearisation table is used to
calculate the output signal. Refer to Chapter 6.4.
– Disabled: Check the position of the damping switch in the device. The switch
positions 8…F are not available. Refer to Chapter 4.2.
Factory Setting: pressure
* In these modes, the measured value (V0H0) factory setting is displayed in %. To
obtain a better presentation, use the parameters "Unit after Linearisation" (V3H3) to
select a level, volume, weight or flow rate unit. Refer to the parameter description of
"Unit after Linearisation" (V3H3).
Display at 4 mA
(V3H1)
Only for operation modes "Pressure%", "Level linear" and "Level cylindrical horizontal".
Enter a value for the measuring point "Level empty".
The value is assigned to the 4 mA calibration point "Set 4 mA Value" (V0H1).
The parameter is displayed as standard in %. To obtain a better presentation, select
a different unit using the parameter "Unit after Linearisation" (V3H3).
Factory Setting: 0%
Display at
20 mA
(V3H2)
For operation modes "Pressure%", "Level linear" and "Level cylindrical horizontal".
Enter a value for the measuring point "Level full".
The value is assigned to the 20 mA calibration point "Set 20 mA Value" (V0H2).
The parameter is displayed as standard in %. To obtain a better presentation, select
a different unit using the parameter "Unit after Linearisation" (V3H3).
Factory Setting: 100%
