2.4.0 OUTPUT I
2.4.1 OUTPUT FUNC. The output function. Select an output
function to scale the current values in
relation to a given point (usually the device
process connection or the tank bottom).
The output current value is shown on a bar
graph in normal mode if the measurement
name (displayed measurement) is the
same as the output function. Conversion
parameters (Distance Conversion, Level
Conversion) are shown if there is volume
or mass data in 2.8.1 INPUT TABLE.

2.4.2 RANGE I This menu item sets the limits of the
output current range to 1 of the 2 available
options: standard limits (4...20 mA) or
NAMUR NE 43-compliant limits
(3.8...20.5 mA). It also tells the device what
to do if an error occurs. if you set RANGE I
to 4-20/22E 4-20/22E 4-20/22E 4-20/22E and an error occurs (e.g. the
tank is too full, ...), the device output
current will change to an error value of
22 mA . If you set RANGE I to 4-20 4-20 4-20 4-20 and the
device senses a measurement error, the
value will stop at the last correct
measurement.

4-20/3.6E (If the
device is used in
safety-related
systems (SIL2),
do not use the
"4-20" setting)
2.4.3 SCALE 4mA This gives a measurement value to 4 mA. min-max: 1 This depends on
the probe type
2
2.4.4 SCALE 20mA This gives a measurement value to 20 mA. min-max: 1 This depends on
the probe type

2.4.5 ERROR DELAY The time after which the current output
changes to an error value. The error value
shows that there is a measurement error.

2.5.0 APPLICATION
2.5.1 TRACING VEL. Tracing velocity. This value must agree
with the maximum rate of change of the
level of the liquid or solid contents in the
tank.
min-max:
0.1…1000 m/min
10.0 m/min
2.5.2 AUTO Er CALC Automatic dielectric constant (ε
r
)
calculation. For measurement in TBF
mode. The device automatically calculates
the ε
r
value of the liquid or solid contents
in the tank.
YES, NO NO
2.5.3 GAS EPS. R Dielectric constant (ε
r
) of the gas in the
tank. A major parameter for TDR level
measurement devices. If the dielectric
constant of the gas is very different from
the default value (air), set 2.5.3 GAS EPS.
R to the ε
r
value of the gas.
min-max: 0.8...115.00 1
2.5.4 EPS.R CALCUL. The calculated ε
r
value for the liquid or
solid contents in the tank. The result of the
calculation in 2.5.2 AUTO EPSI. R. This
menu item will not be available if 2.5.2
AUTO EPSI. R is not used.
