2.1.1 PARAMETERS This starts a quick set-up procedure
applicable to most applications. The
supervisor can give the tank height (TANK
HEIGHT), type of tank (TANK TYPE),
output function (OUTPUT FUNC.), current
output range (RANGE I), 4 mA setting
(SCALE 4mA), 20 mA setting (SCALE
20mA), error delay (ERROR DELAY) and
tag name (TAG NAME).
2.1.2 EMP.SPEC.REC
.
Fixed and moving objects in the tank cause
interference signals. Put them through this
filter to correctly measure the tank contents.
A quick set-up procedure will go through the
steps that follow (refer also to "How to make
a filter to remove radar signal interference"
on page 79):
1 Do you have a completely filled tank?
If the tank is full, it is not possible to
complete this procedure. The tank must be
partially filled or empty.
Yes [>], No []
2 Please, activate moving parts!
We recommend that you switch on moving
equipment to filter all interference signals.
OK [>]
3 Is your tank partially filled or empty?
If the tank is partially filled, the device must
include the tank contents when it filters the
signal.
Partially [>], Empty []
4 MEAS.DISTANCE
If the tank is partially filled, type in a
distance shorter than that between the
flange and the tank contents.
min-max:
0…tank height (2.3.1)
distance to
tank contents -
300 mm / 12¨
5 Emp.Spec.Type
Use the average value for tanks which
contain fixed objects only. Use the
maximum value for tanks which contain
many objects or moving objects.
Maximum, Average ?

7 Empty spectrum graph
This shows a set of spectra (signals found
in the tank). It also gives the amplitude and
location of each signal. Push [>] to make a
selection from the available spectra.
8 Do you want to save the empty spectrum
data?
Yes [>], No []
2.2.0 TESTS
2.2.1 SET OUTPUT This sets the current output to a test value
[mA]. The output will change to the given
value, independent of the measured value.
The current output will go back to the
measured value when the display goes
back to the menu level.
