2.1.1 PARAMETERS This starts a quick set-up procedure
applicable to most applications. The
supervisor can give the display language
(LANGUAGE), 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 77):
1 Do you have a completely filled tank?

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.

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.
