5.2.4 Current Output Scaling
This programming mode is the simple and fast way to modify the scaling of the current
output.
For changing all parameters other than those assigned to 4 and 20 mA use either the QUICKSET
(5.2.2). or the Full Parameter Access (5.2.3).
Current Output Scaling mode is useful for re-scaling i.e. for modifying of the minimum and
maximum level assigned to the output signals 4 and 20 mA, if other than the factory default.
Current Output Scaling is aided by 2 screens for setting.
The instructions for this programming can also be found below the screw cover on the front panel
of the Echotel.
Note: For this programming the Echotel has to be in level measurement mode. See chapter 6.1

+ UP
(press for 3
seconds)
Enter or exit Current Output Scaling programming mode
UP / DOWN Increase/decrease blinking digit or scroll up/down
NEXT Move left with the blinking digit
UP + DOWN "GET LEVEL" - display actual level value measured by the Echotel
ENTER E Save actual value on the screen and move to the next screen
NEXT + UP Quit Current Output Scaling without saving the modifications
NEXT + DOWN Display Factory Default of the relevant screen
Screens Actions
4 represents the output signal
x = level value to be assigned
4 mA xxxx :– level value assigned to 4 mA current output
Manual: set required value (by UP / DOWN / NEXT keys) and save it (by the key ENTER
E
)
Automatic: use the “GET LEVEL” function (UP + DOWN ) to obtain actual measured value
with level in
tank or a fix target, e.g. wall. (“GET LEVEL” functions only if ECHO LED is lit) and save
it as above.
DEFAULT: 0 m (0%, Empty tank)
20 represents the output signal
x = level value to be assigned
20 mA xxxx : – Level value assigned to 20 mA current output
Manual: set required value (by UP / DOWN / NEXT keys) and save it (by the key ENTER
E
)
Automatic: use the “GET LEVEL” function (UP + DOWN ) to obtain actual measured value
with level in tank or a fix target, e.g. wall. (“GET LEVEL” functions only if ECHO LED is lit) and
save it as above.
DEFAULT: max. level = max. measuring distance - dead band (100%, Full tank) See chapter 5.1
