Overview
Linearisation
0 = no linearisation
1 = cylindrical tank (horizontal)
2 = tank with bottom cone
3 = tank with spherical bottom
As standard the transmitter is delivered without linearisation (= 0). However, for a horizontal tank or a tank with a bottom
cone, a linearisation can be applied to achieve the current signal (mA) is equal to the level in the tank. All values must be
programmed in meters.

1. Push [PROG] until “100” is shown on the display.
2. Push
h
/ SPAN 11 times until “111” appears. (Confirm with [PROG])
3. Push
h
once. (Confirm with [PROG])
4. Enter the height (H1) of the tank in meters. (Confirm with [PROG])
5. Enter the same height (H2) of the tank in meters. (Confirm with [PROG])
6. Enter the length (L) of the tank. For a “ball” or cone shaped tank, take the cylindrical length plus the length of 1 “ball”
cone. (Confirm with [PROG])
7. Enter H3 in meters if the transmitter is installed like in the left picture. Enter 0m when the transmitter is installed like in
the right picture.
8. Enter the percentage of the actual “full” level (for example 80%).
(Confirm with [PROG]).
Note
If the height (H) of the tank is 1 meter and the maximum level in the tank is 0.8 meter the percentage (point 5) must be set
at 80%.
The calibration at P102 must be adjusted at: 1 meter (if s.g. equals 1)
