Description
Enter protection level 2
Floating point format; default: +.00000000E+00. Enter the value

This item gives the offset to the water probe zero point in
relation with the tank zero point. Refer to section
5.2.1 how to obtain this offset value.
Format according to item LD (default: + 001.0000 m)
The water probe length (together with the water probe
bottom position) is required to calculate the water level. Refer to
section 5.2.1 which value needs to be entered.
One character: 'S' or 'D'. Only valid with 854 level gauges.
This item selects from which source the water level is measured
and transmitted in the level record (B-record) to the system.
S : from the water probe (VITO water sensor or side
mounted water probe)
D : from water dip (displacer)
Select 'S' for 854 the gauges (default: D).

With this item a water low alarm set point can be given.
When active, the water low alarm condition is signalled on the
instrument display in display format K (if display is available).
The water alarm information is also transmitted in the water level
record (M-record).
Format according to item LD (default: + 000.0100 m).
The water alarm hysteresis prevents the water alarm to be
switched on and off when the water level is around the water
high or water low alarm set point.
