Slightly loosen screw 2 just enough for the
alignment mechanism to be able to move in
the vertical direction. Note that the signal
strength will typically drop slightly when
screw 2 is loosened. If the value drops
significantly, it can be helpful to reset the
maximum recorded signal strength by
entering #AM on the HART® terminal.
12
Align in vertical direction by turning screw 4.
As for the horizontal alignment, turn very
slowly in the direction whereby the signal
increases. After reaching the maximum and
the signal starts to drop turn back until the
signal is back close to the maximum.
13
Tighten screw 2.
14
Store the current signal strength (absolute
transmission) and exit Alignment mode by
entering the following command in the
HART® terminal:
#SAV
Terminal response:
SM:OK
Saves the current settings, exits
Alignment Mode and enters
Service mode.

Set the elevation above sea level by entering:
#MW 0 <altitude in meters>
For example, for a setting of 100 meters
above sea level, the syntax is: #MW 0 100
Note! The height should be in whole meters.
Terminal response for the left
example:
REGISTER 0(ALTITUDE)=100
The accuracy of the height should
be better than ±350 meters.
16
Set the distance between the TX and RX by
entering the following command:
#MW 1 <path length>
For example, for a 15 meter path, the syntax
is: #MW 1 15
Note! The length should be in whole meters.
Terminal response:
REGISTER 1(PATH_LENGTH)=15
