Temperature
The actual temperature at the sensor is shown
in V3H5.
Upper temperature limit
Exceeding the upper temperature limit of 80 °C
is shown in Field V3H5. Any value above 80 °C
is then stored in this field.

Lost echo delay time
Entering a delay time in V8H3 prevents an
alarm response of the measuring point to a
short-term losst echo (e. g. caused by foam).
For normal level applications, the delay time
should not be smaller than 30 s.
# VH Entry
1 V8H3 e. g. 80 H
The measuring point reacts to a lost echo only
after 80 s and then activates the alarm E 641.
Factory setting: 60 s
Selectable: 0 s ... 255 s
Actual height
Falsifications in height in V0H9 (e. g. by
temperature effects) can be corrected by
entering the correct height – the actual height
– in V3H1. Entering the actual height then
automatically corrects empty calibration.
First echo factor
Vessels with tightly rounded roofs (dome
covers) can cause double echoes giving rise to
a display showing a level which is too low.
Double echoes can be excluded by increasing
the first echo factor to »maximum«.
