D
IGITAL COMMUNICATION
P19: - - - a Short (HART) address of the unit
FACTORY DEFAULT: 0
Addresses 0…63 are, as per the HART standard, for distinguishing units in the same loop.
•
Address 0: current loop output of 4…20 mA is operational
•
Address 1…15: current output is fixed 4 mA.

EASUREMENT OPTIMIZATION
P20: - - -
Damping
FACTORY DEFAULT: 60 s
For testing only Applicable
Damping time damps unwanted output and display fluctuations. Rapidly
changing measured values settle with 1% accuracy after this set time
(exponential function damping).

P22: - -- a Dome top tank compensation
FACTORY DEFAULT: 0
a
Compensation
Note
0
OFF
If the EasyTREK is not mounted in the center of the top and the top is flat.
1
ON
If the EasyTREK is mounted in the center of a tank with a dome-shaped top.
It reduces the interference of multiple echoes.

P24: - - - a Target tracking speed
FACTORY DEFAULT: 0
a
Tracking speed
Note
0
Standard
For most applications.
1
Fast
For fast-changing levels.
2
Special
Only for special applications, measuring range is reduced to 50% of the nominal value!
The measuring window is inactive (see
P25
) and the EasyTREK will respond instantly to any target.
In this parameter, evaluation can be sped up at the expense of the accuracy.
