Functional test process:
1.
Enter four times for the three sections of the functional test.
2.
Click on the "Start Time1" button. Then the functional test is run according to
the four times. Times that have already elapsed are highlighted green. Blinking
green times indicate the functional test progress.
3.
Alternatively, you can press the "Start now" button. Time 1 is set to the current
time and the test starts immediately with the run-up time. Run-up, after-run and
test times proceed according to the specifications. The time progress is also
displayed here in green and blinking green.
4.
If the testing is finished, the 4 time fields are highlighted yellow.
5.
The result can be read in the green highlighted table to the right. You can
switch back and forth between the tables for run-up, test and after-run with
"Change".
Alternatively, the times for test time, run-up and after-run, as well as a delay time
can be entered. The results of the functional test are also saved in archive groups
17 to 20.

In order to receive logical values with appropriate resolution, an adequate test time
must be provided. A few minutes are sufficient for the volume detection via the HF
inputs, because synchronization of the test function with the recording of the vol-
ume frequency takes place. For "slow" inputs, such as interfaces with ENCO or ul-
trasonic gas meters, the test time must be sufficiently long to minimize resolution
