7.8 Test output
The internally located test output is intended for testing laboratories.
The manufacturer supplies two special cables:
1. Volume testing pulses
2. Energy testing pulses
Please refer to the inspection and testing manual for further specifications
(pulse weighting, pulse duration/pause, pulse frequency).
Ensure that the temperature sensors (measurement resistances)
remain in contact without interruption during energy verification.

Display
The data generated by the calculator can be viewed in several displays.
These displays contain the assigned system information (e.g. energy
quantities, water volumes, operating days, water quantities, actual tem-
peratures, maximum values) and can be accessed by calling the displays
in the pre-defined sequence / loop. The energy meter has up to 6 differ-
ent display sequences / loops.
Main loop, due date loop, information loop, pulse input loop, tariff loop.
The month loop comprises up to seven readings alternatingly displayed
for 2 s - 4 s each. For quick visual identification, the loops are labelled
1 to 6 in the display. As standard, the main loop contains the actual
data, e.g. energy, volume, flow and temperatures. The verified register is
marked with a padlock icon.
