2.2 Operating modes, meter states and signal output
The FLOWSIC600 has two operating modes (  pg. 16, 2.2.1):
● Operation
● Configuration Mode
In Operation Mode, the meter can have the following meter states (  pg. 17, 2.2.2):
● Measurement valid
● Chck request
● Data invalid
2.2.1 Operation mode and configuration mode
The meter can be operated by the user in two modes: Operation Mode or Configuration
Mode.
Operation Mode
In Operation Mode, the meter runs in one of the three aforementioned meter states,
depending on the measuring conditions.
Configuration Mode
The Configuration Mode is used to modify parameters that directly influence the measure-
ment and to test the system and output signals. Configuration Mode forces the meter into
the meter status "Data invalid" and the digital output "Measurement valid" is deactivated.
Invalid measured values may be produced. The system continues operation using the
current sample rate and executes all calculations as in the Operation Mode. Frequency
output and analog output may represent test values and do thus not necessarily indicate
measured values. Any parameter modifications are applied immediately to the running
calculations with the following exception: changes of the sample rate or of the configura
-
tion of the serial interface are applied after the meter is switched to Operation Mode.
If the meter is in Configuration Mode and there have been no activities either
on the LCD display or via MEPAFLOW600 CBM for more than 15 minutes, the
meter automatically switches to Operation Mode.
