Remote Communication Error
Purpose:
Indicates an error in setting up a remote data push. This can be
initiated by any failure in the communication set-up.
Category:
Communication errors
Reset:
The error is cleared automatically if the communication is suc-
cessful again.

Measuring Times for Meter Testing
For technical reasons, short measuring times result in higher measuring
deviations. Therefore, it is recommended to use long measuring times to
obtain the desired accuracy.
The following tables show the minimal test times needed to achieve the
stated uncertainty. The values do not include any uncertainty due to tem-
perature variation.
Test conditions: nominal voltage 230V.
