commissioning
4.1 Default values
Default values for your SGM meter are configured at the factory.
Important
Default values are based on your purchase order options. Therefore, the default values described in the
following tables may not be the factory default values configured for your system. For absolute accuracy,
refer to the configuration sheet that was shipped with your meter.
