General notes for operation

The BTU meter can be configured using keys or using the "FieldCare" operating software.
The operating software, including the interface cable, is available as an order option, i.e. it is not
part of the basic scope of delivery.
The configuration is locked if the device is locked by the custody transfer switch, user code or
digital input. For devices locked by custody switch, custody transfer-related parameters can be
changed only up to three times. Afterwards, no more access to these parameters is possible. (For
details, refer to the section on "Access protection" in the Operating Instructions on CD-ROM)
