“Digital communications” refers to any method that uses Modbus or HART
communications to interact with the transmitter. This includes ProLink II, ProLink III,
the Field Communicator, and any host.
4. If required for your installation, configure your transmitters for two frequency
outputs and set them to operate in Quadrature mode.
a. Choose Device Tools > Configuration > I/O > Channels.
b. For Channel B, set Channel Type to Frequency Output and click Apply.
c. For Channel C, set Channel Type to Frequency Output and click Apply.
d. Choose Device Tools > Configuration > I/O > Outputs > Frequency Output Mode and select
Quadrature.
5. If required for your installation, choose Device Tools > Configuration > Transmitter Display >
Display Security, then enable and configure a password for the alarm menu.
Security for the alarm menu is required under German law for PTB-type approval for
gas applications.
6. If required for your installation, choose Device Tools > Device Information, then read and
record the firmware checksum values for the transmitter and the core processor.
The checksum values for the transmitter firmware and the core processor firmware
must be read during meter commissioning to meet Weights & Measures
requirements for gas applications in Germany. They may also be useful for
MID/Welmec 7.2 test reports.
7. If required for your installation, monitor the zero value of your system:
a. Choose Device Tools > Configuration > Transmitter Display > Display Variables and
configure Field Verification Zero (FVZ) as a display variable.
b. At the transmitter display, read and record the current value of FVZ.
FVZ is a diagnostic variable that monitors the zero value over a period of 3 minutes.
It must be read during meter commissioning to comply with MID requirements for
Weights & Measures applications in Measuring Instrument Directive (MID) 2004/22/
EC. Refer to your Standard Operating Procedures documentation for detailed
instructions.
8. Enable software security: Device Tools > Configuration > Weights & Measures > Software
Security.
Important
Depending on local requirements, this step may need to be witnessed by a certified Weights
& Measures inspector.
After this step, the transmitter is in a condition of metrological security
(measurement security). The transmitter performs the following actions:
• Securing all measurement parameters. You can read the current configurations
but you cannot change them.
• Clearing Status Alarm A027: Security Breach.
