10.1 Operate the transmitter when the Weights &
Measures application is installed
When the Weights & Measures application is installed, many of the basic functions of the
transmitter are modified.
• To make a connection:
- If the physical seal is not installed, you can use any supported connection type.
- If the physical seal is installed, you cannot make a service port connection. You
can use any other supported connection type.
• To read or obtain process data:
- For an approved measurement, you must use an approved method.
- If the measurement does not have to be approved, you can use any available
method.
Important
The behavior of transmitter outputs and process variable values is modified by the Weights &
Measures application. Ensure that you know the effects of this application on outputs and
process variable values.
• To reset totalizers:
- If the transmitter is unsecured, you can reset totalizers. If you reset one totalizer,
all other totalizers are reset automatically.
- If the transmitter is secured, you may or may not be able to reset totalizers,
depending on configuration. If totalizer reset is enabled, you cannot reset
totalizers unless the flow rate is 0. To reset totalizers from the display, you may
need to enter the alarm menu password, whether or not you have enabled it. The
default value for Alarm Menu Password is 1234.
