10.10 Check Frequency Output Scaling Method

If Frequency Output Scaling Method is set incorrectly, the Frequency Output may report an incorrect value.
Procedure
1. Verify the configuration of the Frequency Output.
2. If you changed the setting of Frequency Output Scaling Method, check the settings of all other
Frequency Output parameters.

10.11 Check grounding

The sensor and the transmitter must be grounded.
Prerequisites
You will need an:
• Installation manual for your sensor
• Installation manual for your transmitter (remote-mount installations only)
Procedure
Refer to the sensor and transmitter installation manuals for grounding requirements and instructions.

10.12 Check HART Address and mA Output Action

If the transmitter is producing a fixed current from the mA Output, the mA Output Action parameter may be
set incorrectly.
When the mA Output Action parameter is set to Fixed, the mA Output produces a fixed value, and does not
report process data or implement its fault action.
When HART Address is changed, some configuration tools will automatically change mA Output Action.
Tip
Always verify mA Output Action after setting or changing HART Address.
Procedure
1. Set HART Address as appropriate for your HART network.
The default address is 0. This is the recommended value unless the transmitter is in a multidrop
network.
2. Set mA Output Action to Live.

10.13 Check HART burst mode

HART burst mode is normally disabled, and should be enabled only if a HART Triloop is being used.
Procedure
1. Check to see if burst mode is enabled or disabled.
