March 2019
Set mA Output Cutoff in the measurement units used for the process variable. If you change the
measurement unit, mA Output Cutoff is adjusted automatically.
• Default: 0
• Range: 0 or any positive value
Tip
For most applications the default value of mA Output Cutoff should be used. Contact customer service
before changing mA Output Cutoff.

Interaction between mA Output Cutoff and process variable cutoffs

When mA Output Process Variable is set to a flow variable (for example, mass flow rate or volume flow rate),
mA Output Cutoff interacts with Mass Flow Cutoff or Volume Flow Cutoff. The transmitter puts the cutoff
into effect at the highest flow rate at which a cutoff is applicable.
Cutoff interaction
Configuration:
• mA Output Source = Mass Flow Rate
• Frequency Output Source = Mass Flow Rate
mA Output Cutoff = 10 g/sec
•
• Mass Flow Cutoff = 15 g/sec
Result: If the mass flow rate drops below 15 g/sec, all outputs representing mass flow will report zero flow.
Cutoff interaction
Configuration:
• mA Output Source = Mass Flow Rate
• Frequency Output Source = Mass Flow Rate
mA Output Cutoff = 15 g/sec
•
• Mass Flow Cutoff = 10 g/sec
Result:
• If the mass flow rate drops below 15 g/sec but not below 10 g/sec:
— The mA Output will report zero flow.
— The Frequency Output will report the actual flow rate.
• If the mass flow rate drops below 10 g/sec, both outputs will report zero flow.
