Emerson Micro Motion 1600 - 8.4.4 Configure mA Output Cutoff

Example: mA Output Direction = Normal and Lower Range Value < 0
Configuration:
• mA Output Direction = Normal
• Lower Range Value = −100 g/sec
• Upper Range Value = +100 g/sec
Result:
• Under conditions of zero flow, an mA Output is 12 mA.
• Under conditions of forward flow, for flow rates between 0 and +100 g/sec, an mA Output varies between
12 mA and 20 mA in proportion to (the absolute value of) the flow rate.
• Under conditions of forward flow, if (the absolute value of) the flow rate equals or exceeds 100 g/sec, an
mA Output is proportional to the flow rate up to 20.5 mA, and will be level at 20.5 mA at higher flow rates.
• Under conditions of reverse flow, for flow rates between 0 and −100 g/sec, an mA Output varies between
4 mA and 12 mA in inverse proportion to the absolute value of the flow rate.
• Under conditions of reverse flow, if the absolute value of the flow rate equals or exceeds 100 g/sec, an
mA Output is inversely proportional to the flow rate down to 3.8 mA, and will be level at 3.8 mA at higher
absolute values.

Cutoff
mA Output Cutoff specifies the lowest flow rate that will be reported through an mA Output. All flow rates
below the specified value are reported as 0.
mA Output Cutoff is applicable only when mA Output Source is set to a flow rate variable. It is applied to
whatever flow variable is assigned to an mA Output.
Procedure
Set mA Output Cutoff as desired.
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.
