• mA Output Direction = Normal
• Lower Range Value = 0 g/sec
• Upper Range Value = 100 g/sec
Result:
• Under conditions of reverse flow or zero flow, the mA Output is 4 mA.
• Under conditions of forward flow, up to a flow rate of 100 g/sec, the mA Output varies between 4 mA and
20 mA in proportion to the flow rate.
• Under conditions of forward flow, if the flow rate equals or exceeds 100 g/sec, the mA Output will be
proportional to the flow rate up to 20.5 mA, and will be level at 20.5 mA at higher flow rates.
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, the mA Output is 12 mA.
• Under conditions of forward flow, for flow rates between 0 and +100 g/sec, the 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, the
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, the 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, the 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.

Flow Rate Cutoff
mA Output Cutoff specifies the lowest flow rate that will be reported through the 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 all
flow rate variables: mass flow rate, liquid volume flow rate, gas standard volume flow rate, and so on.
Procedure
Set mA Output Cutoff as desired.
