• Lower Range Value = −x
• Upper Range Value = x
Example: mA Output Direction = Normal and Lower Range Value = 0
Configuration:
• mA Output Direction = Normal (default)
• Lower Range Value = 0 g/sec
• Upper Range Value = 100 g/sec
Result:
• Under conditions of reverse flow or zero flow, an mA Output is 4 mA.
• Under conditions of forward flow, up to a flow rate of 100 g/sec, an 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, an 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.
