Effect of mA Output Direction on an mA Output
mA Output Direction affects how the transmitter reports flow values via an mA Output. An mA Output is
affected by mA Output Direction only if mA Output Source is set to a flow variable.
The effect of mA Output Direction depends on the setting of Lower Range Value (LRV).
• If Lower Range Value = 0, see Figure 8-1.
• If Lower Range Value > 0, see Figure 8-1 and adapt the chart.
• If Lower Range Value < 0, see Figure 8-2.
