Analog output scaling
When entering the Analog programming menu, the first screen asks to select the Analog Source, or what
the analog output value is to represent. There are 4 choices as shown in Figure 23.
Using the
UP
and
DN
buttons scrolls through the 4 choices that the mA output can represent: a fixed mA
output value, the input flow rate, the totalizer value or the grand totalizer value. Press
ENT
when
correct choice is showing.
Fixed output source
This option allows the user to select a constant mA value the RT-30EX will output regardless of any
changing values. A constant mA signal could be used as an external indicator showing if the RT-30EX is
on. Allowable values are from 2mA to 20mA.
