Analog Scaling (option)
Will not display if model does not include analog output.
The display (briefly) shows ANALOG followed by the currently programmed Analog Scaling value. This
scaling variable is used to set the maximum output of 20 mA to a corresponding rate value, which
produces an output ranging from 4 mA for a zero value to 20 mA for the programmed flow rate. The
default initial value is 50.000 (Hz by default K‐factor). Enter the variable directly in the engineering units
dictated by the K‐factor and Rate Time Base.
Example:
 K‐factor entered in pulses per gallon
 Time base programmed for 60 Sec
 Enter 20.000 for 20mA = 20 GPM
When editing the Analog Scaling variable, the leftmost digit will blink (cursor). Use SEL to move the
cursor to the right; the cursor wraps around. Use UP/DN to increment or decrement numerals. Edit the
decimal point last. Use DN to move the decimal point to the right, UP to move it to the left. When the
value displays, use ENT to store the value, exit programming, and return to the RATE display.
