3. To adjust Output Zero Point (4mA) and Output Span Point

(20mA) the unit must be in the functional area as noted below

while adjustment is via

keys. The value shown is a percent-

age of the pressure range (span) as noted on the product label

(ex. If product was supplied as a 0-40 IWC range and the user de-

sired the Output Zero Point (4mA) to be “moved” from 0 IWC to 20

IWC then Output Zero Point would be 50.0 which is 50%.

C. Re-scaling in “Arbitrary” units, “Linear Display Mode.” This function

allows the user to establish a linear relationship from the standard “inH

O”

unit to any user defined unit.

Note: See menu schematic on last page. Unit must be in “Linear Display

Mode” option within “Setting Mode”, this is noted on the screen by

Use

keys to move between “Linear Display Mode” and “Pressure

Display Mode.”
