DE 

—

Represents –100 % to +100 % of the selected PV span in 
engineering units. FOR EXAMPLE: 
 

Type “T” Thermocouple 

 

 

PV range =  –300 °F to +700 °F 

 

 

PV span =  1000 °F 

 

 

Deviation range =  –1000 °F to +1000 °F

 

 

If PV =  500 °F 

 

 

and SP =  650 °F 

 

 

then Deviation Display =  –150 °F 

 

 

Auxiliary Output =  42.5 % 

NOTE: A deviation of 0°F yields an auxiliary output of 
50 %. 

Low Scale Value within the 
range of the selected variable 
to represent 4 mA 

 

—Use a 

value in engineering units for all selections above except 
Output. 

Use value in percent (%) for Output. (Output can be 
between –5 % and +105 %.) 

 

High Scale Value within the 
range of the selected variable 
to represent 20 mA 

 

—Use a 

value in engineering units for all selections above except 
Output. 

Use a value in percent (%) for Output. (Output can be 
between –5 % and +105 %.) 

*When Deviation is selected, only one operating 
parameter will be entered. This value represents the 
deviation level that will produce 20 mA output. Zero 
deviation will produce a center scale (12 mA) output. A 
negative deviation equal in magnitude to the Auxiliary 
Output High Value will provide a low end (4 mA) output.
