TRANSMITTER CHARACTERIZATION — This
selection lets you instruct the recorder to characterize a
linear input to represent a nonlinear one.
NOTE: Prompt only appears when a linear actuation
is selected at prompt ‘IN1 TYPE”.
FOR EXAMPLE: If input 1 is a 4 to 20 mA signal, but
the signal represents a type "K" thermocouple; select
"K TC H" and the recorder will characterize the 4 to
20 mA signal so that it is treated as a type "K"
thermocouple input (high range).

in engineering units
INPUT HIGH RANGE VALUE in engineering units is
displayed for all inputs but can only be configured for
linear or square root transmitter characterization.
Otherwise, this is a read-only display of the higher range
value for the selected T/C or RTD input including
transmitter characterization, if applicable.
Scale the #1 input signal to the display value you
want for 100%.
EXAMPLE:
Actuation (Input) = 4 to 20 mA
Process Variable = Flow
Range of Flow = 0 to 250 Gal/Min
High Range display value = 250
Then 20 mA = 250 Gal/Min
The control setpoint will be limited by the range of units
selected here.
