Scaling can be used to change the values displayed for the temperature input
values to any values required by the user. Scaling eliminates the need for lad-
der programming in the Master to perform math operations. To scale the tem-
perature input values (i.e., the measured values) to the values required by the
user, conversion values between − 28,000 and 28,000 are set at 2 points (i.e.,
100%, and at 0%) using the Configurator.

(1) The default values are 0 to 28000.
(2) Reverse scaling, where the 0% scaling value is higher than the 100%
scaling value, is also supported.
Offset compensation can be used to compensate for error that occurs during
scaling. The offset amount is added to the scaled line after scaling, as shown
in the following diagram. The offset (error) value can be input between
28,000 to 28,000, but be sure that underflow or overflow does not occur. The
