Determine IN!1 and IN!2 Input Range and Resolution. For our transducer select
0 ~ 100 mV range and LOW resolution (10 µV)
IN!1
= 0 (mV) X 100 (cts/mV) x 1.0 = 0
IN!2
= 30 (mV) X 100 (cts/mV) x 1.0 = 3000
2. Determine correct values for Display Reading
(
RD!1
and
RD!2
)
. In most
cases,
RD!1
and
RD!2
are equal to the minimum and the maximum of the
transducer output range.
RD!1
= 0000
RD!2
= 100.0
3. Scaling the controller.

This scaling method based on 2 input values entered with 2
corresponding reading. Up to 10 linearization points can be
selected to customize the transducer curve. To select
linearization points see “L.PNt” Submenu.
