6. Create the following program to scale values in a range between the lower
and upper-limit values and designate the lower- and upper-limit values that
have been monitored as parameters. Refer to page 89, Scaling for details.

If the Analog Input Unit is set to a range of –10 to 10 V, follow the steps described
below to adjust the Analog Input Unit.

1. Refer to 3-1 Settings and connect the Analog Input Unit, CPU, and sensor or
transducer.
2. Connect a peripheral device such as a Programming Console to the CPU
and while referring to 3-3-1 Programming, create a program to convert 2’s
complement.

3. Obtain the minimum value of the sensing object. For a sensing operation, for
example, set the sensing object so that the output value of the sensor or
transducer will be minimum. For temperature measurement, it may be diffi-
cult to obtain the minimum value. In that case, instead of using the sensor or
transducer, use a reference power supply to obtain the output at the lowest
temperature.
