■ Main Functions
Measurement
Input Calculation
• Two input circuits are provided. The input ranges for these circuits
can be set independently. For example, one can be set to 4 to 20
mA and the other can be set to 1 to 5 V.
• In addition to calculations such as K (constant)–A (input for one cir-
cuit), it is possible to perform calculations based on the inputs for
both circuits, such as A+B and A–B, making it possible to perform
thickness measurement and level-difference measurement using
displacement and length-measuring sensors.
Timing Hold
Normal
• Continuously performs measurement and always outputs based on
comparative results.

Scaling
Scaling converts input signals in any way required before displaying
them. The values can be manipulated by shifting, inverting, or +/–
reversing.

Teaching
Settings for scaling can be made using the present measurement
values instead of inputting values with the SHIFT and UP Keys. This
is a convenient function for making the settings while monitoring the
operating status.

Average Processing
Turns the comparative output OFF until the measurement value
enters the PASS range.
Average processing of input signals with extreme changes or noise
smooths out the display and makes control stable.
Previous Average Value Comparison
Slight changes can be removed from input signals to detect only
extreme changes.

Temperature Input Shift
Shifts the temperature input value.
