26 Digital Indicators K3HB-X/-V/-H/-S
■ Main Functions
Measurement
• 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.
Normal
• Continuously performs measurement and always outputs based on
comparative results.
Peak Hold/Bottom Hold
• Measures the maximum (or minimum) value in a specified period.
Sampling Hold
• Holds the measurement at the rising edge of the TIMING signal.
Peak-to-peak Hold
• Measures the difference between the maximum and minimum val-
ues in a specified period.
Scaling converts input signals in any way required before displaying
them. The values can be manipulated by shifting, inverting, or +/–
reversing.
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.
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.
Slight changes can be removed from input signals to detect only
extreme changes.
Shifts the temperature input value.
