Main functions
| Function name | Description |
|---|---|
| Measurement
cycle |
Set as needed according to workpiece reflectance, tilt, etc.
You can also use the auto-configuration feature to automatically set the optimal measurement cycle for the workpiece being measured. |
| Average rate | Set as needed according to measurement value stability. |
| Calculation | Enables calculation between multiple sensor heads and amplifier units.
Provides addition and subtraction features, which you can use to measure level difference, thickness, etc. Calculation is performed by the master unit. |
| Analog output | Allows you to change analog output to voltage output and current output. |
| Analog scaling | Function for adjusting analog output against measurement results. Use, for example,
when you want to present slight changes in displacement as large changes in analog output. |
| Measurement
scaling |
Function for applying correction to measurement results.
Use when there is a difference between the expected result and measurement result, or when you want to apply a certain offset value. |
| Detection select | Allows you to select which surface to use for your measurement result, in cases
where multiple measurement surfaces exist within the range of measurement. Use when measuring through glass, or detecting front/back surfaces of thin film. |
| Differential
calculation |
With this function, the measurement result is the difference between the current
displacement amount and that of a given time earlier. Use when counting thin, board-like workpieces or when exclusively detecting sudden changes. |
| Hold function | With this function, the detection result is the feature value for the specified period.
You can select which feature value to extract, e.g., the peak value (peak hold), the bottom value (bottom hold), the range of change (peak-to-peak hold), and so forth. |
| Timer mode | Allows you to delay upon changes in judgment output, or turn PASS output ON for a
given period. Use when the judgment output changes so rapidly that upper-level devices cannot receive the signals. |
| Synchronization | Allows you to specify sensor head measurement timing.
By staggering measurement timing, you can prevent mutual interference between sensors. |
| BANK change | Allows you to save/load sensor settings to the BANK.
This function lets you change multiple settings (e.g., measurement cycles and threshold values) at once, which is useful in product changeovers, etc. |
