4-3-4. Scaling
This changes the display dimension magnification. This is mainly used when measuring objects with different
reduced scales or when taking die shrinkage into account for cutting.
Example 1. When measuring a 1/2 model as an equal magnification model
By setting 2.000000, the display changes by 2 mm for each 1 mm of movement.
Example 2. When cutting a die for a resin part with a resin molding shrinkage ratio of
0.95%
A large die is cut in consideration of shrinkage, so the die dimension relative to the part
dimension is 1/0.95. Therefore, a die can be cut with the part dimensions as is by setting
1.052631.
4-3-5. Linear compensation
Unlike gauge-type measuring units, scale-type measuring units experience dimensional error caused by
sagging of the device to which the scale is attached. You can compensate this sagging by measuring the
compensation value as outlined in “2-19-2 Linear compensation” of the Operating Manual, and setting that
value.
4-3-6. Hold function
The hold function consists of a latch function and a pause function.
Latch : You can hold the display even while the measuring unit is moving. This is used to read the dimension
at a particular point without stopping movement during measurement.
Pause : You can pause updating of the peak value calculation even while the measuring unit is moving. Data
resulting from movement while paused is not reflected to the peak value calculation.
4-3-7. General-purpose input
You can perform operations by external contact point input instead of key operations.
Possible operations
• Hold
•
Restart
• Display data switching
• Relocation of datum points using reference points or relocation of master calibration values using reference
points
IN-A Counter display A Hold, restart, display data switching, relocation of datum points and
IN-B Counter display B
master calibration values using reference points
IN-C Counter display C Hold, restart, display data switching
Hold Function ON at first input; function OFF at second input
To enable use
Check the following circuits, then make the necessary wiring connections and input the signal.
