For example, when setting the X1 value as an input value of the smallest object,
execute a scaling command while the smallest object is being sampled. In the
same manner, the X2 value can be set as the largest object input value if the
scaling command is executed while the largest object is being sampled.
Actual size
By using the set value teach command, an actual input value can be set as the
HH, H, L, or LL set value. It is useful for making judgments on whether products
are acceptable or defective.
For example, when setting the lowest set value LL, execute the set value teach
command while the smallest object is being measured. If the same command is
executed while the largest object is being measured, the highest set value HH
can be set.
Actual size
The forced zero function enables the Unit to shift the scaled conversion data to 0
to calibrate, which allows relative object measurement with ease.
The forced zero state stays in effect until ZERO RESET input signal to the Unit is
turned ON.
When zero input is turned ON while the Unit is sampling data, the scaled conver-
sion data will be shifted to zero and stored as binary data in the input word, or the
comparison result flags of the input word are turned ON or OFF according to the
comparison result processed by the Unit.
