Example of Operation You are to measure the diameter of round bars. The reference diameter is 10
mm, and you wish to convert a difference of 1 mm into 1 V.
In this case, first set 100.000 mm to 0 V. Then, to represent each 1 mm
change in diameter from the reference by 1 V, set the reference plus 6 mm to
+6 V and the reference minus 6 mm to -6 V. That is, +6 V = 16 mm and -6 V
= 4 mm.
Step Key operation Display
1 Use PRM to display analog
voltage range.
2 Press "1".
3 Press "6".
4 Press ".".
5 Press "0" four times.
6 Press ENT
7 Press "4".
8 Press ".".
9 Press "0" four times.
10 Press ENT.
The LS controller is factory-set to +6 V = 60 mm and -6 V = - 60 mm.
•A range of 0.024 mm to 240 mm can be specified.
Make sure that the value corresponding +6 V is greater than that for -6 V.
When your reference value is an integer with no decimals, steps 4, 5, 8
and 9 can be omitted.

LIMIT
You can set the following 3 parameters in LIMIT:
3-step or 7-step differentiation
Tolerance limits when 7-step differentiation is selected
Comparator output type; Relay or open-collector (if the measured value is
above the upper limit or below the lower limit).
Use FNC to set the tolerance limits for the measured value appearing on
the subdisplay (CH2).
