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). ➪
