The IG Series include main units (IG-1000, IG-1500) and expansion units (IG-1050, IG-
1550). By connecting the expansion unit to the main unit, the IG Series can be used for
various purposes.
Calculation function
Tolerance is judged based on the calculated result (calculated value) of measurement value
of two units of IG Series and the analog output can be performed.

„ Adding the measurement value
The diameter or width of a target that
cannot be measured with one unit can be
measured.
„ Subtracting the measurement value
The level of a target can be calculated.
Interference prevention function
Mutual interference can be prevented between the additionally installed IG Series units.
