Two-point Calibration Settings
Make two-point calibration settings as explained below.
Setting Range
Two-point calibration requires two types of master workpieces that are different to each
other in size. If the master workpieces are target 1 (T1) and target 2 (T2) respectively,
make settings so that the following conditions will be satisfied.
T1-A < T2-A
Furthermore, set the calibration span between 0.5 and 2.0.
Note: In the case of two-point calibration, the number of averaging measurements is
fixed at 4,096 times.
Press the [ENT] key when the cursor is at 2-TARGET.
1
Place the small master workpiece (T1-A) in the beam.
2
While the cursor is at T1-B, press the [ENT] key. Monitor the measured value
and input the T1-B value.
The display “*********” changes to “+00.00000.”
The cursor moves to the “+” position and to the value can be input.
(1) Press the [Up or Down] key and
select + or – as desired.
