IL Series-IM_E
There are two types of tolerance setting values: HIGH (upper limit) and LOW (lower
limit). The value displayed will output its signal as one of the following 3 levels: When
the value exceeds the upper limit (HIGH); when the value is within the tolerance
range (GO); and when the value falls below the lower limit (LOW).
"5. Output method" (Page 10)
Manual setting
Set the HIGH tolerance value (upper limit) and LOW tolerance value (lower limit) to
an arbitrary value.
1 Press the / button several times on the
basic display. Then display the HIGH tolerance
value on the sub display (lower level).
2 Press / button to set the HIGH tolerance value.

4 Press the / button to set the LOW side
setting value.

The tolerance settings are complete.
Automatic setting (When other than step count filter)
Tolerance tuning
When a reference workpiece (master workpiece) is available, set the measured
value of the master workpiece. The HIGH tolerance value (upper limit) and LOW
tolerance value (lower limit) will be automatically set symmetrically with respect
to the measured value of the master workpiece.
2-point tuning
If there are an acceptable target and a HIGH or LOW defective target, these
two targets can be registered. As a result, the middle value between the
acceptable and the HIGH or LOW defective is set as the tolerance value.
For details of tolerance tuning and 2 point tuning, refer to the User's Manual.
Automatic setting (when step count filter)
2 point tuning
When there is a standard step, 2 times the value of the step will be set as HIGH
(upper limit value) and half of the value of the step will be set as LOW (lower
limit value) automatically.
If the step of the measured value of the upper part is A, and the measured part
of the lower part of the step is B, it will be set as
HIGH = <(A-B) x 2>, LOW = <(A-B)÷2>
1 point tuning
Based on the presently displayed P.V. value, 2 times the value of the P.V. value
will be set as HIGH (upper limit value), and half of the value of the P.V. value will
be set as LOW (lower limit value). If the P.V. value is A, it will be set as
HIGH = <(A) x 2>, LOW = <(A) ÷ 2>
For details of 2 point tuning and 1 point tuning, refer to the User's Manual.
When the [ZERO SHIFT] button is pressed or the external zero shift input* has been
activated, the R.V. (internal measurement value) now becomes the newly shifted
target value.
*Zero shift via external input is provided by assigning zero shift input to the external
input 1 (pink wire).
Setting the shift target value
1 Use the / button on the basic display to
display the shift target value on the sub display
(lower level).
2 Press the / button to change the shift target
value.
IL-030/IL-065/IL-100

The shift target value has now been set.
Activating the zero shift
Press the [ZERO SHIFT] button or assign zero shift input to an external input.
The zero shift indicator [ZERO SHIFT] will light up for approx. 0.5 second and the
current R.V. (internal measurement value) will now become the shifted target value.
Cancelling the zero shift
Press the zero shift button [ZERO SHIFT] for 2 seconds or more.
The main display shows [] while the sub display shows [], indicating that
the zero shift has been cancelled and set back to the factory setting.

When setting the tolerance value manually or with the 2-point
tuning, make sure to set "HIGH tolerance value > LOW tolerance
value".
The tolerance tuning cannot be performed when the P.V. value
(judgment value) is displayed as [].
The 2-point tuning cannot be performed when the R.V. value
(internally measured value) is displayed as [].
When the R.V. value is [], the 2 point tuning cannot
occur. If it does occur, (no.vAL) will be displayed on the main
screen, and the number of points will decrease. The setting
value cannot be changed.
When the P.V. value is [], 1 point tuning cannot occur. If
it does occur, (no.vAL) will be displayed on the main screen,
and the number of points will decrease. The setting value
cannot be changed.

• When using the external zero shift function, any newly shifted
states will be lost when the unit is powered down unless the
memory function is utilized.
For details, refer to the User's Manual.
• When the R.V. value (internal measurement value) is [],
and when (3. AVE) is set to (HPF), the zero-shift function
cannot occur.
