The table below lists the error messages and their remedies.
LASER EMISSION
Display Meaning Remedies
Segment error
There is no measuring object that
corresponds to the specified segment.
Shutter is closed.
Laser dose not come into reception unit.
Laser characteristic may be deteriorated.
Check if a workpiece is present.
Check the segment settings.
Open the shutter.
Check the LASER EMISSION LED.
Setup item error
There is a certain conflict in the setup data.
Press the key to clear the error message.
Previously setup contents are lost. Redo setup from the
beginning.
Calibration error
Incorrect segment setting
A value significantly different from the dimension of
the reference gage is entered.
The HIGH CAL setting value is too close to
the LOW CAL setting value.
Press the key to clear the error message.
Redo the segment setting again.
Cancel the setting value, then set it again.
For information about the cancellation procedure,
refer to Section 4.2, "Calibration".
Setup value error:
The upper limit value is set lower than the lower
limit value, or HIGH CAL LOW CAL.
Input the unacceptable value.
Signal cable is not connected.
Incorrect measuring unit is connected.
Clear the error message by pressing the key.
Clear the wrong setup values and re-enter the correct
values.
Inconsistent ID unit serial data
Serial numbers are not consistent between the ID unit
and Measuring Unit.
The ID unit has a unique number for each Measuring
Unit. Always mount the ID unit that has the same serial
number as the Measuring Unit to be used.
Turn off the power and mount a correct ID unit.
Laser does not scan.
Signal cable is not connected.
Short-circuiting pin is not inserted in the remote
interlock connector.
Laser diode is deteriorated.
Scanner motor is not running.
Turn off the power and connect the signal cable.
Insert the short-circuiting pin.
Contact the nearest dealer or Mitutoyo sales
representative.
Turn off the power and connect the signal cable.
Connect the Display Unit to the appropriate Measuring
Unit.
Laser diode anomaly
(LASER EMISSION LED is flashing.)
The laser diode is forced to operate below
a temperature outside the specified range.
Laser diode begins to deteriorate.
Using the laser diode at a high temperature reduces
efficiency and accelerates deterioration in addition to
drawing a large current. Take appropriate measures to
cool the diode.
Contact the nearest dealer or Mitutoyo sales
representative.
The dummy ID unit is installed.
Internal circuit error.
Replace the dummy ID unit with the ID unit supplied
with the measuring unit.
Contact the nearest dealer or Mitutoyo sales
representative.
