7.2 Error Messages and Remedies
The table below lists the error messages and their remedies.
LD 1 ON LD 2 ON
Display Meaning Remedies
Segment error
• There is no measuring object that
corresponds to the specified segment.
• Shutter is closed.
• Laser does not come into reception unit.
• Laser characteristic may be deteriorated.
• Check if a workpiece is present.
• Check the segment settings.
• Make sure that the connection cable is connected
between the Emission Unit and Reception Unit.
• Open the shutter.
• Be sure to align the optical axis correctly, if the Emission
Unit and Reception Unit are separated from the mount.
For details, refer to the measuring unit user’s manual.
• Check the LD ON 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 4.1, "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.
• 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.
Laser diode anomaly
(LD ON 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.
• Signal cable is not connected.
• Incorrect measuring unit is connected.
• Turn the off power and connect the signal cable.
• Connect the Display Unit to the appropriate Measuring
Unit.

Printer error
• Cable is not connected or broken.
• Communication conditions are not consistent.
• Check the cable connection.
Setup value error:
• Cable is not connected or broken.
• Check the cable connection.
¥ When the printer is not used, set to in the basic
¥ setup.
Stained protection glass has been detected.
(In the case where the stained protection glass detection
function has been set.)
Abnormal power supply
• Low line voltage
•
Power supply is adversely affected by a surge current, etc.
• Turn on the power again.
• If this indication is repeated, check the line voltage for
any abnormality such as a level drop and/or interference
noise.
• Clear the message by pressing the key.
• Clean the protection glass, referring to the measuring unit
¥ user’s manual.
