Troubleshooting - Konica Minolta CM-23d Instruction Manual

Troubleshooting

If an abnormality has occurred with the instrument, take the necessary actions as given in the table below. If the
instrument still does not work properly, turn the power OFF and temporarily disconnect the battery. Reinsert the
battery and turn the power back ON. If the symptom remains, contact a KONICA MINOLTA-authorized service
facility.
Symptom
The instrument does not
start up even though the
power is ON, or it turns
off immediately.
Measurement cannot be
performed even by
pressing the
measurement button.
Measurement results are
abnormal.
Measurement results
fluctuate.

Check Point
Has the battery been inserted
correctly?
Is the battery dead?
Is measurement still in
progress?
Is a screen where
measurement is possible
displayed?
Is the viewfinder open?
Is the specimen placed
properly?
Is there any foreign material on
the surface of the target mask
or around the specimen
measuring surface?
Are there marks on the surface
of the target mask around the
specimen measuring port?
Is there foreign matter or other
dirt adhering to the inside of
the integrating sphere?
Is proper calibration data
used?
Was white calibration
performed correctly?
Was zero calibration
performed correctly?
Is the instrument and
specimen kept stationary
during measurement?
Action
Insert the battery correctly, or use the AC adapter or
USB bus power to charge the battery.
Wait until the beep indicates that measurement is
complete, or verify that the LCD has changed before
performing the operation.
No beep can be heard.P.105 "Beep", and check the
beep settings.
The measurement button must be pressed while a
screen that allows measurement (e.g. Calibration,
Target, or Sample screen) is shown.
Use the viewfinder lever to securely close the viewfinder.
If the inside of the integrating sphere is illuminated and
shining, the viewfinder lever is not closed.
Remove any foreign matter, etc. caught in the viewfinder
lever components.
The measurement results may be affected if
measurement light leaks. Set the instrument so that the
sample is as close to the target mask surface as possible.
Measurement results may be affected if foreign matter
becomes caught between the specimen and the target
mask surface. Clean the specimen surface or the target
mask measurement surface according to the specified
method.
If the sample and the target mask surface are not in
contact due to a dent or the like, the measurement results
may be affected. To replace the target mask, please
contact a KONICA MINOLTA-authorized service facility.
Foreign matter or dirt larger than several mm may
affect the measurement results. Foreign matter and
dust inside the integrating sphere can easily scratch
the barium sulfate paint on the inside of the sphere.
Use a blower to blow off those objects. If such objects
cannot be removed with the blower, zero calibration
and white calibration may improve performance.
Calibration data is written to the unit using the white
calibration data writing software included with the
calibration table. Execute white calibration using the
correct calibration plate corresponding to the written
calibration data.
P.36Read "White Calibration" to perform white
calibration properly.
P.34 "Zero calibration" and perform zero calibration
properly.
Do not allow the instrument and specimen to move
during measurement. Use averaging measurement as
needed.
