12. If You Suspect a Malfunction
The following should be checked if the instrument is not functioning as
expected.
■
The instrument doesn’t work even though the power is ON.
1) Are the correct batteries installed?
-> Use only AA alkaline dry or nickel metal-hydride rechargeable
batteries.
-> Check the polarity/orientation of the batteries.
2) Is one or both of the batteries spent?
-> Replace both batteries (at the same time).
Leakage can occur when using an old and new battery together, and
can result in damage to the instrument.)
3) Is the power cord for the AC adapter (optional) connected correctly?
4) Are you using the dedicated AC adapter that came with the instrument?
-> Never use an AC adapter or power cable other than the dedicated
one available for use with this instrument, as damage can result.
■
Normal measured values are not displayed.
1) Does the instrument’s wavelength setting match the wavelength being
measured?
-> Edit the wavelength setting using the wavelength switching key.
2) Is the optical connector (optical fiber) attached correctly?
-> Check the connections. Insert the SC connector until it locks. For
FC connectors, fasten the attachment ring all the way.
If the connection is not sound, measurements will be inaccurate.
3) Are the ends of the optical connector fibers damaged or dirty?
-> Clean them with a dedicated optical connector cleaner. Using
fibers with damaged ends can result in erroneous measurement.
■
When the instrument starts up, the backlight automatically blinks and
does not stop.
The instrument’s self-diagnostic function has detected an error.
-> Contact the dealer from which you purchased the instrument for
repairs.
Do not attempt to repair the instrument yourself, as doing so can be
very dangerous.
