12.5 Recommended Replacement Perods for Worn
Parts
To maintain the reliability of the MV and to use the MV in a good condition for an
extended time, we recommend that parts be replaced periodically. The replacement parts
may change to accommodate preventive maintenance over extended time. Be sure to
check with your nearest YOKOGAWA dealer.
The following table shows the recommended replacement period for expendable parts.
The replacement period shown here applies when the MV is used under standard
operating conditions. For the actual replacement period, consider the actual conditions
of use. Replacement of parts will be carried out by a YOKOGAWA engineer or a
YOKOGAWA-certified engineer. Contact your nearest YOKOGAWA dealer when such
replacement is necessary.

Note
• The LCD replacement period indicates the half life of the brightness when the brightness
is set to the factory default setting. The half life is shortened as the brightness is set
higher. The deterioration of brightness varies depending on the condition of use, and its
determination is subjective. Consider these points when determining the actual replacement
period.
• The LCD color may turn yellowish over time. The discoloration tends to progress faster as
the brightness is set higher.
