11.7 Recommended Replacement Periods for Worn
Parts
To preserve the reliability of the recorder and to use the recorder in good condition for an
extended time, it is recommended that periodic replacements be made on parts.
The table below shows the recommended replacement period for expendable parts.
The replacement period shown here applies when the recorder is used under standard
operating conditions. For the actual replacement period, consider the actual conditions
of use.
Replacement of parts other than the chart paper, pen, ribbon cassette, and internal light
LED will be carried out by a YOKOGAWA engineer or an engineer certified by
YOKOGAWA. Contact your nearest YOKOGAWA dealer when such replacement is
necessary.
Note
The replacement period of the display and the internal light LED is the half life of the
brightness. The deterioration of brightness varies depending on the condition of use, and its
determination is subjective. Consider these facts for determining the actual replacement
period.
