11.7 Recommended Replacement Perods 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
replacement parts may change to accommodate preventive maintenance over extended
time. Be sure to check with your nearest YOKOGAWA dealer.
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.
