7.2 Maintenance procedure
To operate the instrument properly and keep it in favorable operation status, it is essential to perform main-
tenance and inspection periodically.
Note that the Table 7
2 provides the guideline for maintenance items and intervals, assuming standard gas,
operation, and installation environment. When you perform maintenance by yourself, add the items or mod-
ify intervals as required to suit the installation environment.
However, do not extend the maintenance cycle of each maintenance item.
We do not warrant the damage resulting from the use not observing periodical maintenance.
