11.5 Adjusting the Pen Position (Pen Model)
This section explains the details of adjusting the pen position on the chart paper.
It is recommended that the pen be adjusted once a year to assure its recording accuracy.

Pen position is adjusted under standard operating conditions when the recorder is shipped from
the factory. Because the chart paper may expand or contract depending on the environment in
which the recorder is used, it is recommended that the position be readjusted before use.
