Drain
For specific instructions on draining butanol, refer to the section
“
Draining Butanol from the Butanol Reservoir” in Chapter 8.
During draining, the Auto-Fill mode and the high vacuum pump
operation are automatically turned off. When draining is stopped,
the pump restarts but the Auto-Fill must be turned on again by
selecting this option from the User Settings menu. Whenever the
instrument is turned on, the Auto-Fill is activated. Refer to the
previous caution note.
Graph Options
Refer to Figure 4-2 depicting the graph while reading this section.
