Within two hours of selecting the “Age” function,
m.
the PAV temperature will recover the temperature
lost while loading the samples. When the
temperature recovers to within 0.3° C of the
setpoint temperature, an approximate 20-minute
delay will begin. This is built into the software
to allow the chamber temperature to stabilize.
Following this, the PAV will begin to pressurize.
The timer on the Aging Heat Up screen will display
the total time from when the “Age” button was
pressed until the PAV starts to pressurize. When
the PAV has pressurized to slightly above 2.00
MPa, the aging cycle will automatically begin. The
screen shown at this time will resemble the “Aging
Pressurized” screen.
If the PAV does not reach the setpoint and
i.
pressurize within the two-hour time frame
or has difficulty returning to the setpoint
after pressurizing, check that the power
to the PAV is 230-240 volts. 230 volts
electricity is the minimum required for the
PAV to operate correctly.
If the power supply is 230-240 volts and
the temperature has not recovered,
verify the following:
Be sure that the vessel
a.
lid remains open when
loading sample pans into
the sample holder.
Verify that the samples are
b.
not being heated above
the PAV setpoint prior to
inserting them into the
PAV.
