Turning On the Pycnometer
To turn on the pycnometer, place the power ON/OFF switch on the rear
panel in the ON ( | ) position. The system is automatically vented and the fol-
lowing prompt is displayed:
Reload is displayed on the first line, indicating that the system is idle. The
current pressure and current temperature are shown alternately on the second
line. There may be messages containing the results of a previous analysis or
the status of the pycnometer. If there are any error messages, an asterisk ap-
pears in the right corner of the first line. When this occurs, press
to
display the first message. Continue pressing to cycle through all mes-
sages and return to the Reload prompt.
When the system is turned on the first time or after a period of non-use,
it should be allowed to warm up for at least 30 minutes before analyses
are performed. For analyses that require very precise results, it should
warm up for two hours.
It is important that a constant temperature be maintained inside the unit
because a change in temperature could alter analysis results. We recom-
mend that the pycnometer remain turned on at all times to maintain
thermal stability. Power consumption is small and the cost of electricity
will be minimal.
