Insert Cal Std
[ENTER] to start
Place the calibration standard in the cup in the sample cell chamber
and replace the chamber cap. Press ENTER to calibrate the volume
(Cal2). Calibration continues and operational status messages are
continually displayed. After the operation is complete, the pycnometer
returns to the Reload prompt.
For best results, sample volume should be approximately equal to the
volume of the calibration standard. Therefore, if calibrating the 10 cm
3
pycnometer for use with smaller sample volumes, use only one
standard. If using one standard, enter half of the value at the Volume of
cal std prompt. Press Alt + CLEAR to cancel the operation.
RESET PRESSURE CALIBRATION
Contact a Micromeritics Service Representative and schedule a proper pressure cal-
ibration since data accuracy may be compromised.
This option can be used when the pressure is suspected of not being reported correctly by the
analyzer. For example: a zero, negative, or unreasonably high reading is being consistently
reported. Resetting to nominal may restore normal pressure readings but a proper calibration should
be performed.
