Enter the volume of the calibration standard to be used in the
calibration (located on the outside of the calibration standards case).
Some pycnometers require and are shipped with multiple standards.
In this instance, the value recorded on the case is the sum for all
standards and is the one that should be entered at the prompt. Press
ENTER.
The range is 0.1 to 999.0000 cm
Press ENTER to begin the calibration or Alt + CLEAR to cancel. The
volume offset is calibrated first (Cal1). When the first calibration is com-
plete, the pycnometer beeps three times and the next prompt is dis-
played.
Place the calibration standard in the cup in the sample cell chamber
and replace the chamber cap. Press ENTER to calibrate the
temperature offset (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
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.
