Calibrating Inserts
An insert must be calibrated and its operation verified since it essentially becomes a different
size sample chamber. Appropriate calibration standards are included in the MultiVolume kits.
For example, if you have a 100-cm
3
capacity AccuPyc and plan to use a 10-cm
3
insert, then
you must calibrate the sample chamber with the 10-cm
3
insert, cup, and calibration standards.
1-, 10-, 3.5-, 35-, 650-, and 1300-cm
3
Inserts
These inserts are calibrated in the same manner as the sample chamber itself.
1. Remove the sample chamber cap.
2. Place the insert and sample cup into the sample chamber; replace the chamber cap.
3. Calibrate the insert following the steps in Calibrating the Pycnometer in Chapter 2.
4. Verify operation following the steps in Verifying Operation in Chapter 2.
0.1-cm
3
Insert
Because of the size of the 0.1-cm
3
insert, its calibration is performed in a different manner
from that of other inserts.
1. Remove the sample chamber cap.
2. Place the insert into the sample chamber (the sample cup is built into the insert); replace
the chamber cap.
3. Press
Alt + 4
to access the Analyze function.
Press ENTER until the Chamber Insert prompt is displayed;
Ensure that None is displayed.
4. Press
ENTER;
the Analyze prompt is displayed. Press
ENTER
again to begin the
calibration.
5. After the calibration is complete, the Reload prompt is displayed.
If your 1-cm
3
pycnometer has not been calibrated recently, you should perform a
calibration before calibrating the 0.1-cm
3
insert.
