Weigh the Assembled Penetrometer with Sample

To avoid transferring skin oils, it is recommended to wear latex gloves when handling penetrometers. Skin oils may affect results.

Weigh the assembled penetrometer with sample using an analytical balance. Do not include the spacer when weighing.
Record the mass on the Sample Data Worksheet as Sample + Penetrometer mass.
Subtract Sample mass from Sample + Penetrometer mass. Record on the Sample Data Worksheet as Penetrometer mass.

The mass of the penetrometer must be determined by this method in order to account for the mass of the sealing grease, which varies with each application.
