7.2 Cylinder selection
AS-100 Powder density tester is supplied with a 25ml, 50 ml, 100 ml, 250 ml graduated cylinder. In order to improve test accuracy, it is recommended to select the appropriate cylinder based on the measured weight of powder (m) and apparent density (ρ).

Note: It is recommended to select small volume in order to improve the accuracy.
7.3 Cylinder installation
Please install the cylinder as follows:
7.3.1 Place Polyurethane washer from the upper side of the cylinder.
7.3.2 Place screw cap from the upper side of cylinder.
7.3.3 Place silica jel pad on bottom of the cylinder,
7.3.4 Screw down the cap slowly until get fixed.
7.3.5 Place the tapping apparatus into the hole in the guide bearing.
Note: The cylinder is fragile, please handle carefully.
7.4 Amplitude adjustment
The maximum amplitude is 15mm and the default is 3mm (made up of 1 pc 1mm and 1 pc 2mm tapping washer). More tapping washer are available (1mm, 2mm or 5mm).
