dEFiNitiONS:
Flat Particles — The particles having a ratio of width to thick-
ness greater than a specified value.

MAiNtENANCE:
Very little maintenance is required for the Four-Station Caliper.
Clean the Caliper before each test to avoid foreign particles
which may effect results. Every six months add a drop of oil
into the ratio holes for smooth operation. Periodically, inspect
parts for wear to ensure compliance with ASTM D4791.
