Plastic Viscosity (PV), cP

= 600 RPM reading - 300 RPM reading

Yield Point (YP), lb./100 ft

2

= 300 RPM reading - Plastic Viscosity (PV)

Apparent Viscosity (AV), cP

= 600 RPM reading / 2

Gel Strength, 10 second, lb./100 ft

2

= the maximum dial deflection after 10 sec.

Gel Strength, 10 minute, lb./100 ft

2

= the maximum dial deflection after 10 min.
