TESC Operator's Manual, Rev 1.0

Calibrating the TESC System CANNON®

During testing, the Brookfield® viscometer measures and records the temperature of the TESC

base unit via an RTD probe located in the thermal core behind the test chamber. Adjusting

the offset of the Brookfield® viscometer only enables the recording of an accurate sample

temperature. It does not affect the operation of the TESC System.
