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.
