TESC Operator's Manual, Rev 1.0 Overview CANNON®’s Thermoelectric Sample Conditioner (TESC) System provides controlled sample heating and cooling for ASTM D2983. Low cost and a small footprint, compared to other sample conditioning options, allow several complete TESC Systems to be conveniently operated in the same bench-top area as a single competitor unit. This gives labs optimal test versatility and redundancy to maximize productivity and reduce downtime.
TESC Operator's Manual, Rev 1.0 through the typical range of spindle speeds for the sample type or expected viscosity. This eliminates the need to run multiple tubes of a sample. Once the viscosity measurements finish, the TESC System returns the sample to room temperature, nominally 25 °C. Afterwards, the operator can review the data and enhance the digital record with notes and additional information.

TESC Operator's Manual, Rev 1.0 Note: The 2 hour DV2T calibration program waits 2 hours for the temperature of the sample to stabilize, and then it runs a viscometery test. 5. Insert the USB flash drive into any one of the USB connections on the back of the DV2T. 6. Load and run the 2 hour DV2T temperature calibration program: a. From the DV2T Main Menu, select Load Test > Viscosity Tests > USB 1 > Calibration > CalibTemp2hr-dv2t.dvt. b. Click Run. 7.

TESC Operator's Manual, Rev 1.0 Calibrating the TESC System CANNON Instrument Company® calibrates all TESC Systems as part of the manufacturing process. However, differing ambient conditions during usage may necessitate adjusting the offset values applied to the Watlow® controller and Brookfield® viscometer to ensure accurate results. Two resistance thermometers installed in the thermal core monitor the temperature of the unit.
TESC Operator's Manual, Rev 1.0 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.
TESC Operator's Manual, Rev 1.0 Calibration procedure Use the following procedure to calibrate the Watlow® controller. 1. Turn on DV2T and TESC. If the Watlow® controller starts to run a program, press the red EZ button to halt the test. (Steps symbol indicates a running program.) Note: The 8 hour TESC calibration program lowers the temperature of the sample to the desired soak temperature and maintains that temperature for 8 hours, allowing the operator to run multiple calibration tests. 2.
TESC Operator's Manual, Rev 1.0 4. Prepare a 20 mL sample according to your laboratory practices: a. Insert a 25 mm × 150 mm test tube containing 20 mL (± 0.2 mL) of the reference sample into the test chamber and gently hand-tighten the cone ring. b. Attach a clean #4B2 spindle to the viscometer. c. Carefully lower viscometer into measurement position. Note: The 2 hour DV2T calibration program waits 2 hours for the temperature of the sample to stabilize, and then it runs a viscometery test.
TESC Operator's Manual, Rev 1.0 e. In the Parameter Menus, open EZ-ZONE PM > Setup > Analog Input. The Calibration Offset is shown in the display window. 10. When the DV2T test completes, save the test data from the DV2T to a CSV file on a USB drive and transfer it to the PC. On the PC, use a spreadsheet to open the CSV file. In the sample information, add the sample ID. Note: Because the TESC System is calibrated during manufacturing, only small adjustments of ± .
TESC Operator's Manual, Rev 1.0 12. Load and run the 1 hour DV2T temperature calibration program: a. From the DV2T Main Menu, select Load Test > Viscosity Tests > USB 1> Calibration > CalibTemp1hr-dv2t.dvt. b. Click Run. 13. Wait for the DV2T test to complete. 14. Repeat steps 8 through 14 as needed. Step 12 only needs to be performed one time. 15. Record the offset value. You will need to enter it into each TESC temperature control program prior to running it. 16.
