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.
Theory of operation
The TESC System uses a method equivalent to Procedure B of ASTM D2983. To reduce test
variability, the TESC System automates or removes many of the steps required to transfer the
sample between conditioning and testing processes. Automation occurs through use of a
thermoelectrically controlled sample chamber that manages the sample, without operator
intervention, throughout the conditioning and testing processes.
Using a calibrated TESC System, an operator runs a D2983 test as follows:
1. Auto-zero the Brookfield® DV2T viscometer.
2. Measure 20 mL of sample into a 25 mm × 150 mm, rimless test tube.
3. Carefully place the test tube with the sample into the TESC sample chamber.
4. Attach a #4B2 spindle to the DV2T and lower the viscometer into the run position.
5. Launch both the temperature control program and the viscometer program.
Once the temperature control program starts, the TESC System heats the sample to the
preheat temperature and maintains it at that temperature for the required time. The TESC
System then cools the sample to room temperature at the same rate used to raise it to the
preheat temperature, and then further cools the sample to the desired test temperature
according to the equation in D2983 Annex A1. This controlled heating and cooling is critical to
reducing variability.
Throughout the thermal conditioning process, the DV2T program records the temperature of
the sample chamber while waiting to measure the viscosity. When thermal conditioning of
the sample completes, the DV2T automatically measures the sample viscosity by stepping

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. The TESC System comes with a set of thermal conditioning programs
for all of the common specification test temperatures as well as certain OEM measurement
and report requirements.

Notes/Cautions/Warnings
Notes, caution, and warnings are used in the manual to call an operator’s attention to
important details prior to performing a procedure or step. Read and follow these important
instructions. Failure to observe these instructions may void warranties, compromise operator
safety, and/or result in damage to the TESC System.
Notes provide more information about the content that follows.
Cautions alert the operator to conditions that may damage equipment.
Warnings alert the operator to conditions that may cause injury.
Safety precautions
Please observe the following general safety precautions for proper and safe operation of the
Thermoelectric Sample Conditioner.
• Only qualified personnel should operate the TESC System.
• Make sure that you read and understand all operating instructions and safety precautions
listed in this manual before installing or operating your unit. If you have questions
regarding instrument operation or documentation, contact CANNON Instrument
Company®.
• Do not deviate from the installation, operation, or maintenance procedures described in
this manual. Improper use of the TESC System may result in a hazardous situation and
may void the manufacturer’s warranty.
• Handle and transport the unit with care. Sudden jolts or impacts may cause damage to
components.
• Observe all warning labels. Never remove warning labels.
• Never operate damaged or leaking equipment.
