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.

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.

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. The temperatures measured by these thermometers must be adjusted with an offset
value to match the actual temperature of the sample being tested. For example, a temperature
at the thermal core of –40 °C may result in the sample being at –39 °C due to the ambient air
temperature of the lab warming the sample slightly.

The Watlow® controller manages the temperature of the TESC base unit via an RTD probe
located in the thermal core in front of the test chamber. The Watlow® controller displays the
adjusted temperature. In the example, the Watlow® controller displays a temperature of –

40.0 °C, but it is known that the sample is actually at –39.0 °C (see Table 11, row 1). To correct
for this deviation, slightly more than +1 °C is added to the Calibration Offset value of the
Watlow® controller, such as +1.1 °C (see Table 11, row 2). Because the Watlow® controls the
temperature of the TESC core, this adjustment results in the sample gradually cooling to –40.0
°C when the Watlow® controller is programmed to –40.0 °C (see Table 11, row 3).

sample information, add the sample ID.

only small adjustments of ± .1 °C should be necessary to fine tune the
temperature setting.

If desired, the actual temperature of the sample may be determined
using a viscosity calculation tool, such as VISDISK®.

reading to the calibrated viscosity of the sample.

• If the measured viscosity is higher than the calibrated viscosity, then the
temperature of the sample is lower than the target temperature. Subtract 0.1 °C from
the value shown for the Calibration Offset and enter this new value into the
Watlow® configurator program. Continue to step 11.

• If the measured viscosity is lower than the calibrated viscosity, then the temperature
of the sample is higher than the target temperature. Add 0.1 °C to the value shown
for the Calibration Offset and enter this new value into the Calibration configurator
program. Continue to step 11.

• If the measured viscosity is within the tolerance range of the calibrated viscosity of
the sample, the temperature of the sample is correct. Calibration is complete, go to
step 16.
