Calibrating the TESC System CANNON®
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. After the 2 hour soak and initial test, only 1 hour is required
between tests for small temperature adjustments to stabilize.
Ignore the temperature recorded by the DV2T. It may not be accurate,
but this will not affect the calibration of the Watlow® controller.
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. Press red EZ button on the Watlow® controller.
8. Wait for the DV2T test to complete.
Note: The computer only needs to be connected to the TESC System
and Watlow® configuration program only needs to be running when
you are actively changing the Watlow® controller. During test runs, the
computer may be disconnected from the TESC System.
9. If it is not already running, start Watlow® configurator program:
a. Launch Watlow® configurator program: Start Menu > EZ-ZONE Configurator > EZ-
ZONE Configurator .
b. Select Configure a device while communicating with it . Click Next .
c. Select the COM port to which the Watlow® controller is connected. Click Next .
d. Select the TESC System from the list of available EZ-ZONE Devices. Click Next .
