The HTHS Series II is capable of testing at a temperature of 150°C as specified in ASTM D 5481. For other applications, temperature may be set as low as 25°C above ambient.
(DEC99) requires HTHS viscosities from 2.6 to 3.7 mPa•s. Because the HT75 standard has a nominal viscosity of 2.7 mPa•s and the HT150 ® standard has a nominal viscosity of of 3.7 mPa•s, CANNON recom- mends that the users calculate cell volumes using either of these stan- dards.
Operator safety Please observe the following safety procedures and notices for proper operation of your HTHS Series II instrument. Deviation from the installa- tion, operation or maintenance procedures described in this manual may result in a hazardous situation and may void the manufacturer's warranty.

Refer all service and repairs to qualified personnel. • Do not attempt to service the unit beyond the service and/or repair procedures detailed in this manual or other documentation provided by the manufacturer. Contact CANNON ® Instrument Company for all additional service/repair needs.
The container slides into place at the left front of the HTHS Series II. A hinged door provides protection from hot oil. At the rear, an internal fan draws vapors into the exhaust manifold.
HTHS internal rear view including pressure relief rupture disc assembly Thermostat The HTHS Series II is equipped with a thermostat that prevents the instrument from overheating. If temperature rises to an unacceptable level (160°C ± 5°C), power will be removed from the HTHS and will not be restored until the instrument has cooled to a safe state.
Instrument Company immediately. Damaged items Retain all packing materials until the instrument is connected and func- tioning properly. If any component(s) must be returned to CANNON ® Instrument Company, the damaged item(s) should be packaged in the original shipping container. Refer to the final chapter of this manual for instructions on returning defective equipment.
3. Flip the PRESSURE/VACUUM switch to VACUUM and check the adapter for a slight suction with your finger.The VPU has been carefully adjusted at CANNON ® but it may be necessary to readjust the force of the vacuum by turning the ADJUST dial on the front panel of the unit.

The High-Shear Viscosity Calculator is a standalone software package that calculates viscosity of a sample in mPa·s (cP) using efflux time and ® pressure values obtained during testing with the CANNON High- Temperature High-Shear Viscometer (HTHS). The Calculator also provides a routine for ensuring the accuracy of constants used in viscos- ity calculation.
RUN window. Click Open. Then click OK. 2. Follow the installation program prompts to complete the installation. The default path for installation is C:\Program Files\CANNON Instrument Company\HTHS. The setup program will install the High-Shear Viscosity Calculator files to the drive and directory specified.

You may need to practice working with the valve settings to establish the desired pressure in a relatively short time. The internal valve system for the HTHS Series II includes a replaceable CAUTION rupture disc as a safety measure to prevent pressure from rising above 700 psi.
2. Make sure that the waste oil container is in its position at the base of the HTHS under the viscometer cell exit tubes. Cap the HTHS exit tubes to prevent oil leakage during the preliminary part of the test. Satisfactory stoppers are available from CANNON ® (Catalog #9726- N98;...
DO NOT PROCEED TO THE NEXT STEP OF THE RUN PROCEDURE NOTE IF THE PLUG VALVE FOR THE TEST CELL IS IN THE OPEN (HANDLE VERTICAL) POSITION. The HTHS Series II test cycle will not begin unless the plug valve is closed. 9. Remove the adapter from the charge cylinder.

SAE J300 requires HTHS viscosities from 2.6 to 3.7 mPa•s. Because the HT75 standard has a nominal viscosity of 2.7 mPa•s and the HT150 standard has a nominal viscosity of of 3.7 mPa•s, CANNON ® recommends that the users initially calculate cell volumes using either of these standards.
