FAQs

1. Can the Automatic Engine Oils Apparent Viscosity Tester store previous test results for reference?

It Automatic Engine Oils Apparent Viscosity Tester is equipped with internal memory to store multiple test results. Users can retrieve previous data through the touchscreen interface or export it to a computer or printer. This feature is especially useful for batch testing or long-term analysis of lubricant stability. It supports data logging to help with compliance documentation and audit readiness.

2. Is it possible to perform manual testing on the Automatic Engine Oils Apparent Viscosity Tester ?

The Automatic Engine Oils Apparent Viscosity Tester provides manual mode options despite being a fully automated system. Users can manually adjust test parameters, control temperature settings, or initiate result printouts. This is particularly useful for non-standard methods, troubleshooting, or method development. It ensures consistent test results through automation while allowing flexibility when needed.

3. How does the Automatic Engine Oils Apparent Viscosity Tester simulate cold cranking conditions?

It Automatic Engine Oils Apparent Viscosity Tester simulates cold cranking by rapidly cooling the engine oil sample to sub-zero temperatures and applying a high shear rate (10?–10??s?¹) using a rotor-stator mechanism. The resistance to rotation reflects the oil’s apparent viscosity under engine-startup conditions. This method accurately replicates the stress motor oils face during cold engine starts. It delivers precise data that correlates with real-world oil performance.

4. Can the Automatic Engine Oils Apparent Viscosity Tester be integrated with external data systems or PCs?

Automatic Engine Oils Apparent Viscosity Tester features and interfaces for external connectivity. Users can transfer test results to computers for detailed analysis, reporting, or archival. This supports integration with laboratory information management systems (). It makes data handling efficient for both quality control and documentation purposes.

5. What should be done if the Automatic Engine Oils Apparent Viscosity Tester fails to reach the target temperature?

Automatic Engine Oils Apparent Viscosity Tester may fail to reach the desired low temperature if the ambient conditions are not ideal. Ensure that the surrounding temperature remains within the recommended 15–30?°C range and verify that the ventilation ports are unobstructed. Also, check if the refrigeration system is functioning correctly and that the power supply is stable. If the issue continues, refer to the user manual or contact us support for technical assistance.
