Latest Update to Kepler 4

About AWS

We have just released the latest major update to our torque tool calibration and certification software for ISO 6789:2017, Kepler 4. This update brings several major benefits with more seamless operation and improved efficiency. It gives users the ability to:

- Store databases on a server rather than individual machines.

- Calibrate tools with a HEX drive or one that has equal positions divisible by 6 to ISO 6789:2017 Part 2.

- Search for tools by models using the models database.

- Calculate average values of uncertainties bod, bint and bl over the last 10 calibrated tools of the same model.

- Import databases from previous versions of Kepler.

- Export reports into text or CSV formats and reimport them.

ISO 6789 is the internationally recognised standard to which torque wrenches must be calibrated.

A calibration certificate to ISO 6789 states that a tool meets quality control regulations and accurately applies the correct torque.

AWS have produced a white paper highlighting the main changes and requirements. It can be viewed by clicking below:
