While this test was performed on the 257D and the specifications given were for this unit, the way the test is performed as well as the generic specifications are transferable to other models and manufacturers.

Always make sure to check service manuals, lock out and de-energize systems before opening them and working on them. High pressure injection injuries can happen if safety is not prioritized and best practices followed.

Happy Testing
