Automeg is an automatic test system, equipped with our MKAT test management software.
The Automeg specification will be confirmed following a discovery call with our sales experts.
We can supply you with the full set of test interface cables, or just the design.
If choosing the full supply option, we'll design, assemble, test and supply the complete cable set. All you have to do is supply the CMM and part mating connectors.
Opting for design only? We'll supply the methods drawing, wiring schedule and parts list.
Save hours of time by ordering the pre-written test programme for your required variant as part of your APU test system solution.
We'll supply the test programme in MKAT format, ready to be used with the Automeg (almost) straight out of the box.
