The paper chart is driven past the pen at a steady rate by a clockwork or electrical drive mechanism. One common method is to use a miniature synchronous motor which turns at a constant speed related to the power frequency; a gear-train is used to propel the paper. Industrial strip-chart recorders may have two-speed gear trains that allow a ...
Electronic test equipment is used to create signals and capture responses from electronic devices under test (DUTs). In this way, the proper operation of the DUT can be proven or faults in the device can be traced. Use of electronic test equipment is essential to any serious work on electronics systems.
The Scherbius Drive is an electrical drive system invented by Arthur Scherbius, a German engineer known for his work in electrical engineering and cryptography (he also invented the Enigma machine). This drive system is primarily associated with controlling the speed of electric motors , particularly asynchronous (induction) motors.
Automatic test equipment diagnostics is the part of an ATE test that determines the faulty components. ATE tests perform two basic functions. The first is to test whether or not the Device Under Test is working correctly. The second is when the DUT is not working correctly, to diagnose the reason.
Instrument mechanics in engineering are tradesmen who specialize in installing, troubleshooting, and repairing instrumentation, automation and control systems.The term "Instrument Mechanic" came about because it was a combination of light mechanical and specialised instrumentation skills.
