  3. EDN Test equipment for a production line should be user-friendly (read “idiot-proof”) and should offer minimal test time. In many cases, the test fixture must give an operator only one answer: pass or fail. Usually, two indicators ...

  4. EDN The simplest technique for measuring current in an actuator or a motor is to monitor the ground current with a resistive element between the load and the ground. Because the device and its associated electronics share a ground potential, you ...
