During the production of electric motors, the speed is to record at a certain current consumption during the final test.
This requires a speed-measuring device, which quickly and precisely measures and saves the speed.
Here, a calibrated measuring system is desired, too.
With the digital hand-tachometer rotaro, a mechanical adapter and probe tip are used to measure the rotational speed of the motor and store it in the memory.
The value is retrieved later and recorded in the test log together with the current consumption.
The digital hand-tachometer redpoint can also be used to measure the speed visually without contact, using a reflective strip.
