Jul 22,  · In this video, I teardown and explain how a digital tape measure works. It uses an incremental rotary encoder in combination with an absolute optical encode. How a tape measure works are basically not rocket science. It only depends on its two major features: lock and spring mechanism. The lock button behaves to stop the tape from retracting when you extend it. The spring mechanism plays as the automatic roller to retract the tape. Press the BLADE LOCK button, display “locks in“ current measurement. Release BLADE LOCK button, display is cleared and ready to take next measurement. Download/Print. DUAL MEMORY. Press M1 (in How Does Digital Tape Measure Work Journal red) or M2 (in red) for 1 second, you will see M1 or M2 on .
The process is similar to using a conventional tape measure, except you use a laser beam instead of metal tape. Once you have the laser at the right spot, press the button, and the tape measure calculates the distance and Measure King Digital Tape Measure Review Work displays it on its screen. Mar 14,  · Tape measures are relatively safe and easy to use. Extend the tape from point to point placing the end-clip at the location you want to measure from. Most tape measures have a clip that can be attached to a fixed object to measure spans easily. Many steel blade tapes have tension-control brakes that lock the blade in place for measuring spans. The DG is the opposite of the circuit you have in mind, i.e. it's a digital-to-time converter, but in my mind somewhat easier to understand than the circuit of the same company's SR Time interval/frequency counter, which does the time-to-digital conversion that How Does Digital Tape Measure Work Visible you were asking about.
