Reference: Special Instruction, SEHS8854, "Using the 1U6602 Photo-Tach Group. "
The 1U6602 Tachometer Group provides an accurate, digital, noncontact, method for the measurement of rotational engine speed. It measures revolutions per minute by directing an integral light source onto a reflective marker on the rotating object and counting the reflected light pulses. The 1U6602 Tachometer Group can be used to measure the rotational speed on any product where a piece of reflective tape can be placed.
With a 4 1/2 digit liquid crystal display (LCD), the 1U7771 Tachometer provides noncontact measurement of rotational speed over the range of 50 to 20,000 rpm with an accuracy of 1 ± rpm. The Special Instruction gives details on specifications, operation, warranty and repair.
