This document is a user manual for a certain brand of certain model product, which introduces the product's use methods, operation steps and precautions, etc
This manual describes the tachymeter scale printed on the Tachymeter 1260 watch, showing the graduated markings used for measuring speed or frequency. The scale includes divisions such as 260, 500, 400, 300, 250, 200, 180, 160, 140, 120 and 100.
An example calculation is provided: completing 15 jobs in 20 seconds yields a tachymeter figure of 180, which multiplied by the number of jobs (15) gives 2700 jobs per hour. The guide shows how to apply the scale for similar measurements.

First read the tachymeter figure for the time taken (e.g., 180 for 20 seconds), then multiply that figure by the number of jobs completed (e.g., 15) to get 2700 jobs per hour.
The scale includes the numbers 260, 500, 400, 300, 250, 200, 180, 160, 140, 120 and 100.
