The stopwatch features a 40-minute dial with a retrograde minute hand. The stopwatch can consecutively measure up to 120 minutes in 1/100-second increments. When the measurement reaches 120 minutes, the stopwatch automatically stops counting. Split time measurement is possible. After 3 minutes of timing from a start, the STOPWATCH 1/100-second and 1/10second hands remain pointing to the "0" position until the watch is stopped or split time measurement is made, at such a time, they move to display the measured time. They start to move for a maximum of three minutes after the watch is restarted or the split time display is released. English 901 8 7 654 * 2 3 The display illustrated at the left should be read as "19," not "29." When the 1/100-second hand is moving toward larger numbers, the 1/10 second hand comes close to the next marker, which may cause you to wrongly read the hands as "29." The time measured is indicated by the four stopwatch hands below. STOPWATCH 1/100-second hand 901 8 7 654 2 3 STOPWATCH 1/10-second hand STOPWATCH second hand · When the minute counting reaches 40 minutes, the STOPWATCH minute hand immediately returns and continues counting from 41 minutes onward. The minute counting is repeated in the same manner for another rotation, up to 120 minutes, at that time the stopwatch automatically stops. · The final position of the STOPWATCH minute hand, after completing 120 minutes of counting, is illustrated below. 20 10 0 30 40 20 10 0 30 40 STOPWATCH minute hand 12 · Before starting to use the stopwatch again, make sure to reset the stopwatch by pressing Button B. 13 English Accumulated elapsed time measurement English While the STOPWATCH hands are moving 1.

Each of the four STOPWATCH hands demonstrates high-speed movements and when the demonstration is finished, they return to the original position. TACHYMETER (for models with tachymeter scale on the dial) To measure the hourly average speed of a vehicle English Ex. 1 1 Use the stopwatch to determine How to view the demonstration 1. Reset the stopwatch. * Refer to "HOW TO USE THE STOPWATCH" section of this manual. 901 8 7 654 2 3 how many seconds it takes to go 1 km or 1 mile. 2 Tachymeter scale indicated by STOPWATCH second hand: 40 seconds Tachymeter scale: "90" "90" (tachymeter scale figure) x 1 (km or mile) = 90 km/h or mph 2. Press Button B for 2 seconds or longer. 10 0 STOPWATCH second hand gives the average speed per hour. 20 30 40 B * * 16 After approximately 3 seconds, the demonstration finishes, and the stopwatch is reset for the next use. If either Button A or B is pressed during a demonstration, the demonstration will be stopped and the stopwatch will be reset. Tachymeter scale can be used only when the time required is less than 60 seconds. Ex. 2: If the measuring distance is extended to 2 km or miles or shortened to 0.5 km or miles and STOPWATCH second hand indicates "90" on tachymeter scale: "90" (tachymeter scale figure) x 2 (km or mile) = 180 km/h or mph "90" (tachymeter scale figure) x 0.5 (km or mile) = 45 km/h or mph 17 English To measure the hourly rate of operation Ex. 1 1 TELEMETER (for models with telemeter scale on the dial) STOPWATCH second hand: 20 seconds The telemeter can provide a rough indication of the distance to the source of light and sound. The telemeter indicates the distance from your location to an object that emits both light and sound. For example, it can indicate the distance to the place where lightning struck by measuring the time elapsed after you see a flash of lightning until you hear the sound. A flash of lightning reaches you almost immediately while the sound travels to you at a speed of 0.33 km/second. The distance to the source of the light and sound can be calculated on the basis of this difference. The telemeter scale is so graduated that the sound travels at a speed of 1 km in 3 seconds.* * Under the condition of temperature of 20 ºC (68 ºF). English Use the stopwatch to measure the time required to complete 1 job. Tachymeter scale indicated by STOPWATCH second hand gives the average number of jobs accomplished per hour. 2 Tachymeter scale: "180" "180" (tachymeter scale figure) x 1 job = 180 jobs/hour Ex. 2: If 15 jobs are completed in 20 seconds: "180" (tachymeter scale figure) x 15 jobs = 2700 jobs/hour CAUTION The telemeter provides only a rough indication of the distance to the place where lightning struck, and therefore, the indication cannot be used as the guideline to avoid the danger of lightning. It should also be noted that the speed of the sound differs depending on the temperature of the atmosphere where it travels. 18 19 HOW TO USE THE TELEMETER BATTERY CHANGE English English Before beginning, check that the stopwatch has been reset. 3 START (Flash of light) 1 Press button A to start the Years stopwatch as soon as you see the light. STOP (Crash of thunder) 2 When you hear the sound, press button A to stop the stopwatch. Read the telemeter scale that the stopwatch second hand points to. The miniature battery which powers your watch should last approximately 3 years. However, because the battery is inserted at the factory to check the function and performance of the watch, its actual life once in your possession may be less than the specified period. When the battery expires, be sure to replace it as soon as possible to prevent any malfunction. For battery replacement, we recommend that you contact an AUTHORIZED SEIKO DEALER and request SEIKO SR927W battery. * If the stopwatch is used for more than 2 hours a day, the battery life may be less than the specified period. * After the battery is replaced with a new one, set the time/calendar and adjust the stopwatch hand position. 3 Approx. 3 km Please note that the stopwatch second hand moves in 1-second increments and does not always point exactly to the graduations of the telemeter scale. The telemeter scale can be used only when the measured time is less than 60 seconds. 20 Battery life indicator When the battery nears its end, the small second hand moves at two-second intervals instead of normal one-second intervals. In that case, have the battery replaced with a new one as soon as possible. * The watch remains accurate while the small second hand is moving at two-second intervals. 21 English WARNING Do not remove the battery from the watch. If it is necessary to take out the battery, keep it out of the reach of children. If a child swallows it, consult a doctor immediately.
