____________________________________________ Accuracy We define measurement tolerances in terms of f.s. (full scale), rdg. (reading) and dgt. (digit) values, with the following meanings: f.s. (maximum display value or scale length) The maximum displayable value or scale length. This is usually the name of the currently selected range.
____________________________________________ Notes on Use Follow these precautions to ensure safe operation and to obtain the full benefits of the various functions. DANGER To avoid damage to the instruments and potentially life-threatening hazards, observe the following precautions: Be careful when measuring with the contact adapter because rotation and vibration of the instrument can produce erratic results with either high or low...

____________________________________________ Depending on the material of the object NOTE to be measured or method of touching the contact tip, the measurement error may occur. Do not perform measurements in locations with high humidity or where those are subject to intense ambient light.
____________________________________________ Chapter 1 Overview 1.1 Product Overview This instrument is a non-contact, highly portable tachometer that functions by measuring the visible light reflected from reflective tape attached to the object to be measured. It can also be used as a contact type tachometer by attaching the optional 9213 CONTACT ADAPTER, sold separately.

____________________________________________ (14) MODE symbols Holds maximum reading Holds minimum reading TOTAL Total amount of rotations PERIOD Period of rotation measurement (15) FAST/SLOW Selects the sampling period. mode switch (16) Analog output Selects between x 0.1 (mV) range switch and x 0.01 (mV) for r/min measurement and selects between x 10 (mV) and x 1 (mV) for r/s measurement.
____________________________________________ Chapter 2 Measurement Method 2.1 Measurement Preparations 1. If this is the first time the instrument will be used, insert the batteries. 2. Attach the reflective tape to the rotating object. Before attaching the tape, make sure that the surface of the object is free of dirt, grease or dust.
Page 18
____________________________________________ The red light from the instrument shall NOTE strike the reflective tape at an incidence angle of 45 degrees or less. If the incidence angle exceeds 45 degrees, the instrument may not be able to detect the reflected light and may not be able to do measurement.
The 3404 can also be switched between FAST and SLOW sampling period. On the 3403, the last digit of the display will be fixed to 0 for counts over 20,000. Analog output on the 3404 will match the displayed value.
____________________________________________ When the count exceeds 20,000 on the NOTE 3404 in the SLOW mode, the last digit will be fixed to zero, and, in the FAST mode the last two digits will be fixed to zero. This is the same for MIN and MAX hold modes as well.
____________________________________________ 2.4 MIN Hold Measurement (3404 only) Press the switch to enter the MIN MODE mode. In MIN hold measurement, verify that NOTE the detection LED is lit, and then press switch and begin measurement. RESET ln this mode, like the normal measurement, the speed of rotation is measured, and the minimum detected value is displayed where there is...
____________________________________________ The analog output during MAX and MIN hold measurement is independent of the displayed values, and always represents the normal measurement value. The displayed maximum and minimum values will be cleared with the RESET switch only. The maximum and minimum values won't be cleared by changing the mode with the MODE...
Page 23
____________________________________________ <For example> 3 x 100,000 + 83201 = 383201 When the count exceeds 600,000, the NOTE ----- display shows " " and the instrument stops counting. The counting will continue inside the instrument, even after the switch HOLD is pressed. The measurement value is cleared by pressing the switch.
____________________________________________ 2.6 PERIOD Measurement (3404 only) In this mode the time of the rotation pulse (period) is measured. 1. Press the switch to start MODE PERIOD measurement. 2. For measurement of 2 s and longer, the display will appear as shown below.
Page 25
____________________________________________ Cautions in TOTAL and PERIOD measurement ln TOTAL and PERIOD measurement the measurement value is displayed regardless of changes to r/min/r/s. During the TOTAL and PERIOD measurement, the analog output will be based on results of the NORMAL measurement, regardless of the current display.
____________________________________________ 2.7 FAST/SLOW Mode Measurement (3404 only) The FAST/SLOW mode, switch selects different sampling periods for measurement and display. The sampling period of the analog output is also changed. Do not switch between FAST and NOTE SLOW modes during measurement in the MAX and MIN measurement mode.
____________________________________________ 2.8 Data Hold This is used to freeze (hold) a displayed value when it is difficult to read the display. When the switch is pressed, the HOLD display will be held, and also be suspended. Pressing it for a second time will release the hold.
____________________________________________ 2.9 Buzzer Off Set Turn on the power while holding the switch down. HOLD Keep the HOLD switch depressed until NOTE all the LCD indications light up and then go out (about one second). ____________________________________________ Chapter 2 Measurement Method...
____________________________________________ Chapter 3 Precautions Precautions in Measurement of High-Rotation Objects Detection of reflected light uses modulated light to minimize the effects of incident light. When this modulated light is input for a fixed period of time (about 0.2 ms) or longer, a single pulse is detected.
Page 30
____________________________________________ If the reflective tape cannot be attached within this detection range, increase the area of the reflective tape so that the generated pulse is 0.2 ms or higher. Attach reflective tape Area where reflective tape cannot be attached Rotating body For measurement of 30,000 r/min or higher, use the following method: Rotating body...
