Features:

• Characters on the 5-digit display reverse direction depending on which measurement mode you are in.
• Microcomputer LSI circuitry provides accuracy to 0.05% and permits readings to a resolution of 0.1 RPM in either photo or contact mode.
• ABS plastic housing assures years of maintenance free performance.
• Designed to fit comfortably in either hand.
• Ranges from 0.5 to 20,000 RPM in contact mode; from 5 to 99,999 RPM in photo mode; linear surface speed measurements are 0.2 to 6560 fpm or 0.05 to 1999.9 m/min.
• Automatically holds last reading for 5 minutes and recalls minimum and maximum readings.

Accessories Included:

• Rpm adapter (funel)
• Reflective tape
• Carrying case
• Rpm adapter (cone)

How to use

• Contact Tachometer MeasurementsFor RPM Measurements: slide the Function switch to RPM (Contact) position. Press the Measure button while lightly pressing the rotating devise. Release the Measure button when the reading stabilizes (approx. 2 seconds).For Surface Speed Measurements: After you have selected the m/min. (Surface Speed) or ft/min. (Surface Speed) by sliding the Function switch, press the Measure button and simply attach the surface speed test wheel to the detector.
• Memory callThe minimum, maximum and the last (final) readings are automatically stored during measurement. These values can be recalled anytime by pressing the Memory Call button.
• Photo Tachometer MeasurementsUsing the Photo Tachometer’s Function switch select the RPM (Photo) position. Place the reflective tape to the object that will be measured. Press the Measure button and align the visible light beam with the reflective mark. Look on the monitor indicator and see if it lights when the target passes through the light beam. It takes up to 2 seconds until the readings stabilizes. Release the Measure button. In order to obtain greater accuracy for measurement of less than 50 RPM, use 2 or 3 pieces of reflective tape and then divide the reading with the number of pieces used to calculate the final figure.
