4.1 પાવર ચાલુ/બંધ

Press the red power button (O) to turn the device on. Press and hold the power button to turn it off.

4.2 Selecting Measurement Mode and Units

The TA500 series supports different measurement modes and units. Press the "UNIT" button to cycle through available units and modes (e.g., RPM, ft/m/s, m/min). The selected mode will be displayed on the LCD screen.

4.3 Non-Contact (Photoelectric) Measurement (TA500A/TA500C)

This mode uses a semiconductor laser sensor to measure rotational speed without physical contact.

1. Ensure the tachometer is in a non-contact RPM mode (indicated by a specific icon on the display, typically a target symbol).
2. Attach a reflective tape (not included, but commonly used with such devices) to the rotating object.
3. Point the laser beam from the tachometer at the reflective tape on the rotating object. The effective measurement distance is 50-500 mm.
4. Press the "TEST" button. The measurement symbol on the display will flash, and the RPM reading will appear.
5. Release the "TEST" button to stop measurement.

4.4 Contact Measurement (TA500B/TA500C)

This mode uses physical contact with the rotating object via an attached accessory.

1. Attach the appropriate contact accessory (e.g., cone or wheel) to the tachometer's shaft.
2. Ensure the tachometer is in a contact measurement mode (indicated by a contact icon on the display, typically a 'T' or similar).
3. Gently press the contact accessory against the center of the rotating object or surface.
4. Press the "TEST" button. The measurement symbol on the display will flash, and the RPM or linear speed reading will appear.
5. Release the "TEST" button to stop measurement.

4.5 MAX/MIN/HOLD Functions

• પકડી રાખવું: Press the "HOLD" button to freeze the current reading on the display. Press it again to resume live measurement.
• મહત્તમ/મિનિટ: During measurement, press the "MAX" button to display the maximum recorded value. Press "MAX" again to display the minimum recorded value. Press a third time to return to live measurement.

5. જાળવણી

5.1 સફાઈ

Wipe the device with a soft, dry cloth. Do not use abrasive cleaners or solvents. Keep the sensor lens clean for accurate non-contact measurements.

5.2 સંગ્રહ

When not in use for extended periods, remove the batteries to prevent leakage. Store the tachometer in a cool, dry place, away from direct sunlight and extreme temperatures. The included cloth bag can be used for protection during storage and transport.

5.3 બેટરી રિપ્લેસમેન્ટ

Replace batteries when the low battery indicator appears on the display to ensure continued accurate operation.

6. મુશ્કેલીનિવારણ

• ઉપકરણ ચાલુ થતું નથી: બેટરી ઇન્સ્ટોલેશન તપાસો અને ખાતરી કરો કે બેટરી ખાલી નથી થઈ ગઈ. જો જરૂરી હોય તો બદલો.
• અચોક્કસ વાંચન:
  • For non-contact measurement, ensure the reflective tape is properly applied and the laser is aimed correctly. Verify the measurement distance is within 50-500 mm.
  • For contact measurement, ensure the contact accessory is firmly attached and making proper contact with the rotating object.
  • Ensure the correct measurement mode and units are selected.
• ડિસ્પ્લે ખાલી છે અથવા ઝબકતું છે: Low battery power may be the cause. Replace batteries.
