6. Операција

This section details how to use your Jectse AR925 Digital Contact Tachometer for various measurements.

6.1 Укључивање/искључивање

• Да бисте укључили уређај, притисните ON/NULL дугме.
• The device will automatically power off after approximately 30 seconds of inactivity to conserve battery life. There is no dedicated 'off' button.

6.2 Attaching Contact Probes

Select the appropriate contact head (Linear Circular, Speed Column, Speed Large Cone, or Speed Small Cone) based on the object to be measured. Gently push and twist the chosen probe onto the Contact Rotate Head until it is securely attached.

6.3 Мерења

1. Ensure the correct contact probe is attached.
2. Притисните тастер ON/NULL button to power on the tachometer.
3. Gently press the rotating part of the contact probe against the center of the rotating shaft or surface of the object you wish to measure. Maintain steady contact.
4. The LCD display will show the real-time measurement.
5. To change the measurement unit (RPM, m/min, ft/min), press the УНИТ дугме.

6.4 Viewing Stored Values (MAX/MIN/LAST)

The tachometer automatically stores the maximum, minimum, and last measured values. To view these:

• Након мерења, притисните дугме МЕМ дугме.
• Сваки притисак на МЕМ button will cycle through the MAX, MIN, and LAST recorded values.
• The display will indicate which value is currently shown (e.g., "MAX", "MIN", "LAST").

7. Одржавање

Proper maintenance ensures the longevity and accuracy of your tachometer.

• Чишћење: Обришите уређај меком, сувом крпом. Не користите абразивна средства за чишћење или раствараче.
• Складиштење: When not in use for extended periods, remove the batteries to prevent leakage. Store the tachometer and its accessories in the provided carrying bag in a cool, dry place, away from direct sunlight and extreme temperatures.
• Брига о сонди: Inspect contact probes regularly for wear or damage. Replace if necessary to maintain measurement accuracy. Avoid exposing rubber tips to high temperatures, as they may melt.
