5. Asennus ja akun asennus
5.1 Akun asennus
- Paikanna laitteen takaosassa oleva paristolokeron kansi.
- Avaa kansi liu'uttamalla tai ruuvaamalla sitä auki.
- Insert four 1.5V LR6 (AA) batteries, ensuring correct polarity (+/-).
- Sulje paristolokeron kansi kunnolla.
5.2 Heijastinnauhan kiinnittäminen
For accurate non-contact measurement, apply a piece of reflective tape to the rotating object whose speed or count you wish to measure. Ensure the tape is clean and securely attached.
6. Käyttöohjeet
6.1 Virta päälle/pois
Paina HOLD / ON/OFF button to turn the tachometer on or off.
6.2 Kierrosluvun mittaus
- Ensure the device is in RPM measurement mode (indicated on the LCD). If not, press the R/C painiketta vaihtaaksesi.
- Point the laser beam at the reflective tape on the rotating object.
- Maintain a measurement distance between 50mm and 200mm (2 to 8 inches) from the target.
- The RPM reading will be displayed on the LCD.
- Huomautus: If no signal is detected within 7 seconds, the LCD will display "0.0000". If the RPM exceeds 99999, the LCD will display "OL" (Overload).
Image 6.1: Illustrates the correct distance and method for RPM measurement.
6.3 Counts Measurement
- Paina R/C button to switch to Count measurement mode.
- Point the laser beam at the reflective tape on the object.
- The device will count the number of times the laser beam reflects off the tape.
6.4 Mode Selection (MAX/MIN/AVG)
Paina M/M/A button repeatedly to cycle through the following display modes:
- MAX: Näyttää mitatun suurimman arvon.
- MIN: Displays the minimum measured value.
- AVG: Displays the average measured value.
- Normaali: Displays the current real-time measurement.
6.5 Tietojen säilytys
During measurement, a short press of the HOLD / ON/OFF button will freeze the current reading on the display. Press it again to release the data hold and resume live measurement.
6.6 Sampling-nopeuden säätö
Sampling rate can be adjusted from 0.5 to 255 seconds. Refer to the detailed user manual for specific steps on how to access and change this setting via the MENU ja VIRITTÄÄ painikkeita.
6.7 USB Interface (UT372 Only)
The UT372 model features a USB port for connecting to a computer. Use the provided USB cable and PC software CD to transfer measurement data for analysis and logging. Follow the instructions provided with the software for installation and operation.
