• VΩHz priključek: Connect the red test lead for Voltage, Meritve upornosti, frekvence, kapacitivnosti, diod in prevodnosti.
• mA vtičnica: Connect the red test lead for current measurements up to 600mA.
• 20A vtičnica: Connect the red test lead for current measurements up to 20A.

4.3 Povezava z aplikacijo Bluetooth

The OW18B supports Bluetooth 4.0 for wireless data transmission to a mobile application (Android/iOS) or Windows software.

1. Download the official OWON multimeter application from your device's app store (e.g., Google Play Store, Apple App Store) or the OWON website for Windows software.
2. Ensure Bluetooth is enabled on your mobile device or computer.
3. Power on the OW18B multimeter.
4. Open the OWON application. The app should automatically detect and connect to the OW18B. Follow any on-screen prompts for pairing if necessary.
5. Ko ste povezani, lahko view real-time measurements, log data, and analyze trends within the application.

5. Navodila za uporabo

5.1 Vklop/izklop in izbira funkcij

To power on the multimeter, rotate the function switch from "OFF" to the desired measurement function. To power off, rotate the switch back to "OFF".

5.2 letniktagMerjenje (AC/DC)

1. Connect the black lead to the COM jack and the red lead to the VΩHz jack.
2. Rotate the function switch to the V~ (AC Voltage) ali V- (DC Voltage) položaj.
3. Dotaknite se merilnih sond točk vezja, kjer je voltage je treba izmeriti.
4. Preberite zvtage value on the display. The meter supports True RMS for AC measurements.

5.3 Merjenje toka (izmenični/enosmerni tok)

Pozor: Never connect the meter in parallel to a voltage source when measuring current. This can damage the meter and pose a safety risk.

1. For mA: Connect the black lead to COM and the red lead to the mA jack.
2. Za 20A: Connect the black lead to COM and the red lead to the 20A jack.
3. Rotate the function switch to the A~ (AC Current) or A- (DC Current) position.

6. Vzdrževanje

6.1 Čiščenje

Obrišite ohišje merilnika z oglasomamp cloth and mild detergent. Do not use abrasives or solvents. Ensure the meter is powered off and disconnected from any circuits before cleaning.

6.2 Zamenjava baterije

Refer to Section 4.1 for battery installation instructions. Replace the 9V battery when the low battery indicator appears on the display.

If the current measurement function fails, the fuse may need replacement.

1. Ensure the multimeter is powered off and all test leads are disconnected.
2. Odprite pokrov predalčka za baterije, kot je opisano v poglavju 4.1.
3. Locate the fuse(s) inside the compartment. The OW18B typically uses two fuses: a fast-acting 600mA/250V fuse for the mA range and a fast-acting 20A/250V fuse for the 20A range.
4. Carefully remove the blown fuse and replace it with a fuse of the exact same type and rating.
5. Ponovno namestite pokrov prostora za baterije in ga pritrdite.

6.4 Shranjevanje

Ko multimetra dalj časa ne uporabljate, odstranite baterijo, da preprečite puščanje. Multimeter shranjujte na hladnem in suhem mestu, stran od neposredne sončne svetlobe in ekstremnih temperatur.
