3. Draai die bevestigingsskroef(e) los en verwyder die deksel.
4. Koppel 'n nuwe 9V-battery aan die batteryklemme en let op die korrekte polariteit.
5. Plaas die battery in die kompartement en plaas die deksel terug en maak dit vas met die skroef(e).

4.2 Toetsdraadverbinding

Connect the test leads to the appropriate input jacks based on the desired measurement:

• COM Jack: Always connect the black test lead to the COM (Common) jack.
• VΩHz-aansluiting: Connect the red test lead for Voltage, Resistance, Frequency, Capacitance, Diode, and Continuity measurements.
• mA Jack: Connect the red test lead for current measurements up to 600mA.
• 20A Jack: Connect the red test lead for current measurements up to 20A.

4.3 Bluetooth App Connection

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. Sodra jy gekoppel is, kan jy view real-time measurements, log data, and analyze trends within the application.

5. Bedryfsinstruksies

5.1 Aan/Af en Funksiekeuse

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 Vlugtage Meting (WS/GS)

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) of V- (GS Voltage) posisie.
3. Raak die toetsprobes aan die stroombaanpunte waar voltage moet gemeet word.
4. Lees die voltage value on the display. The meter supports True RMS for AC measurements.

5.3 Stroommeting (WS/GS)

Waarskuwing: 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. For 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.
4. Maak die stroombaan oop waar die stroom gemeet moet word en koppel die meter in serie.
5. Lees die huidige waarde op die skerm.

5.4 Resistance, Continuity, Diode, and Capacitance Measurement

1. Connect the black lead to COM and the red lead to the VΩHz jack.
2. Rotate the function switch to the Ω (Resistance), →| (Diode), or •))) (Continuity) position. Use the "Select" button to cycle through these functions if they share a single switch position.
3. For resistance, connect probes across the component. For continuity, a beep indicates a continuous circuit. For diode, connect across the diode. For capacitance, connect across the capacitor.
4. Lees die meting op die skerm.

4. Plaas die termokoppelpunt op of naby die voorwerp waarvan die temperatuur gemeet moet word.
5. Read the temperature on the display. Use the "Select" button to switch between Celsius and Fahrenheit.

5.7 Nie-Kontak Voltage (NCV) Opsporing

Die NCV-funksie maak voorsiening vir die opsporing van WS-volumetage sonder direkte kontak.

1. Rotate the function switch to the NCV position.
2. Move the top front part of the multimeter close to the conductor or outlet.
3. The meter will emit an audible beep and the NCV indicator light will flash, indicating the presence of AC voltage.

5.9 Data Logging and Voice Broadcast

When connected via Bluetooth to the OWON app, the multimeter can log data and provide voice broadcast of readings.

• Datalogging: Activate logging within the mobile application. The meter also supports built-in offline recording for up to 7 days, which can be retrieved via the app.
• Stemuitsending: Enable this feature in the app settings to hear readings audibly, which can be useful in situations where viewing the display is difficult.

6. Onderhoud

6.1 Skoonmaak

Vee die meter se kas af met advertensiemateriaalamp 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 Batteryvervanging

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

6.3 Sekeringvervanging

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. Open the battery compartment cover as described in Section 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. Plaas die deksel van die batterykompartement terug en maak dit vas.

6.4 Berging

Wanneer dit nie vir lang tye gebruik word nie, verwyder die battery om lekkasie te voorkom. Bêre die multimeter op 'n koel, droë plek, weg van direkte sonlig en uiterste temperature.
