5. Place the battery inside the compartment and replace the cover, securing it with the screw(s).

4.2. Ukuxhumanisa Abaholi Bokuhlola

The multimeter is supplied with a pair of test leads (red and black).

• Faka i black test lead kwe COM (Common) input jack.
• Ngezilinganiso eziningi (umqulutage, resistance, low current), insert the red test lead kwe VΩmA ujeke wokufaka.
• For high DC current measurements (up to 10A), insert the red test lead kwe Idatha ye-10ADC ujeke wokufaka.

5. Iziqondiso Zokusebenza

To operate the multimeter, select the desired function and range using the rotary switch.

5.1. Measuring DC Voltage (DCV)

1. Insert the red lead into the VΩmA jack and the black lead into the COM jack.
2. Set the rotary switch to the desired DCV range (e.g., 200m, 2000m, 20, 200, 1000). Start with the highest range if the voltage akwaziwa.
3. Xhuma izintambo zokuhlola kulo lonke ingxenye noma isekethe okufanele ikalwe.
4. Funda ivolumutage value kusibonisi se-LCD.

5.2. Ukulinganisa i-AC Voltage (ACV)

1. Insert the red lead into the VΩmA jack and the black lead into the COM jack.
2. Set the rotary switch to the desired ACV range (e.g., 200, 750). Start with the highest range if the voltage akwaziwa.
3. Xhuma izintambo zokuhlola kulo lonke ingxenye noma isekethe okufanele ikalwe.
4. Funda ivolumutage value kusibonisi se-LCD.

5.3. Measuring DC Current (DCA)

1. Kuma-currents afinyelela ku-200mA: Insert the red lead into the VΩmA jack and the black lead into the COM jack.
2. Kuma-currents afinyelela ku-10A: Insert the red lead into the 10ADC jack and the black lead into the COM jack.
3. Set the rotary switch to the desired DCA range (e.g., 200μ, 2000μ, 20m, 200m, 10A). Start with the highest range if the current is unknown.
4. Vala amandla kusekethi. Vula isekethe lapho kuzolinganiswa khona ugesi.
5. Xhuma i-multimeter ngokulandelana nesekethe.
6. Faka amandla kusekethe bese ufunda inani lamanje kusibonisi se-LCD.

5.4. Measuring Resistance (Ω)

4. Xhuma izintambo zokuhlola phezu kwengxenye noma ucingo.
5. If continuity exists (low resistance), the meter will emit an audible tone. The display will show the resistance value.

5.6. Diode/Transistor Verification Mode (hFE)

1. Insert the red lead into the VΩmA jack and the black lead into the COM jack for diode testing.
2. Set the rotary switch to the diode symbol.
3. Xhuma intambo ebomvu ku-anode kanye nentambo emnyama ku-cathode ye-diode. Isibonisi sizobonisa ivolumu yangaphambilinitage drop. Reverse the leads; the display should show 'OL' (open loop) for a good diode.
4. For transistor hFE measurement, insert the transistor leads (Emitter, Base, Collector) into the appropriate sockets (E, B, C) in the hFE test socket, ensuring correct NPN or PNP type selection.
5. Read the hFE value on the LCD display.

6. Isondlo

6.1. Ukuhlanza

Wipe the meter casing nesikhangisoamp indwangu kanye nensipho yokuwasha ethambile. Ungasebenzisi izinto zokukhuhla noma izinyibilikisi. Qinisekisa ukuthi imitha yomile ngokuphelele ngaphambi kokusebenzisa.

6.2. Ukushintshwa Kwebhethri

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

7. Ukuxazulula izinkinga

• Akukho Ukuboniswa: Check battery installation and ensure the battery has sufficient charge.
• 'OL' noma '1' kusikrini: This usually indicates an over-range condition or an open circuit. Select a higher range or check connections.
• Ukufundwa Okungalungile: Ensure the correct function and range are selected. Check test lead connections and battery condition.
• No Continuity Tone: Verify the circuit is de-energized and the leads are making good contact.
