3. Nhazi

3.1. Ntinye batrị

1. Ensure the multimeter is turned OFF and all test leads are disconnected.
2. Locate the battery compartment cover on the back of the meter (refer to Figure 1).
3. Unscrew the retaining screw(s) and carefully remove the cover.
4. Insert a new 9V battery (NEDA 1604 or 6F22 type), observing the correct polarity (+ and -).
5. Replace the battery compartment cover and secure it with the screw(s).

3.2. Ijikọ ụzọ ule

• Jikọọ uhie test lead to the "VΩmA" input jack.
• Jikọọ nwa test lead to the "COM" (common) input jack.
• For current measurements exceeding 200mA (up to 10A), connect the red test lead to the "10A" input jack.

4. Ntuziaka ọrụ

4.1. Nhọrọ ọrụ

Turn the rotary switch to the desired measurement function and range. Always start with a higher range if the approximate value is unknown to prevent overloading the meter.

4.2. Ịtụ DC Voltage (V–)

1. Tọọ mgba ọkụ rotary na DC Vol achọrọtage (V–) range (e.g., 20V, 200V).
2. Jikọọ ihe nlele uhie ahụ n'akụkụ dị mma (+) nke sekit ahụ, tinyekwa ihe nlele ojii ahụ n'akụkụ adịghị mma (-).
3. Gụọ voltage uru na LCD ngosi.

4.3. Atụ AC Voltage (V∼)

1. Tọọ mgba ọkụ na-agbanwe agbanwe na AC Vol achọrọtage (V∼) range (e.g., 200V, 750V).
2. Jikọọ ụzọ ule n'ofe AC voltage isi iyi.
3. Gụọ voltage uru na LCD ngosi.

4.4. Measuring DC Current (A–)

Ịkpachara anya: To measure current, the meter must be connected in series with the circuit. Never connect the meter in parallel with a voltage source when in current mode, as this can damage the meter and the circuit.

1. Set the rotary switch to the desired DC Current (A–) range (e.g., 20mA, 200mA, 10A).
2. For currents up to 200mA, ensure the red lead is in the "VΩmA" jack. For currents up to 10A, move the red lead to the "10A" jack.
3. Open the circuit where current is to be measured and connect the meter in series.
4. Gụọ uru dị ugbu a na ngosipụta LCD.

4.5. Nguzogide Ịtụ (Ω)

Ịkpachara anya: Ensure the circuit or component under test is de-energized before measuring resistance.

1. Set the rotary switch to the desired Resistance (Ω) range (e.g., 200Ω, 2kΩ, 200kΩ).
2. Jikọọ ụzọ ule n'ofe akụrụngwa ma ọ bụ sekit a ga-atụ.
3. Gụọ uru iguzogide na ngosipụta LCD.

4.6. Diode Test (→|–)

1. Set the rotary switch to the Diode Test (→|–) position.
2. Connect the red test lead to the anode of the diode and the black test lead to the cathode.
3. Ngosipụta ga-egosi volta n'ihutage drop (typically 0.5V to 0.8V for silicon diodes).
4. Weghachite ụzọ. Ngosipụta kwesịrị igosi "OL" (Open Loop) maka ezigbo diode.

4.7. Transistor (hFE) Test

1. Tọọ ngbanwe rotary na ọnọdụ hFE.
2. Identify if the transistor is NPN or PNP.
3. Insert the transistor's emitter, base, and collector leads into the corresponding sockets on the hFE test socket.
4. Read the hFE (DC current gain) value on the display.

5. Nlekọta

5.1. Ngbanwe batrị

When the low battery indicator appears on the display, replace the 9V battery as described in Section 3.1. Using a low battery can lead to inaccurate readings.

5.2. Fose nnọchi

If the current measurement function stops working, the fuse may need replacement. This operation should only be performed by qualified personnel.

1. Ensure the multimeter is turned OFF and all test leads are disconnected.
2. Open the back casing of the meter (this may involve more screws than just the battery compartment).
3. Locate the blown fuse and replace it with a fuse of the exact same type and rating (e.g., F200mA/250V for mA range, F10A/250V for 10A range). Refer to the internal markings or specifications for precise fuse ratings.
4. Carefully reassemble the meter, ensuring all screws are tightened.

5.3. Nhicha

Jiri mgbasa ozi hichaa mita ahụamp cloth and mild detergent. Do not use abrasives or solvents. Keep the meter dry.
