4.2 Njikọ Ndị Nnwale Nlele

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

• Tinye isi ule ojii ahụ n'ime ihe ntinye 'COM' (nke a na-akpọkarị).
• Maka ọtụtụ nha (mkpụrụ)tage, resistance, continuity, and low current), insert the red test lead into the 'VΩmA' input jack.
• For high current measurements (up to 10A), insert the red test lead into the '10A MAX' input jack.

5. Ntuziaka ọrụ

To operate the multimeter, select the desired function using the rotary switch and connect the test leads to the circuit or component being measured.

5.1 DC Voltage Measurement (V–)

Used for measuring direct current voltage in circuits.

1. Tọọ mgba ọkụ rotary na DC Vol achọrọtage (V–) range (e.g., 200mV, 2V, 20V, 200V, 500V).
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 ngosi.

5.2 AC Voltage Measurement (V∼)

Used for measuring alternating current voltage.

1. Tọọ mgba ọkụ na-agbanwe agbanwe na AC Vol achọrọtage (V∼) range (e.g., 200V, 500V).
2. Jikọọ ụzọ ule n'ofe AC voltage isi iyi.
3. Gụọ voltage uru na ngosi.

5.3 DC Current Measurement (A–)

Used for measuring direct current flowing through a circuit.

1. Ihe dị mkpa: Gbanyụọ ike na sekit ahụ tupu ijikọ multimeter n'usoro.
2. Set the rotary switch to the desired DC Current (A–) range (e.g., 2000uA, 20mA, 200mA, 10A).
3. Insert the red test lead into the appropriate current input jack ('VΩmA' for low current, '10A MAX' for high current).
4. Jikọọ multimeter n'usoro na sekit ahụ, hụ na ugbu a na-agafe mita ahụ.
5. Apply power to the circuit and read the current value on the display.

5.4 Resistance Measurement (Ω)

Used for measuring the resistance of components.

1. Ihe dị mkpa: Ensure the component is isolated from power and discharged before measuring resistance.
2. Set the rotary switch to the desired Resistance (Ω) range (e.g., 200Ω, 2kΩ, 20kΩ, 200kΩ, 2MΩ, 20MΩ).
3. Jikọọ ndị na-enye ule n'ofe akụkụ ahụ.
