5. Nhazi

The Qiilu Voltage Tester Pen is ready for use out of the box. No assembly or battery installation is required as it draws power directly from the circuit being tested.

1. Ensure the tester and its probes are clean and free from damage.
2. Familiarize yourself with the voltage indicator lights on the tester body.

6. Ntuziaka ọrụ

Follow these steps to use your voltage tester:

6.1. AC/DC Voltage Nnwale

1. Hold the main body of the tester firmly.
2. Connect the red probe tip to one point of the circuit you wish to test.
3. Connect the black probe tip to the other point of the circuit.
4. Observe the LED indicator lights on the tester. The lights corresponding to the detected voltage level will illuminate. For example, if testing a 12V car battery, the 6V and 12V LEDs should light up.
5. Maka AC voltage, the lights will indicate the approximate voltage range. For DC voltage, the lights will indicate the voltage, and the polarity indicator (+/-) will show the positive or negative terminal.

6.2. Polarity Indication (DC Circuits)

When testing DC circuits, the tester will indicate polarity:

• Ọ bụrụ na '+' LED illuminates, the red probe is connected to the positive terminal and the black probe to the negative terminal.
• Ọ bụrụ na '-' LED illuminates, the red probe is connected to the negative terminal and the black probe to the positive terminal (reverse polarity).

6.3. Screwdriver Function

The tips of both probes can be used as small screwdrivers for light-duty tasks. Ensure the circuit is de-energized before using the probes as screwdrivers to avoid electrical hazards.

7. Nlekọta

To ensure the longevity and accuracy of your voltage tester:

• Nhicha: Wipe the tester with a dry, soft cloth. Do not use abrasive cleaners or solvents.
• Nchekwa: Chekwaa ihe nleba anya n'ebe dị jụụ, kpọrọ nkụ, pụọ na ìhè anyanwụ kpọmkwem na oke okpomọkụ.
• Nyocha: Regularly inspect the probes and cable for any damage or wear. Replace the unit if significant damage is found.
