5. ຕັ້ງຄ່າ

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. ຄໍາແນະນໍາການດໍາເນີນງານ

Follow these steps to use your voltage tester:

6.1. AC/DC Voltage ການທົດສອບ

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. ສໍາລັບ 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:

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

6.3. ໜ້າທີ່ຂອງໄຂຄວງ

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.
