Digital Circuit Breaker Finder

Product Introduction

Dear user, thank you for purchasing this product. Read the instructions carefully before use.

The NF-827 is a socket line sequence detection and Digital Circuit Breaker Finder. This instrument is suitable for home, factory, and all kinds of large construction sites. It is composed of a socket tester and a receiver.

The receiver has high sensitivity and strong anti-interference ability, which is used to find the corresponding air opening of the power socket or fixed panel in the circuit.

It also supports socket testing. Plug the socket tester into the power socket, and you can test the socket wiring.

Product Functions

1. Socket Test

Insert the socket tester into the socket. (See Figure 1.1)

Judge the test result according to the test light on/off. (See Figure 1.2)

Note: When geodesic, please short press the "⚡" key, "⚡" appears, indicating the lack of ground. Other functional tests show results directly.

2. Air Switch Detection

Insert the socket tester into the socket. (See Figure 2.1)

Long press the "⚡" key of the receiver for 1 second to turn on the machine. The probe lights up orange, indicating that the air switch is in line finding mode.

Open the distribution box cover. Use the receiver probe close to the air switch panel and detect one by one. When the probe is close to the target air switch, the instrument will emit a "beep" sound, and the probe will light up purple. The closer the probe is to the target air switch, the faster the "beep" sound will be, and the purple light of the probe will be brighter, so as to find the target air switch. (See Figure 2.2)

Long press the "⚡" key again for 2 seconds to power off.

3. NCV Electronic Pen

Press the "⚡" button when the receiver is turned on. The probe indicator switches to green, indicating NCV mode is turned on. (See Figure 3)

When the probe is near an outlet or a live wire, the instrument will emit a "drip" sound, indicating that there is power.

Press the "⚡" button again, the probe will change back to the orange light, indicating that the current air switch line finding mode is back.

Long press the "⚡" key for 2 seconds and the indicator light of the probe goes off.

4. Lighting Function

When the receiver is turned on, press the "⚡" key and the lighting light will turn on. Press the "⚡" button again, and the light goes out. (See Figure 4)

5. Low Power Prompt

When the battery power of the receiver is too low, the probe indicator light flashes. Please replace the battery in time.

If the power is lower than 6.8V, the receiver will automatically shut down.
