A. Non-Contact Voltage Tester and LED Diagnostic Pen
Product Overview:
The Non-Contact Voltage Tester and LED Diagnostic Pen is an indispensable multi-functional tool suitable for electricians, technicians, and DIY enthusiasts. It provides a safe and efficient method for preliminary electrical checks and component testing. Its main design eliminates physical contact with live terminals, significantly improving user safety.
Main Functions and Specifications:
Non-Contact Voltage Detection (NCV):
Principle: Detects the alternating electric field around a live AC conductor.
Application: Ideal for verifying the liveness of wires, cables, sockets, or circuit breakers before starting work.
Alarm System: When liveness is detected, a red LED indicator lights up and an audible beep sounds. The beeping frequency typically increases with increasing electric field strength.
LED Component Testing:
Function: Provides a safe low-voltage DC current to the LED component to verify its function and identify its anode (positive) and cathode (negative) pins.
Method: If the LED is functioning correctly and the polarity is connected correctly, the internal circuitry will illuminate the LED.
Safety Standards: Designed to comply with relevant electrical safety standards for handheld testing tools.
B. Voltage Alarm Tester with Multi-Function LED Indicators
Product Overview:
This tester is a compact, professional-grade instrument suitable for basic electrical troubleshooting. It not only performs simple tests but also provides visual feedback on the presence of voltage; advanced models can also display relative voltage values.
Main Functions and Specifications:
Voltage Alarm:
Detection: Identifies the presence of AC voltage via a sensor probe.
Dual Indication: A highly visible LED indicator illuminates simultaneously, while a built-in buzzer sounds, ensuring the alarm is noticeable in noisy and well-lit environments.
LED Voltage Indicator (available on some models):
Function: Multiple built-in LEDs illuminate sequentially to indicate the relative intensity of the detected voltage field, helping to distinguish different voltage sources.
Continuity Test Function:
Purpose: Used to check whether a circuit is closed (closed) or open (open). A buzzer typically sounds when the circuit is closed.
