Specification
["Accurate and Reliable: The tester allows for accurate and reliable frequency testing and infrared signal detection of remote control devices. It helps users identify any issues or faults with remote controls.","Detection Range: Effective testing range of this infrared frequency tester is within 5cm, the closer it is to the testing zone, the more accurate the measurement. The frequency of the car key is generally divided into 320M HZ; 434M HZ; 868M HZ.","Easy to Use: Just place the remote control near the tester in the testing zone, press the power button on the remote control, and the tester will display the frequency value, accurately measuring the frequency.","INPUT Indicator: By pressing any button on the remote control, the indicator light will flash red, indicating that the infrared output is functioning properly. If the indicator light does not illuminate, it indicates that there may be a malfunction or damage to the infrared transmitter.","Convenient Lighting: The infrared frequency tester is equipped with LED lights on the front, making it easier to use in low light conditions, ensuring visibility and accuracy during testing.","Application: Applicable to all models of keys and electric door controllers, car burglar alarms and other remote controls, electric locks, garage doors, remote controls, access control, etc. The car key and door controller can be directly tested for frequency. They need to be placed in the TX area to obtain an accurate frequency test result. The TV (IR) remote control cannot test specific frequencies. It can only test whether the buttons of the TV (IR) remote control are functioning properly by observing the LED lights."]
