KT4H 0-330V LED TV Backlight Tester with Auto Voltage - Portable and Convenient Tool for TV Repair
from £38.95
The KT4H LED TV Backlight Tester is a portable and convenient tool for testing LED backlit TVs and computers. It can handle loads up to 330V, making it compatible with most TV models. The KT4H can help you easily spot faulty LEDs, saving you time and money on repairs.
These can also be used to diagnose faulty LED modules used on modern cars making them ideal for Car service technicians as well.
Features:
Suitable for use with most TV's, Monitors or Laptop displays that utilise LED backlighting.
Real-time testing voltage and constant current drive board.
Test LED strips, LED panels, single LED bead, COB lighting sources and so on.
Test backlights of LED TV, displays, computers and so on.
Compatible with all the LED strips (high voltage or low voltage).
Manually adjustable testing voltage range (20-330V/DC) and current (20-150mA).
Adjustable voltage at open circuit (without loads) and adjusting current with loads or contact probes together.
No burn out when testing single LED bead with wrong polarity. (Set voltage around to 20V and the current switch to 1mA)
Test voltage parameters of various of electronic components.
Test LED lights on vehicles.
Specifications:
Suitable for use with most TV's, Monitors or Laptop displays that utilise LED backlighting.
Product model: KT4H
Voltage input: AC 85-265V
Voltage output: DC 0-330V (Automatic + Adjustable)
Voltmeter Accuracy: < (± 0.5 ± 1%Vout) V
Amperage output: 0-150mA (Automatic + Adjustable)
Constant Current Board Testing Current: 0-999mA
Ammeter Accuracy: <(±2 ±1%Iout) mA
Pinput: 50VA (MAX)
Operating Temperature Range: -20℃~+40℃
Package contains: 1x KT4H Tester, 1x Mains Lead, 1x Constant Current Cable, 1x Constant Current Clip Cable, 1x Pair 20A Test Probes, User Manual
Testing Methods:
Default factory setting: Output Voltage 330V, Output Current 30mA. You can testing the backlight of TV with any size at this default settings.
Self-testing: Plug in, turn the power switch on. The voltage is around 330V, current is 0; Contact the probes together, voltage changes to 0 and current changes to around 50mA, then testing can be started
In testing: Voltage = ‘0’, SHORT CIRCUIT. Voltage = ‘330V’, OPEN CIRCUIT.
Testing single LED bead (Set voltage around to 20V and the current switch to 1mA):A. With right polarity: the voltage shows on the tester of a normal LED bead is about 80% of the rated voltage, for example, the operating voltage of the LED bead is 2.4V if its rated voltage is 3V;B. With wrong polarity: Voltage display the open circuit voltage.
Testing LED strips: Set the voltage to around 200V, change the current if need adjust brightness.

LCR-TC1 Colour Screen Multifunctional Transistor Tester: For Diode, Triode, Capacitor, Resistor, LCR, ESR, NPN, PNP, MOSFET
£17.95
The DANIU LCR-TC1 is a versatile and easy-to-use component tester that is perfect for electrical repair technicians and hobbyists. It features a clear and easy-to-read colour screen, making it easy to quickly test a wide range of components for values and failures. The 14 pin ZIF socket allows for quick, easy, and hassle-free testing. Simply pop your component in and close the handle, and the unit will test the part and provide feedback on its results.
The DANIU LCR-TC1 is also equipped with an IR sensor that can be used to diagnose infrared remote controls. Simply point the remote control at the tester and press a button to see if it responds.
Features:
Detects NPN and PNP transistors, capacitors, resistors, diodes, triodes, N-channel and P-channel MOSFETs, IGBTs, JFETs, Triacs, and batteries
Detects infrared wave forms
Can detect Zener diodes and has a self-calibration function
For IR detection, align the infrared remote control with the "IR" light, then press the button in the remote control, if the detector successfully decodes it, it will display the data code and infrared wave form.
Easy to use with one-button operation
Put the pins of component in corresponding area, then close the handle and the detector will test it automatically
14 pin ZIF socket for quick and easy testing
Colour screen for clear and easy readings
