Geekcreit® LCR-T4 Electronic components tester – MUST HAVE !!

October 12, 2019

This is Geekcreit® LCR-T4 KIT It’s a all in one electronic components tester There is a LCD to show information and a universal socket for components I buy version with acrylic box Hand strap ?? great !! First I will take off protection foil from acrylic They missed one peace in hole 😀 There is no instruction so I need to think how to assembly it I don’t know what this hole do Let Me check on internet pictures 😀 Hole on left is for lever and on right bottom is for hand strap Longer supports go on bottom Nuts go on bottom and supports go on top In this moment I need to put battery and test it No, it will not “Blow” 😀 Tester have automatic off Also put hand strap in this moment And ready 🙂 Look great !! First I will test some resistors 750 Ohm From left test pins are 1 2 3 1 1 1 1 Detected that it’s a resistor and measured 749. Ohm Now 160 Ohm I can use any of number 1 pin with 2 or 3 pin 157,9 out of 160 Ohm I don’t have certificated tester so i can’t confirm parameters 100k resistor 95.25 kOhm Now 104 100nF capacitor 85.38 nF and also show vloss (what ever is that 😀 ) 1000 uF capacitor Also show ESR What about polarity if I rotate it ?? No change, still test it 🙂 Now diode Yes, that worked also 🙂 It’s also showing direction 🙂 5v stabilistor Nope !!, it’s the only component that this device could not read 🙂 PNP transistor yes and also show where is Emitter, Base and Collector 🙂 Can also test NPN 🙂 Now inductors No problem 🙂 What about a LED diode ?? No problem but can’t detect max voltage You can see how device send test impuls For this money it’s My favorit test tool !! Look how many component’s You can test Here how strap is mounted Working with electronic ?? GET THIS DEVICE !! It’s also great for kids 🙂
