- In this video I demonstrate how to calibrate the LCR T4 Mega328 meter for capacitance measurement. The meter measures several components including transistors, resistors capacitors and inductors.
Thank you for talking through this rather than just adding obnoxious music!
You are welcome. I don't care for silent videos when they are supposed to be instructional. I hope that you will subscribe.
Working batteries don't get recognized from this device but a dead one shows up as a diode.
Interesting observation. I did not investigate that as the only purpose of the video was to show the calibration for capacitance. Thanks for the comment.
Thank you for sharing,this is Mohamed from Egypt,i just bought one today,is it possible to use rechargeable lithium battery with thus device as the Tc1 uses one
Hello Mohamed, welcome.
As long as you are supplying the device with 9 volts DC it should not make any difference. Thank you for watching.
@@SurfDetector ok what about supplying the device with a 9 volts wall adapter .you know these adapters where you can control the voltage
Great video thank you! Very useful. How did you know how to do the calibration? I am trying to test N channel (BF245) and JFET (J201 etc.) transistors and need to understand the readout. Can you help please? Best wishes ; )
Hello and thanks for watching. I did the initial video at the request of one of my subscribers who sent me a translated instruction. What is it that you do not understand regarding the readout?
I bought one several years ago and used it a bunch and didn’t use it for a few years and the battery was dead. When I put in a new battery it was displaying something like “not connected/bad component“ and won’t read anything. I did the three pin calibration and I was able to reset the unit and use it again.
That is good to hear. I am happy that this helped you.
Explain to me how to calibrate more and which capacitor you used. Thank you
Hello Ahmad,
I used a 150nF film capacitor. All of the steps are included in my video. The calibration is only for capacitance.

Thank you Engineer🌹🌹🌹🌹🌹🌹
there is a pdf manual duckduckgo.com/?q=LCR-T4+manual
LCR-T4 Component Tester
The LCT-T4 measures components, including resistors, potentiometers, inductors, capacitors, diodes, dual diodes,transistors (including MOS), SCR's, regulators, LED's, and ESR.For testing operationplug the component that you want to test into pins 1, 2 or 3 on either side of the DIL socket,then press the test button.
Specifications:
Resistor: ≤2100Ω
Resolution of Resistance Measurement: 0.1 Ohm
The Highest Measured Value: 50M ohms
Provided Testing Current: Approx. 6mA
Capacitor: 25pF-100000uF
Inductance: 0.01mH -20H
Working power: DC-9V (9 Volt)
hi thanks for the video can you upload a video how to test esr of caps in circuit? there are some Russian video that program this LCR meter to find bad caps
Hello and welcome to my channel. Thank you for subscribing. I do not own a LCR meter as I have never seen the need for one in what I do. I think that the capacitance range on them is somewhat limited. Here is a good site that describes for you exactly how to use one:
www.yamanelectronics.com/test-capacitor-without-desoldering/
The tester displays ESR if the capacitance is more than 2 microfarads. It is unable to measure ESR for small capacitors.
Thank you for sharing this with us.
My pleasure. I hope that it was useful to you.
Hi, I did that on my exact same tester bought a few days ago, and nothing actually happens when I short the three posts together….
many thanks to you ❤
You are welcome
thanks
You're welcome. Thank you for watching.
Anyone else seeing reverse transistor pin designation? I have placed a 2N2222 in the tester, but when the test is complete, LCRT4 shows reverse E.B.C designation. I was expecting to see 1(C).2(B).3(E), but seeing 1(E).2(B).3(C)!
The pin configuration for a 2N222a from CDIL is
1. E
2. B
3. C
Thank's 😊
I am glad that you found the video useful.
Do we always calibrate that tester again and again ? I thought it will only need to calibrate once, then all kinds of components can be tested in just one calibration. By the way, the calibration of each component is different, am I right?
This is ONLY for capacitors and should only need to be done once unless you suspect incorrect readings
Is that normal that i some time to time especially when turned on witch cap installed it shows ESR = 0 Ohm and test need to be repeated few times before it show the result, or mine is damaged ?
Are you discharging the capacitor before you test it? You must not test a capacitor if it has a charge.
I am going to buy one from China.
Welcome to my channel, I hope that you will subscribe.
@@SurfDetector Done！😁
Thank you my friend. I have more videos on the way.
This was the only video I'd seen on calibrating this tester. In what way did any calibration, or adjustment, take place? Is there only a calibration test for capacitors?
The device is being reset to the known value of the capacitor. Obviously the chosen capacitor needs to be one of quality as its value is what the calibration is based on. This process is fairly standard for a test device. The surprising part is that the LCR T4 has the code to do the calibration at all, given the low price.
Which version of the firmware is on your tester?
I am not sure, I have never needed to upgrade it.
I did the calibration according to your procedure, since the battery was not new under 8 v, it turned off in the middle of the calibration, mtester did not want to turn on again. I put a brand new battery, started the procedure and did the calibration to the end.Thanks for the clip.
