I have the same one as your old meter i built it from a kit about 30 yrs ago still use it and it works great. Was in the repair industry through the 80s to early 2000's in Australia.
I've kind of wanted one of these tweezer LCR's for a long time. This looks like a good one in that it measures ESR as well. I also built my own ESR meter over 20 years ago, from a DIY design that uses an analog meter. It works well, and I think I've changed the battery in it once since I built it! That said, for $34, these things look hard to pass up - I found the same one on AE for less than BG and with faster shipping too!
Would this be a good tester for high-voltage electrolytic and film capacitors in-circuit? I have a vintage Ikegami tube camera and I want to check the capacitors in the pre-amp circuit for the pickup tube. There's high voltage on the board so many of the caps have a high voltage rating. I would not prefer to desolder them as I don't want to damage any pads on the board since it's a vintage board and even though I'm using a low temp iron sometimes pads will rip on these old boards.
Probably your camera has inside a small rechargeable battery that store the settings and keep the clock running. That battery is not in good shape and you have to use/charge the camera more frequently in order to charge and prevent the date storage loss. Another solution is to replace that battery. Don't confuse this small battery with the main battery that drive the whole camera.
Why are there different frequencies? Shouldn't it be the optimal frequency? Or does it depend on what the capacitor is being used for? Very interesting.
Dielectric absorbtion... Capacitors aren't perfect and at different frequencies they'll have different behavior. That is why you wouldn't use ceramic disc caps for audio or anything linear. or mylar caps for high frequencies.
If it's just being used for line rectification, the ripple will be primarily 120hz. If it's filtering the output of a switching power supply, the ripple it's filtering will be at the switching frequency of the power supply - usually in the 10-30 kHz range. If it's actually being used in a signal path, and not as a power rail filter, the ripple will be whatever the signal is on the line
Holding down one or several buttons might change the language. I ordered several general purpose lcr etc meters. 1 arrived showing Chinese, but holding a button for 5 or 10 seconds changed the language.
@@robertlsvejda I don't think you can change the language on these cheapie 30 ones - I looked at the menu with google translate - there's no language option there. Unless you're really dumb you can figure out the main modes on the main screen in about 15 seconds. Google translate will show you what the 6 or so menu options are - there's nothing in there that's overly exciting.
Zoom in, some kind person might screen translate. I tried from the blurry zoom and got 1"Exit" 2"Calibration Settings" 5"sound settings" second section 1"Export" 2"Save settings"
There are some basic button function instructions on the Banggood website but nothing relating to changing the language. At £38.68 approx $68.71 Canadian i would not call it cheap. Having at last retired from the trade this would just be an expensive toy for me.
@@rickoneill4343 They can keep them at that price, if you are using them for most repairs then that cost can be recovered, but now that i am retired i will make do with what i have It is esy enough to make some tweezers with contacts at the tip to use with any LCR meter.
I had it on my phone a few years ago but it stopped working and told me I need to update my android. Problem is my phone is not being updated anymore. I have a new phone but can't install a few apps I use that are no longer supported. One is bbm. Yes some of us still use that to communicate and haven't switched. Will have to soon though as they are shutting that down in November. Got to find something else thats not Facebook, whatsapp or any of any of the others that are tied to physical phone number.

Same here. Got into the business in 82, got out in 03
I have an OG unit with the tweezers. I think they still make/sell it. (US made) but it's like 250usd. I got mine used from an estate for much less.

It will check in circuit but to get accurate reading one side needs to be isolated. Otherwise stray capatacence will give erroneous readings.
I use google translate on my phone all the time to translate Chinese into the menu. My thermal camera switches all the time to Chinese.

Nice. A lot more hand than my old one. I’ll try it. 🎉

It's called SMD component test pen.

@@alanrussell6678 there are many meters out there that post specs claiming such capacitance range. Most of them go bananas measuring below 100nf.
@@alanrussell6678 Thx for posting specs....impressive device.
Cool device
It works. Used it on the Samsung sv5000 repair.
Industry test frequencies are 100 Khz for SMPS caps. 120 Khz Linear PS caps. So for serious testing ... it missed the mark.
My bob parker checks at 1KHz

Cheaper then the kir meter i built which was over 100 for a plastic box and a bag of parts.
@@12voltvids Possibly, but the instructions were not in Chinese.
And if it breaks you can repair it.
Much cheaper than the other options for tweezer types. I belive the more common ones are upwards of $250

You can find them for $30 on AE - yeah, with the CDN exchange, they'll still be more, but that's pretty cheap

Download a Chinese to English reader on your cell phone and you just point the camera at it and it will translate it for you
