New LIDL multimeter on the way.

[Fungus]

Just got this puppy. Jesus, it is huge. For some reason I expected it to be small, like aneg 8002.

I got mine last week. Haven't had time to open it yet...

okay, I'll film a tear down today... But don't expect too much, I bought it to use, so no destructive testing, I'm not Joe Smith .

Here it is: https://youtu.be/9wQdiaUCHu4?t=394 . You can safely switch sound off, I was mostly talking to myself.

Basically as expected. I assume the fuses are marked 300V instead of the usually 250V.
I will neither call it bad or good, it is a cheap meter and with the fairly low CAT rating it passes the tests.
With only a single chip and no EEPROM or trim pots it looks like a fairly new design and will probably be true rms (I have reviewed a couple of meters like that).

I thought the cheap meters in fluke 10x class didn’t bother with true RMS. Even the low end Gossens don’t have true RMS.

I thought the cheap meters in fluke 10x class didn’t bother with true RMS. Even the low end Gossens don’t have true RMS.

That changed with the DT0660 chip, a cheap DMM chip with build in RMS and a external EEPROM with calibration and operating modes in it. Since then another cheap chip has arrived without external EEPROM, also with true RMS.

This one is RMS of sine wave - see full specs in manual. (Link earlier in thread.)

I hooked it to my siggen (singlent 2042x unlocked to full potential, calibrated at factory ~3years ago), here is what I have.

Sine wave: 1Vpp
0.354V@100Hz
0.354V@1kHz
3db point (amplitude 0.247) is at 4.2kHz
0.19V@10kHz

Square wave 1Vpp, 50% duty:
0.504V@10Hz
0.552V@100Hz
0.508V@1kHz
0.461V@2kHz
0.411V@3kHz
0.332V@4kHz

PS checked fuses, they are rated for 300V, which is good.

When I check meters to 95% reading most cheap meters can go up to 2kHz to 3kHz. Your results looks very similar to that.

There's also a nice video done by Asser's Lab who went from there and wrote a Python version for the Raspberry Pi:

ETL tested to UL standard??

I just noticed that Lidl have a couple of meters coming up on Easter Monday. Both look aimed more at the electrical market. One is a pen type and the other a clamp meter (AC current only). They've upped the odds on these two with Cat III 600V ratings, both are GS marked and TUV certified so there's good reason to believe these. Not bad for £12.99 UK.

The pen meter certainly looks the part, with tool accessible batteries, decent finger guard and GS38 shrouded probes. With the enhanced ratings, it might make a useful partner for a average low Cat rated DMM for mains / higher voltage use.

The clamp meter probably fairs badly against the UT210E as it only has AC clamp ranges, but there again, it does have a 600A range without EEPROM mods and is half the price.

There's a very brief teardown of the pen multimeter in the YouTube video below - 13 mins in.  Melf attenuator resistors, Fusible through hole resistor, single PTC and plenty of clamp diodes in evidence. I'm not keen on having shared sockets for the uA and mA ranges on a Cat III meter, but at least it does have a proper 250mA 600V ceramic fuse. At least there are no higher Amps ranges, which ought to reduce the drama of accidental current range selection. The IC is glob top.




P.S. They have their 20V 2Ah and 4Ah batteries in again on the same day, together with a spare charger sold separately for once (it's usually bundled with a 2Ah battery).

PS checked fuses, they are rated for 300V, which is good.

From microcontroller.net picture it seems these have 5HF 300V marking which indicates it might be: Holly 5HF
If so, these are IEC60127 compliant. Link to LCSC 10A version (250mA not available currently). These are not standard ratings, interchangeable or available from other manufacturers, typically such fuses are rated just for 250VAC, not for 600VAC and 450VDC as in this case.

If I can find one I'll try to buy two, with an eye of shipping one to Joe Smith.

It's about the same money as my last 8060A catch
