New ANENG Q1 9999 Counts ?
adynis:
I am also curious what triggered the issue ....
I measured some 230V AC current. And I remember I also pressed the Range button, and it jumped to Manual mode ... , and then ... I don't remember, but .. while having the cables connected to the AC device, I might have turned the multimetre off and again on, to change it back from Manual to Auto ( although I'm not 100% sure if I really did this ....). My AC measurements went fine ... only the next day I observed that the DC was not working anymore ...

I have had this meter for a while now and have nothing but good things to say about it. Banggood´s shipping not so much. Seems someone played football with the meter before shipping and packed a dirty dusty and cracked meter in my box and shipped it. Not even brushing the dirt off the storage bag. Since the plastic over the LCD had a crack I got the money refunded and got to keep the meter for free. I had originally paid 28 Euros shipped for it but now that it is free it is even better.
They updated the LCD to a brighter model at some point and it seems I got the newer model so I have no comparison. I have seen that the printing around the Amp plugs is different on some meters which seems to determine which version you have. According to some posts online the format (decimal placement or something) for the amp readings was weird on the first model but I have not noticed anything which also leads me to believe I have the newer version.
I really like the meter. In my opinion the screen is bright and easy to read even when the sun shines through my windows. The batteries it came with have lasted over 3 months of using it 10-25 minutes a day. I also used the batteries in a camera flash a few times which uses a ton of power so it does seem to have a decent battery life. I haven´t noticed any calibration issues and the only thing that bugs me is that it automatically turns on in auto shut off mode which is quite short. Yes it is easy to turn on without the auto off but I always forget to do that until it starts to beep.
People online have done mods to change the backlight / text color of the lcd, add a lipo rechargeable battery, and add a LED flashlight (a mod I will be doing soon). So it is easy to mod new features into it which is cool and I want to try adding a esp32 or some kind of wifi mod.

I have the same issue. When i so connect my COM probe to the gate of Q4 it switches to volt as long as i keep the probe there. Would this not indicate that there is constant current to the gate, which fails to break by the relaid/solsnoid?
If that is logical then the fault is in the solenoid.

Another succesful repair based on @indman advice - thank you very much!
I my case, I'm 100% sure the transistor was blown while I was doing some AC current measurements (from a 12V wall wart transformer), so there is a common thread here, and a million billion % sure I did not just short the source with the mutlimeter... which probably means I did. The fuse was blown in either case. Thanks to this advice, I was able to easily verify Q4 was blown (shorts across all terminals), and replacing it fixed the problem.
By the way, I can confirm that uA/mA ranges on the newer version are different. On the mA/uA socket you now get 99.99 mA (I guess that's a proper mA range) and 9999 uA. Older version had (I think?) 999.9 uA and 99.99 uA instead, so it's a weird tradeoff (less accuracy for a proper mA range). Haven't seen much info on how good the <1uA accuracy actually was, so maybe not much tradeoff actually.

Hello everyone!
My Aneng Q1 was unused for some time, after that, it just selects the functions and incorrect reading in the DC and AC scale.
For example:
12V DC my Aneng reads 15V DC.
110V AC my Aneng reads 128V AC
It does not read Capacitor, Diode, Continuity, Resistance, Frequency and Duty Cycle.
Could anyone give me a hint where to start??
Thanks!!!
