New LCR meters, Zoyi ZT-DQ01 and ZT-DQ02 (March 2025)

[tunk]

Could look like v106 for ZT-DQ02 is here: http://www.szzotek.com/h-col-159.html

[RAPo]

I'm on V1.05

Maybe firmware 107 ? https://www-mydigit-cn.translate.goog/thread-515071-1-1.html?_x_tr_sl=auto&_x_tr_tl=sk&_x_tr_hl=sk

Do you have invitation codes for that forum? Seems you can only sign up from invite from existing members.

I don't have one, but that wasn't the purpose of the post. Just information that something is probably being worked on. Also, let the local guys try it out before it gets to us
 i have fw105

From a Chinese forum
This bridge does not have a DCR 0Hz setting. Customer service said it might be updated later.

I'm curious.

[RAPo]

I've upgraded to V1.06. Don't see much difference.

I'm on V1.05

[Atlan]

There are a lot of bugs to fix. We'll see if most of them can be fixed by the time V110 is released, Chinese people say.

My Zoyi DQ01. Big part of the board is not populated. There is no match for $42... 

[Serg65536]

INA826 differential instrumentation low power op amp. Is it good for 100kHz? Probably just barely enough...
What is 49 p113 ti chip?
tc4056 for charger.

[Serg65536]

MS8606 is low voltage dual general op amp 10MHz BW.

[coromonadalix]

updated to 1.0.6  can't see any differences ?   nice idea  to just drop a file in it when in usb boot

it create a drive in windows explorer, drop it in,  and voila ...   

[andre3d]

p113 is PGA113AID -Zero-Drift Programmable Gain Amplifier With Mux

Similar scheme LCR Tweezers Bridge Tester see attachment

[coromonadalix]

have you seen this one  loll

I also bought the ZT-DQ02 model with all the cables on Ali. It will arrive on April 25, let's see what kind of beast it is. At work I have a Hantek 1833C and an FNIRSI HRM-10, I'll compare how the ZT-DQ02 batteries measure, I also have an ET433, I'll see who's more flashy )) oh, the latter are expensive for me... 

The ZT-DQ02 cost me $78.96

[mawyatt]

I did a short test of the battery tester, both before and after calibration, and the Fnirsi HRM-10 is more accurate.
Still, a nice function to have.

How much of a difference did you experience?

Have you or anyone done an actual comparison of known R and C components with another reference LCR meter(s)?

BTW does the Battery Test Function have better resolution in the R measurement than the LCR Function? Seems this is 0.1mΩ vs 1mΩ from the manual images.

Best

I´m planning to make a test report this weekend, using DMM check plus, the DQ02 and uni-T and hantek lcr meters.

I did a short test of the battery tester, both before and after calibration, and the Fnirsi HRM-10 is more accurate.
Still, a nice function to have.

i Found review from china

I recive ZT-DQ2 and make little test/ Firmware 1.05
REC and REL mode do not work i press and hold this buttons but i do not see changes
button REL% work only with active resistor... with capacitors do not work

Battery celvin clips do not compatiable with gx connectors, used in  YR1030 YR1035 RC3563
in user manual written about SCPI commands... but do not info about SCPI command list or software

For calibraion need many precission resistors 

[DaneLaw]

Battery celvin clips do not compatiable with gx connectors, used in  YR1030 YR1035 RC3563

They are not using the same connector.
As I speculated earlier in this thread. [#15] on the standard used in YR1035.
While YR1030 is using USB-A, while RC3563 (if I recall correctly) are using GX16-4p

So, what model of Kelvin clips did you try with?
Obviously not YR1030, as that one is based on a USB-A-socket (same as DC-YR2050, as I'm cycling Kelvin-clips between those two models)
While the one I speculated could be used was YR1035, and perhaps without any modifications if the pinout matches.

YR1035 =

RC3563 =

YR1030 =

I've emailed Zoyi about the scpi interface. Snarkol was very responsive but did not know the answer. Hopefully Zoyi will respond. I used the supplied probes of each device. Indeed connectors cannot be interchanged.
If you long press the rec mode a com-port will popup in win-11, but also an unknown decide driver message. It would be great if it was an Hid device just like the GW Instek LCR-1100.

annnd  the prices has began to slowly rise  from the same seller and others .... but they give an 10$ off   loll


@Rapo,  as soon it is powered and USB-C connected,   you have a com port appearing ?? no drivers needed

in flash mode  it's an other kind of device who appears

AND for me,   better focus on FW stability and functions than implementing scpi commands  unless you do binning logging binning production related stuff ...

[RAPo]

When I long-press on HOLD/REC, the com-port appears as described in the manual on page 12.
The com-port is a usual USB-serial device. No drivers needed.

but you don't need to hold anything when you connect    

on mine DQ02    v1.05 or now v1.06   as soon it is powered up,   it connect into windows automatically if your Usb-C cable has data wires in it

x/d/q /0  ESR is for the FW upgrade ?? 

Sorry  i'm not following  ... what do you intend to do when usb connected,  if it is not charging ??    poke in the lcr firmware ?

[ass20]

board have swd connector  itis pin out

uart tx PA9/SWCLK/GND/SWDIO/3.3V
for connect  to cpu need remove battery and use 3.3v from jlink , daplink
Need connextor with 2.0mm step (NOT 2.54)

CPU is locked
ArteryICPProgrammer said the cpu is at32f403Z (tqfp144) but real cpu is tqfp100 package... used custom cpu ?
On reference manual for at32f403 written DEBUG device ID (DEBUG_IDCODE) is 0xE0042000

The DEBUG_IDCODE register is
mapped on the external PPB bus at address 0xE0042000. This code is accessible by the JTAG debug
port or SW debug port or by the user code
But i cannot read this adress

[RAPo]

Read page 12 from the manual: You can automate measurement by sending SCPI codes.
So you can write a program that iterates over eg the levels and frequency, and save the results to a file.
but to get that working you need to get in the USB-Com port (or maybe USb-HID device).

Like Rudi does on his newly bought GW-instek:

[coromonadalix]

from Artery you have many softwares, bootloaders isp  etc ...

and maybe unpack the firmware like they try on  the Zoyi handheld 703 scope ??

sure scpi would be nice to have ...  but this lcr is not for production purposes ?  and they claim 100mF / 100,000uf   loll  alas no capacitor to test that affirmation loll

[ass20]

I do not know why main chip (tqfp100) mark is clean but other chips is not clean...

May be is not artery chip ? or artery chip clone ? I connect to chip whith artery tool... and it said at32f403Z chip (Z is qfp144) ...

scpi command may be found in FW update file v1.06

Any body have fw update file with vwrsion 1.05 . please upload

what softawe may be use for test scpi commands ? without labView etc..
