content: What's new compared to MD1:- Upper frequency limit: 100kHz (good for low inductance and capacitance)- Frequency scan mode (table of the primary and two secondary parameters on 100, 120, 1k, 10k and 100kHz)- Pass/Fail mode- Voltage measurement <30V- Measurement data transfer and control over the USB-C port through windows software- Measurements log file on the device itself- Waveform Generator (6 types: 10kHz, and sine: 100kHz)- Aluminium case- Calibration board (optional, with small smd resistors 0, 1, 10 , 100, 1k, 10k, 100k, 1M, 10MOhms)- 4 Buttons- Automatic display orientation rotationWhat's the same:- LCR bridge Tweezers measuring Resistance, Inductance, Capacitance, Diodes (with continuity)- Auto component recognition- 0.1V, 0.3V, 0.6V (0.1V is available on the old MD1 with firmware V2.0)Now price is about 32$, but I've ordered for 24$ with the calibration board as an early bird deal on AliExpress.PS: I'm not a huge fan of Zoyi/Zotek, but this device should be very good in terms of price/performance ratio.

content: Are anybody interested in review on this thing?I have a bunch of precision resistors, DQ01, MD1, XJW01, voltage sources...

content: Quote from: Serg65536 on September 18, 2025, 07:04:18 pmYes, please. I have an MD1, which I'm generally satisfied with, but it would be nice to see those new features like a scan measurement and voltage. Comparison with the MD1, DQ01, voltage and resistance references would be very interesting.It's a pity that they haven't implemented a 4-wire measurement as an option (like the new tweezers from Fnirsi).

content: Quote from: ychat on September 19, 2025, 10:57:55 amI have an idea to try 4 wire Kelvin aligator clips on MD1. It's 4-wire untill the vry tips.Or, as an alternative, cut and solder 4 needles to each bridge contact. This should solve the issue with fluctuating impedances close to zero.

Maybe not everything has been sorted out with the EU yet.https://www.aliexpress.com/item/1005009944321989.htmlhttps://www.aliexpress.com/item/1005009963879146.htmlhttps://www.aliexpress.com/item/1005010032167106.htmletc.

content: I shielded the analog measurement section of the circuit with copper foil, including the terminals. Now, connecting to a PC via USB completely eliminates interference in measurements, and you can use the Zoyi software without worrying about distortion from the battery charging system.

content: As it turns out the HW of Zoyi MD2 (as well as Snakol SK-BD2) is identical to QPLink S1 tweezers that were available from AliExpress a few months ago but was discontinued. Moreover, it is possible to install Zoyi MD2 FW on QPLink S1 and enjoy all the new features.
