mikey553 1/32off? Are you kidding me? You can use a rule or tape measure if this is the accuracy you need.

Outer diameter were as close as I needed it to be. No more tha 1/32 off. The inner diameter gave me similar results.

mikey553 Itis a plastic caliper and it cannot be accurate. You have to be very poor to justify buying this tool. A stainless steel caliper costs only slightly more, but it would be a real measuring device, not a toy.

Its not the best caliper but very high quality for this price. Accuracy is not bad. It came with 1+1 batteries. Came just in 1 one week to Turkey. Fast shipping. Fena bi kumpas değil ama en iyisi olduğu söylenemez. Hassasiyeti çok iyi değil ama iş görür. Üstünde bir tane takılı bir tane de yedek pille geliyor. İstanbula bir haftada geldi. Gövdesi plastik ama öyle aşırı kötü bi

mikey553 Yousound like you know electronics. Can you clarify your modifications? There are five 1k resistors on a small board, but the components are not marked on the board. Which one of the resistors needs to be replaced with 470 ohm? Also there is only one component on a small board looking like a diod, it is marked M7. Is it what you had in mind? I do not see M

Great tool, but needs 2 quick modifications to be reliable long term. Firstly, on the small board with the OLED screen, the 1k resistor marked R4 needs to be replaced with 470 Ohm, this is to increase MOSFET gate drive, and ensure a faster, harder on state, making the FETs go into saturation quickly and avoid overheating/frying. Also, the M& diode on the positive input leading to the massive 10,000uF
