Compact and Versatile Automotive Tool

Essential tool for any automotive DIYers out there! As a result of using this multifunctional portable tool, I found that it drastically simplified my garage setup. Its wide range of features and compact design makes it perfect for diagnosing and repairing any issues ranging from simple electrical problems to more complex engine-related matters. Additionally, the device is highly programmable and easy-to-use, with customizable settings to suit a variety of needs. However, the only downside I…

Pros

Cons
  • Takes some time to figure out the setup

NO instructions. Good for power accessories

This programmable multi-relay board came with no instructions. I mean NONE. How the hell am I supposed to know how to program this thing? Having to go back online to track this is one hell of a bad sales skill. Customer service has gone wrong across the spectrum (only the latest I've bought from many with similar issues).

Pros
  • Electronics
Cons
  • Poorly designed

Works as expected

I recently bought one with one channel and it was pretty easy to use. see instructions but hold "set" to enter modes.md - your mode is blinking (here select channel 1 or 2 and function) t1 is timer 1t2 is timer 2 off/on or something similar) Nx is the multiplier for your timer, I think 0.01 is the baseline. So if you go by seconds, set that to 0100

Pros
  • Current Transformer
Cons
  • Minor issues
