    Well packaged, received in good condition and very fast delivery time (7 calendar days from order).

    I use a lot of these, both in the two-wire and 3-wire versions. The 3-wire version uses a separate measurement wire and allows a larger measurement range.

      Q: What colour does it display R, B, G, W?
      A:
      These are available in red, green and blue. I have bought each version at different times over the past 2 or 3 years. As per the listing, this set is RED. If you'd like green or blue, I'd suggest waiting; they will probably be available when the next batch is stocked.

      Q: In 3 wire mode which wire is common (black?), which wire is test input with a range of 0 to 100V (red?) and which wire is power supply with a range of 0 to 30V (Yellow?)
      A:
      If detecting a 100V power supply, the red wire is connected to the positive electrode of the working power source, and the black wire is connected to the negative electrode of the working power source. The yellow wire is connected to the positive pole of the power supply under test, and the black wire is connected to the negative pole. If the detection is below 30V and there is only one power supply, the red wire and the yellow wire can be connected in parallel to the positive pole, and the black wire to the negative pole.
