Assembly hints 1. Assembly (Skipping this can lead to troubles ! ) Ok, so we have your attention. These hints will help you to make this project successful. Read them carefully. 1.1 Make sure you have the right tools:  A good quality soldering iron (25-40W) with a small tip.  Wipe it often on a wet sponge or cloth, to keep it clean; then apply solder to the tip, to give it a wet look. This is called ‘thinning’ and will protect the tip, and enables you to make good connections.

Connection & test 11. Connection & test The push button (single pole normally open contact) has to be connected to the points PB. Display selection is done by connecting VD1 respectively VD2 to VD. You can make these connections permanent, or use a bipolar three position slide switch as shown in the connections diagram. In this case the slide switch functions as selector and on/off- switch at the same time. The power supply has to be connected to the points + and -.
