We have had a look at the basic techniques to use when having to fault find a circuit. The next topic that should be added to this is the need for us to have a good understanding of PLC’s With the way things have changed, you will come across a PLC in just about every …
In our previous post on instrumentation, we looked at the analogue signal to and from instruments. What we need to do now is to have a look at how you would perform the Factory Acceptance Testing of these instruments you have installed Before we go on, just a reminder to those who have not looked …
Hi everyone, time for a new post again and this time round we will have a quick look at instruments that will give you an analogue signal. Just before we get into that, a reminder to have a look at the Manual for Electricians Volume 1. This is a compact softcover book that you will …

As promised in the last post, we will spend a bit of time on the Instrumentation side and maybe it is a good idea to start with the basics of what you are bound to encounter. First we will look at the different signals you will be getting from these units as this will determine …
Time for another monthly newsletter. This time round we will take a look at some instrumentation devices and we will start with the Electro Magnetic Flow Meter. But just before we get into that, some great news! You can now get your hands on the Manual for Electricians Volume 1 where you will find …
In our last post we touched on a basic technique for finding faults on an Electrical Installation. This week we will continue with another example, but before we do, some great news. The Manual for Electricians Volume 1 is now available. Inside you will find a variety of topics all put together in a book …
