Multifunction testers are essential if you are installing electrical circuits and completing test certificates. But what tester to buy, what functions should you look for. Why can’t multi-meters be used. Why is there such a difference in price between the models of meters available. What functions are essential, what are the must have tests and which one’s make life a little easier or are just nice to have.
At LEARNELECTRICS we have been asked many, many questions on this subject and here we have put together a collection of answers that we hope will help. From the basic functions to calibration certificates, from how much they cost to deciding between new and used. There are some bargains to had in the second hand market and we point out the important criteria to apply when considering second hand meters. A short but useful video for all.
