Amp probe meters are very easy to use, and you do not need to be an electrician in order to use one correctly. Depending on the type of current and wire you are testing, you will need to set the amp probe to a 0-10 or 0-20 amp scale. A local electrician could advise you about setting your amp probe meter.
However, the basis for an alkaline diet encompasses many healthy eating habits, so it can be a healthy diet change. Cutting out acid-forming foods means cutting out processed foods, like sugars and refined carbs. To increase your alkalinity, add alkaline foods to your diet, such as green vegetables, root vegetables, and almonds. Avoid acid foods, like meat, dairy, and sugar. You should also drink plenty of water and exercise.
But you DO want to shift the overall balance of your diet over toward the alkaline, and away from the excessively acid-forming diet of a quick-food culture. Free range eggs, fish, beans, unsaturated oils - these are healthy foods, low glycemic and nutritious, and even if marginally acid-forming (or alkaline or between the two depending on how you measure or what chart you read).
