Are you confused how to monitor AC (Alternating Current) with digital panel meter or any digital multitester for that matter? Well, monitoring or watching mains AC current consumption of a particular individual appliance or of the whole house using a digital ammeter/current meter is easy.
The idea may be easy but highly impractical, because the procedure is not safe, tiresome and moreover engaging a costly multitester for the task doesn’t seem to be a feasible procedure. An occasional checking through the above method may be justified but for a all 24*7 monitoring surely a rather better, robust and cheaper system wouldbe advisable..
The proposed idea for monitoring and measuring house mains AC includes a cheap moving coil meter and also a smartcircuit to produce a warning tone in case the current consumption rises above a predetermined level.
This facility becomes especially useful to monitor the current consumption of a remotely situated residence (more suitably a rented one) and make sure that power there is not ill-utilized or overkilled without the permission of the house owner.
The circuit acts quite like a power saver is easy to build and utilizes very little number of components and therefore becomes very economical yet performs the said operations flawlessly.
