Digital Meters For Educational Institutes INTRODUCTION Today we want to provide the best Technical Facilities and Equipments in Educational Labs, so that students can have hands on experience of latest technologies and products used in Industrial Environment . Let’s take a case of an Electrical Engineering Lab. There we have to do many experiments related to verification of particular law or theorem, estimation of motor’s & transformer’s parameters or designing a new system .Here we need to first measure various electrical parameters like Wattage ,Current , Power Factor etc. And then we do the calculation using standard formulaes ,plot the graph and arrives on the conclusion . We have designed and developed Digital Portable Meters for conducting experiments in Educational Institutes , that will not only make the work more accurate and reliable but simpler also. Traditionally we are using Analog meters in our Labs. Let us have a look at the various advantages of the Digital meters over the Analog meters. Advantages of Digital meters over Analog meters Accurate & Reliable. Faster Response. Better Readability . Higher Resolution. There is no observational error such as Parallax and Estimation. In case experiment requires multiple parameters , we can replace many meters with just a single Multifunction meter ,that will reduces the unnecessary and repetitive wiring , thus saves lot of time and energy . Computer interfacing can be provided for data analysis and recording . Last but not the least ,they are economical .
