As the name suggests, multimeters are those measuring instruments which can be used to calculate multiple circuit characteristics. Making them digital gives highly precise outputs as unlike their analog counterparts, there is no needle whose pointer is to be figured out. Multimeters are into electronic measurement purposes since long and are expected to stay for long and get more modifications of measuring quantities. Analog multimeters were initially in trend but required calibration and human error often caused errors in measurements. With digital measurements, results are not only more accurate but can also be resolved to a high level.

Insight – How electrical Line Tester screwdriver works
Testers are one of the simplest solutions, used to test current and voltage continuity in any circuit. Indispensible for any electrician, the testers are very simple and interesting devices. This article will explore the internal structure of one such commonly used circuit tester.The user is required to be on the floor while using the tester so that he can serve as ground when current flows. In order to test the live wire, the user’s body must be in contact with the metal cap on the top of the screwdriver when the tester is put in contact with the wire. This completes a genuine electrical circuit and the bulb will light up once the tester senses voltage.
Load Cell
Day-in and day-out we have been using electronic scales or weighing machines. You go to any grocery store or a jewellery shop; the items are weighed using electronic weighing machines (Weighing balances are also used in situations where very high accuracy is not of paramount importance). But, have we ever given a thought on the mechanism of the electronic scales? At the heart of electronic scales or weighing machines is a sensor called load cell. These sensors sense the force (or weight) of the items and the electronic circuitry processes the sensors’ output and displays it on the indicator. Load cells are highly accurate transducers which provide the user with information not generally obtainable by other technology due to commercial factors. Usage of load cell is not limited to electronics scales; they are used load testing machines, industrial scales, flow-meters, etc., though we hardly ever come in direct contact with the load cells.
