The electronics industry has been highly dynamic since time immemorial. In the recent times, however, many companies have immersed themselves in the electronics industry. This could be as a result of the recognition of the impressive profits that such a venture holds. One company that has carved a niche for itself in the electronic industry is LG Electronics. This is a global telecommunications and electronics company that has its headquarters in Yeouido, Seoul, South Korea. LG Electronics Corporation carries out its businesses via four different divisions including home entertainment, air conditions and energy solution, mobile communications and home appliances. Testament to its position in the global market is the fact that it is considered as the third largest manufacturer of mobile phones and, the second largest television sets manufacturer in the world. In addition, it is noteworthy that the company is LG Group’s flagship subsidiary company. LG Group is considered one of the largest (if not the largest) electronic conglomerates in the world. It has numerous subsidiaries all over the world that manufacture and design home appliances, telecommunications devices and televisions. Its home entertainment division provides televisions, PDP modules, plasma display panel (PDP) TVs, LCD Televisions and video, audio and storage devices. On its side, the home appliance division comes up with items such as microwave ovens, washing machines, compressors, cleaners, motors and many others. The air conditioning division offers items such as solar cells and air conditioners, while the business solution division offers software, hardware, content, systems and network.

Obviously, the company has made a mark in the telecommunications and electronic industry. It is estimated that, for every four homes in the world, one would be likely to find LG electronics in one of them.

For all these appliances and electronics, there are a number of salient issues including standards, precision, accuracy, reliability and errors. These issues have a crucial impact of the electronics’ performance. Every appliance has standard magnitudes, the fundamental relationships of which determine their quality. Their precision is related to the number of significant figures that are displayed (Brusee, 2004). The appliances with the higher number of significant figures would have a greater precision. In the making of these appliances, certain parameters are set in such a way that their indicated values would be in line with the true values. They would be said to be accurate if the indicated value is in line with the true value of the appliance that is being evaluated (Brusee, 2010).

In some cases, certain aspects of the appliances or electronics would be different from the true values. The applications will be said to have errors. There are variations in the accuracies of the electronics depending on the applications. Either way, the errors are classified into two groups, which are systematic and random. Random errors refer to random fluctuations in the indicated values while systematic errors come by as a result of variations in the performance of instruments. Random errors result from unpredictable and unknown changes in the making of these electronics (Brusee, 2010). The variations may occur in the environmental conditions or the applications themselves. Some of the random errors that may be experienced in the case of electronics include electronic noise in the electrical appliances’ circuit, irregular variations in the rate at which is lost from the appliances, and many others (Aruleswaran, 2010). It is noteworthy that the precision of any instrument, appliance or electronic refers to the proximity of the measurements of the same magnitude to one another. Random errors would, therefore, limit the precision of any appliance (Brusee, 2004).

Systematic errors on their part result from the instruments used to measure the accuracy of the appliances. This may result because something is wrong with the data handling system or the instrument or, in cases where the individuals using the instruments are using them wrongly.

As indicated errors would have serious implications on the performance of the applications. It is always essential, therefore, that the applications undergo verification (gauge verification) in order to ascertain that they are operating within the required ranges. It is noteworthy that irrespective of accuracy in the instruments, there will always be an error. Random errors are unforeseen and would occur even when there conditions are secure for non-scientific and scientific procedures (Brusee, 2010). This is even in cases where all the necessary precautions were taken to prevent them. In essence, there are acceptable ranges within which errors can occur. The verification processes are carried out in an effort to determine whether the working of the appliances is within the acceptable ranges of errors. In case the gauge verification determines that errors are not within the acceptable ranges, efforts would be made to rectify them. These errors would more often than not be systematic. While randomness would be rectified by carried out measurements repeatedly, systematic errors are rectified by changing the measuring instruments (Aruleswaran, 2010).

Conclusion

Gauge verification is carried out in order to ascertain whether or not instruments are operating within the calibration tolerance range. In cases where the results of verification determine that the gauges are not operating within the tolerance ranges, it is recalibrating the gauge would be imperative (Aruleswaran, 2010).
