Essentially the words tachometer and speedometer have identical meaning: a device that measures speed. It is by arbitrary convention that in the automotive world one is used for engine and the other for vehicle speed. In formal engineering nomenclature, more precise terms are used to distinguish the two.<\/div>\r\n<div>\u00a0<\/div>\r\n<div>\u00a0<\/div>\r\n\t\t\n<style>\n#text-4167552439 {\n  line-height: 2;\n}\n<\/style>\n\t<\/div>\n\t \t<div class=\"img has-hover x md-x lg-x y md-y lg-y\" id=\"image_1881690441\">\n\t\t\t\t\t\t\t\t<div class=\"img-inner dark\" >\n\t\t\t<img loading=\"lazy\" decoding=\"async\" width=\"1020\" height=\"575\" src=\"https:\/\/techmaster.com.vn\/wp-content\/uploads\/2020\/12\/may-phat-tan-so.jpg\" class=\"attachment-large size-large\" alt=\"M\u00e1y ph\u00e1t t\u1ea7n s\u1ed1\" \/>\t\t\t\t\t\t\n\t\t\t\t\t<\/div>\n\t\t\t\t\t\t\t\t\n<style>\n#image_1881690441 {\n  width: 100%;\n}\n<\/style>\n\t<\/div>\n\t \t<div id=\"text-3150526100\" class=\"text\">\n\t\t\r\n<div>\u00a0<\/div>\r\n<div>\u00a0<\/div>\r\n<div>\u00a0<\/div>\r\n<div>\u00a0<\/div>\r\n<h3 style=\"text-align: center;\"><span style=\"font-size: 115%;\"><span style=\"font-size: 115%;\"><strong>FREQUENCY COUNTER\/TIMER<\/strong><\/span><\/span><\/h3>\r\n<div style=\"text-align: justify;\">Frequency counters are test instruments used in many applications associated with radio frequency engineering to measure the frequency of signals very accurately.<br \/><br \/>These frequency counters and counter timers are widely used within a variety of areas of electronics test to measure the frequency of repetitive signals, and also for measuring the time between edges on digital signals.<\/div>\r\n<div>\u00a0<\/div>\r\n<div>\u00a0<\/div>\r\n<div>\u00a0<\/div>\r\n<div>\u00a0<\/div>\r\n<div style=\"text-align: center;\">\u00a0<\/div>\r\n\t\t\n<style>\n#text-3150526100 {\n  line-height: 2;\n}\n<\/style>\n\t<\/div>\n\t \t<div class=\"img has-hover x md-x lg-x y md-y lg-y\" id=\"image_569353288\">\n\t\t\t\t\t\t\t\t<div class=\"img-inner dark\" >\n\t\t\t<img loading=\"lazy\" decoding=\"async\" width=\"1020\" height=\"575\" src=\"https:\/\/techmaster.com.vn\/wp-content\/uploads\/2020\/12\/may-phan-tich-pho-thoi-gian.jpg\" class=\"attachment-large size-large\" alt=\"M\u00e1y ph\u00e2n t\u00edch ph\u1ed5 th\u1eddi gian\" \/>\t\t\t\t\t\t\n\t\t\t\t\t<\/div>\n\t\t\t\t\t\t\t\t\n<style>\n#image_569353288 {\n  width: 100%;\n}\n<\/style>\n\t<\/div>\n\t \t<div id=\"text-889445250\" class=\"text\">\n\t\t\r\n<div>\u00a0<\/div>\r\n<h3 style=\"text-align: center;\"><strong><strong>OSCILLOSCOPE<\/strong><\/strong><\/h3>\r\n<div style=\"text-align: justify;\">An oscilloscope, previously called an oscillograph, and informally known as a scope or o-scope, CRO (for cathode-ray oscilloscope), or DSO (for the more modern digital storage oscilloscope), is a type of electronic test instrument that graphically displays varying signal voltages, usually as a calibrated two-dimensional plot of one or more signals as a function of time. The displayed waveform can then be analyzed for properties such as amplitude, frequency, rise time, time interval, distortion, and others. Originally, calculation of these values required manually measuring the waveform against the scales built into the screen of the instrument. Modern digital instruments may calculate and display these properties directly.<\/div>\r\n<div>\u00a0<\/div>\r\n<div>\u00a0<\/div>\r\n<div>\u00a0<\/div>\r\n<div style=\"text-align:
