Multimeters RICHMETERS RM219 (Aneng AN870) and RM303: low cost, performance, and HV insulation test

In this video, I present those multimeters, which are incredible for the price. Also a insulation test is done. 00:00 presentation and description 05:43 difference and thermocouple features 13:28 Voltage readings and accuracy 17:49 Millivolts and RTD readings 20:25 Milliamp readings 29:29 High precision (0,1%) resistor reading 32:31 Miscellaneous measurement, and quickness 44:35 Battery, ergonomy and internals 1:03:52 high voltage insulation test and behaviors
