^^^^^ Very good video (), but just a note of caution - professionals (like the folk @ RT and Charles-the humble mechanic) correctly invest in good test equipment because it makes commercial sense to do so.What this means is that when these types of videos are made, there is an implicit assumption that what the meter reads is actually correct - and in most videos, the reading is correct (to the accuracy of the meter)
However unless Joe-average is an enthusiast, he/she generally has less financial justification when choosing which multi-meter to buy. But this notwithstanding, Joe-average generally has the same unshakable degree of confidence in the reading shown on the meter screen and on lots (most?) domestic multi-meters this confidence is misplaced .
The particular issue when "domestic" multi-meters are used for parasitic leakage analysis is that the test numbers are usually very small and this exacerbates the meter inaccuracy issue (which is further complicated by the noisy electrical environment in which the test is performed). This reading inaccuracy (@ small volt-drop numbers) makes the current draw number from the reference table in the video somewhat fungible (in my bitter experience)!
So, if I may interpose a further point of complication to an otherwise excellent video - certainly do all the multi-meter tests shown in the video as a precursor to measuring the volt-drop across the fuse, but consider also that multi-meters sometimes tell deliberate lies (it's not their fault)! Even if your preliminary multi-meter tests are successful - just because the meter screen says 3 milli-volts, doesn't mean that the volt-drop is actually 3 milli-volts!
