The group of physicists from the secondary school. Rastopulovka multimeter shows nothing when measuring the resistance of 2D-resistor ... Why? The first thing that comes to mind - the toggle switch for 2000 ohms (usually fixed very high resistance). The second - to move the test leads, look for a place that was still reading. Third, draw a "fatter" ... In any case, the result should be tested more than once ... Good luck!
Many people like (and I, to be honest) that the processing of the results does not take much time - and took a picture of it! However, I would like to see high-quality tables, graphs (using computer programs). Let's still try to process the results of modern way !!!
