How do you measure the resistance of a universal meter?
Beat the multimeter in the resistance! After measuring the resistance test! If there is a display data, that is a good resistance, and vice versa!
Judging from the appearance, you can see if there is no black, crack or fracture, then read from the color ring (which can be seen clearly), there are 5 rings and 4 rings, 2 kinds. 4, the top 2 for effective reading, third is the number 0, the last one is error, the error of 5% gold, silver error 10%5 ring, the top 3 for reading, fourth is the number 0, the last one is error, the error of 1% red brown, as the error was 2% recorded color error was 0.5% + 0.25% for blue purple error numerical error + 0.1% colour: red orange yellow brown 1 2 3 4 5 6 7 gray green blue purple black white 8 9 0 122 0 such as brown red, in front of the 2 digit written directly, is 12. 2 0, 1200 5 + 5% ohm ring as the direct write before 3. It can measure the pointer type multimeter resistance profile to, if you don't know about it from the beginning of high-grade resistance test, reading is too small to a file to decrease, when the pointer in the middle can dial readings. The digital meter is similar, and hits the table to the resistance gear (generally selects the middle gear, for example 20K), reads 0, falls the gear, the reading is 1, rises the gear, until has the accurate reading until
1, the multimeter gear selection on the resistance profile; 2, good resistance measurement at both ends are respectively connected with two pens (stalls can maximize), multimeter resistance indicated as well, indicating no resistance as bad; 3, the measured resistance value of two probes are respectively connected with electric resistance at both ends of the multimeter indication is the resistance value, pay attention to read the unit (file; digital multimeter is "0" to adjust the low point, "1" regulation is a bit higher; the pointer multimeter is "0", "adjust the low point for" high regulation point).
