This makes the greater the resistance, the more estimates are needed.
The use skill of ohmmeter is to set zero first, and set zero every time you use it. Pay attention to set zero every time you shift gears.
The second point is not to touch the stylus with your hands, which is safe and accurate.
Third, the reading should be relatively accurate. The method is to wait for the hands to swing stably and the line of sight is perpendicular to the hands. Looking down, a good watch has a small mirror under the dial, so that the two hands (below) overlap and then read.
The fourth point is the multiplication of dial scale and resistance ratio.
The fifth point is the estimation level. For the resistance with larger resistance, only the one with higher resistance can be used to measure, so that the estimation is more accurate, and the pointer is biased to the middle or right as far as possible.
When you say 14, the pointer is in the middle position. The reading here is more accurate. Just after alignment, the line of sight and the pointer are perpendicular to 14. Whether it is left or right, you have to estimate. It is estimated that it is divided into five equal parts (or three equal parts) between 14 and 15, right in the middle. Then multiply by the ratio of the upper gear.
When learning, you can compare a digital table and gradually experience the estimation skills.
