In fact other forms of test equipment that measure resistance also use the same basic principle. The basic idea is that the multimeter places a voltage at the two probes and this will cause a current to flow in the item for which the resistance is being measured. By measuring the resistance it is possible to determine the resistance between the two probes of the multimeter, or other item of test equipment. How to measure resistance with an analogue multimeterĪnalogue multimeters are good at measuring resistance, although they are a few points to note about the way in which it is done. Digital car meter riding changing software how to# The first point to note is that as the meter itself responds to current flowing through the component under test. A high resistance corresponds to a low current and the meter needle settles on on the left hand side of the dial, and a low resisatnce corresponds to a higher current and the meter needle deflects more so it appears on the right hand side of the dial as shown below. It will also be noticed that the calibrations become much closer together as the resistance becomes higher, i.e. Analogue multimeter face calibrationsĪnother aspect of using an analogue multimeter for measuring resistance is that the meter needs to be 'zero'ed' before making a measurement. This is done by connecting the two probes together so that there is a short circuit, and then using the 'zero' control to give full scale deflection on the meter, i.e. zero ohms.Įach time the range is changed, the meter needs to be zero'ed as the position may change from one range to the next. The meter needs to be zero'ed because the full scale deflection will change according to aspects such as the state of the battery.
