When using an ohmmeter to check the resistance of a compressor's windings what scale would you use?

the lowest


At which end of the ohms scale are resistance measurement more reliable the zero end or the infinity end?

On an analog ohmmeter, measurements are more precise and more accurate at the zero end of the scale.


Two practical requirements for Optimising the accuracy of resistance measurements for a given ohmmeter?

1). Assure a fresh battery in the meter. (A digital ohmmeter with a low battery will often display a reading as if it's the honest truth, when it's actually a completely bogus measurement.) 2). Use the smallest scale possible, i.e. the lowest scale that's larger than the resistance under test.


Why the zero of the ohmmeter scale is usually at the right end of the scale and reading increase towards the left?

Because the meter is actually measuring the current through the resistor, and the two quantities ... current and resistance ... are inversely proportional. So when the meter measures more current, it has to read less resistance, whereas higher resistance will result in less current. So the numbers for resistance have to be printed "backwards" on the meter scale.

How you can do Calibration of voltmeter by potentiometer?

A: The only calibration that a potentiometer is allow to do is on the resistance scale. The reason being is the internal battery looses capability with age so to compensate the pot. will change current available to make the ohmmeter to go to zero when the probes are shorted. To test a volts range then an accurate voltage must be used to verify calibration.


How To Measure Electrical Resistance?

If you put a current of 1 amp through a resistor, the voltage across it is equal to the resistance in ohms. This can also be done with lower currents and then the result must be multiplied up in the right ratio. An ohmmeter, or the ohm scale on a multimeter, uses a battery to supply the current.


What is the resistance scale on an analog multimeter often termed?

Resistance is measured in ohms, so some refer to the resistance scale as the ohms scale.


How do you determine internal resistance of voltmeter?

By Ohm's law, resistance is voltage divided by current, so you can determine the resistance of a voltmeter by measuring the total current required to drive it to full scale on each range. In typical digital voltmeters, the resistance is fixed at 11 or 20 megohms by a resistor divider. This is not often affected by range, because the op-amp that picks up the divided signal contributes negligible resistance to the divider. In typical analog voltmeters, the resistance is a function of the resistance selected by the range that is placed in series with the meter movement. An example, for a 50 microampere movement is typically 20,000 ohms per volt, so you simply multiply the selected full scale range by 20,000 to get the resistance.


When measuring resistance a reading of ol on the dmm indicates?

probably overload. which means whatever is being measured is beyond the range of the current scale.


At what end of the ohm's scale are resistance measurements more reliable?

Answer: At the zero end, the measurement is more reliable, because all materials have some conductivity, so even the plastic grip of a meters probe, with both your hands making contact with both the probes, will give you some reading at infinity side of the scale.
