What should the ohmmeter read when the lead probes are touched together?
When the lead probes of an ohmmeter are touched together, the ohmmeter should read close to zero ohms, indicating a short circuit or very low resistance between the probes.
When using an ohmmeter to check the resistance of a compressor's windings what scale would you use?
the lowest
Can an ohmmeter be used to read a resistance while a source is connected?
Yes. It NEEDS a source to be connected.
Is not used to measure wind?
-- ruler -- ohmmeter -- measuring cup -- bathroom scale -- stopwatch -- frequency counter -- opinion survey
What resistance is in the center of your ohmmeter scale Rx1 range?
What resistance is the center of your ohm scales, Rx1 range?
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.
Is psychrometer not used to measure wind?

When ohmmeter is zero?
It means you have effectively no resistance to current flow. Whether this is good or not depends on whether you WANT resistance to current flow. If you're testing a length of wire, a cable, or something like that, having your ohmmeter read zero would be good. If you're testing a motor or something else that needs to have resistance to work, having your ohmmeter read zero is bad and is called a Short Circuit.
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.

What is the circuit diagram on how to convert galvanomeer into ohmeter?
Just connect a resistor and a small battery in series with the galvanometer,change the markings on the meter's scale, and you have an ohmmeter.
How do you connect an ohmmeter in series or paallel?
A: To read ohms you will use it by reading in parallel and without any external voltage applied
