Actually, measuring winding resistance with a multimeter is an iffy situation at best. This is because the multimeter will not tell you if one of the turns is shorted, causing Q to drastically suffer, it will really only tell you if the winding is open, or if it is shorted to something it should not be shorted to, such as the frame.
This is especially true for larger windings, in larger Transformers and motors, because their DC resistance is so close to zero that you might not be able to tell if they are shorted or normal.
Using a multimeter is a good start, to make sure that basics are covered, and it might tell you if the winding is dead shorted, but you need to know for sure what the expected DC resistance is, and you need to know that you multimeter is very good in the low Ohms scale.

How is an multimeter connected to take a measure?
Multimetres are generaly used to measure the following quantities. Voltage: multimeter is connected in parallel with the Load; Current: multimeter is connected in series with Load; Resistance: the resistor must be taken out of the circuit first, then, the probes from the multimeter are connected across the resistor,
What measures electrical resistance?
an ohm meter OR multimeter is used to measure the electrical resistance...
What are the three main function of the multimeter?
A typical multimeter can measure: * AC & DC voltage (volt) * AC & DC current (amp) * resistance (ohm)
What instruments used in measuring current and voltage?
Multi meterAnswerInstruments that measure current are called ammeters, and instruments that measure voltage are called voltmeters. An instrument that measures resistance is called an ohmmeter. Each of these functions can be combined into one instrument, called a multimeter.
How is the resistance of a motor winding expressed?
The resistance of a motor winding is expressed in
What electrical test instrument is used to measure continuity in a compressor winding?
A digital multimeter (DMM) is commonly used to measure continuity in a compressor winding. By setting the multimeter to the continuity test mode, it can check for a complete electrical path in the winding. If the circuit is intact, the multimeter will emit a beep or display a low resistance value, indicating good continuity. This test helps identify any open circuits or faults in the winding.
How to measure the resistance of a wire with a multimeter?
To measure the resistance of a wire with a multimeter, first turn on the multimeter and set it to the resistance measurement mode. Then, connect the probes of the multimeter to each end of the wire. The multimeter will display the resistance value in ohms.
How do you test the primary and secondary resistance?
To test primary and secondary resistance in a transformer, you can use a digital multimeter. For primary resistance, disconnect the transformer from the circuit, set the multimeter to the resistance (ohm) setting, and measure across the primary winding terminals. For secondary resistance, perform the same procedure across the secondary winding terminals. Ensure the transformer is completely de-energized and isolated from any power source before testing.
How can a multimeter be used to measure the resistance of a circuit component?
A multimeter can be used to measure the resistance of a circuit component by setting it to the resistance measurement mode, connecting the probes to the component, and reading the resistance value displayed on the multimeter screen.
How do you measure the unknown resistance?
You can measure an unknown resistance by using a multimeter set to the resistance measurement function. Connect the unknown resistance in series with the multimeter and apply a known voltage across them. The multimeter will display the resistance value based on the voltage and current readings.
What is the name of the device that measures resistance?
Most multimeter are able to measure resistance.
What equipment do you use to measure resistance?
A multimeter is typically used to measure resistance. It has a setting specifically for measuring resistance and uses probes to make contact with the component being measured. The resistance is then displayed on the multimeter screen.
What is the difference of volmeter and multimeter?
A voltmeter is a device used to measure voltage, while a multimeter is a versatile device that can measure voltage, current, and resistance, among other electrical properties. Essentially, a voltmeter is a specific function within a multimeter.
How do you measure wiring winding resistance?
Through an omhmeter.
Besides voltage and resistance what else can your multimeter measure?
current
What should you do to locate the shorted point in the starting winding?
To locate the shorted point in the starting winding of a motor, first, disconnect the power supply and use a multimeter to check for continuity in the winding. Measure the resistance across the winding; a significantly lower resistance indicates a short. If a short is suspected, you can also perform a visual inspection for any burnt or damaged insulation. Finally, if necessary, isolate individual turns of the winding to pinpoint the exact location of the short.
What will you need to measure to find out which wire has the greatest resistance?
To find out which wire has the greatest resistance, you will need to measure the resistance of each wire using a multimeter. Connect the multimeter to each wire separately and record the resistance values displayed. The wire with the highest resistance value will have the greatest resistance.
