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.

What measures electrical resistance?
an ohm meter OR multimeter is used to measure the electrical resistance...
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 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.
What are the three main function of the multimeter?
A typical multimeter can measure: * AC & DC voltage (volt) * AC & DC current (amp) * resistance (ohm)
How is the resistance of a motor winding expressed?
The resistance of a motor winding is expressed in
What is the name of the device that measures resistance?
Most multimeter are able to measure resistance.
What is the difference of volmeter and multimeter?
A volt meter can only measure voltage. A multimeter can measure other items such as resistance and continuity.
Besides voltage and resistance what else can your multimeter measure?
current
How do you measure wiring winding resistance?
Through an omhmeter.
What is resistance of stator winding of induction motor?
Resistance of stator winding is the resistance of the copper conductors being used for building the windings of three separate phases, i.e. R-Y-B. These windings are marked like U1-U2, V1-V2 & W1-W2 at the motor terminals (6 nos.) for the three phases, i.e. R-Y-B respectively. We have simply to measure the resistance of each winding by using a multimeter by connecting the terminals (2 no.) to U1 & U2 and so on. The resistance should be in ohms not milliamps [amps is form of measuring current not resistance] milliamps to microamps in case of large motors, it may be in amps in case of small sized motors. But resistance of each winding should be nearly same to each other. This shows the electrical balance among windings & also proves the healthiness of the winding.
What are three test that the digital multimeter is used for?
To measure voltage, current and resistance.
Which instrunment is used to measure the resistance to earth?
A normal ohmmeter (or multimeter with this feature) should do it.

Can you use the multimeter to measure the resistance of a resistor when there is current passing the resistor?
A: NO the only way is to lift one lead and measure.
How do you know when pressure sensor on manifold is bad?
Measure the resistance with a digital multimeter. If the resistance isn't within spec, it's bad.
What tool can you use to troubleshoot power supply issues measure current resistance or voltage?
multimeter
