a multimeter probably has a Ohm meter as well. If yes, use it and make sure you have the correct scale adjusted. If there is no Ohm meter you should calculate the resistance using Ohms Law. So if you use your multimeter as an Amp meter (in series with the unknown resistor) and you apply a know voltage across you should be able to calculate the resistance by dividing the voltage you applied by the current you meassured (R=v/I)
ANSWER: 1 make sure ther is no external power connected 2 short the leads together and adjust for zero reading on the meter. This step is necessary to eliminate the internal battery drifting with time.
Unlike voltage and amps reading the scaling of the meter is not important to begin with since a peg meter or a overflow will not destroy the meter immediately but do change the scale to get maximum deflection or digital display.That it

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,
Functions of a multimeter?
A multimeter combines the functions of an ammeter, voltmeter, and ohmmeter and, so, can be used to measure current, voltage, and resistance by selecting the appropriate scale/setting.
How do you measure earthing using multimeter?
only earthing can not be measure. Anyone can only measures the voltage and the current with respect to the earthing .Thus it is impossible to measure the earthing.
What would you do to measure the current in a resistor?
Since the current in a resistor is the same as the current in the leads/wires on either side of the resister, I might use a clamp meter such as an Amprobe to measure current, if the current was alternating (AC). Otherwise, I would have to break one of the leads and insert an ammeter or a multimeter with an amp setting into the circuit. Afterwards the broken connection would have to be repaired.
What instruments used in measuring current and voltage?
An OHMmeter.In a Turkish source, I found that resistance can be measured by a resistance meter.One important measurement that can be made with a multimeter is a resistance measurement. Not only can these be made to check the accuracy of a resistor, or check it is functioning correctly, but resistance measurements can be required in many other scenarios as well. It may be to measure the resistance of an unknown conductor, or it may be to check for short circuits and open circuits. In fact there are many instances where measuring resistance is of great interest and importance. In all these cases a multimeter is an ideal piece of test equipment for measuring resistanceSimple resistance may be measured directly with a multimeter. A small voltage is impressed across the unknown resistor, and the current developed is measured. The result is presented directly as Ohms.An ohmmeter.Ohm meter (Usually part of a multimeter but may be stand alone especially in a laboratory)A digital multimeter (DMM) will measure resistance, along with voltage, current and impedance.
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.

Can you calculate the resistance of a component using a meter and a resistor?
yes you can! you can use a multimeter and a resistor.
What type of meter would be connected on both sides to a resistor in a current?
A multimeter set to measure current (in amperes or milliamperes) would be connected in series to the resistor to measure the current flowing through it. The multimeter would be placed in series with the resistor to accurately measure the current passing through it.
How can I measure hertz using a multimeter?
To measure hertz using a multimeter, set the multimeter to the frequency measurement mode. Connect the multimeter's probes to the circuit or device you want to measure. The multimeter will display the frequency in hertz.
What is the procedure for measuring frequency in hertz using a multimeter?
To measure frequency in hertz using a multimeter, set the multimeter to the frequency measurement mode. Connect the multimeter's probes to the circuit or signal you want to measure. The multimeter will display the frequency in hertz on its screen.
How do you measure life in a battery?
by using a multimeter.
Why does resistance value measured using multimeter differ from one decoded using colour band?
Resistors have tolerance. So does the multimeter. Standard resistors range from 20% (no fourth band), to 10% (fourth band silver), to 5% (fourth band gold). Resistors will not normally measure exactly what you expect, and proper circuit design must take this into account.The multimeter may not be calibrated correctly.
What will be the resistance of a 10kohm resistor when measured using the multimeter with the terminals reversed?
Approximately 10,000 ohms.
How can I accurately measure amps on a 240V circuit using a multimeter?
To accurately measure amps on a 240V circuit using a multimeter, you need to set the multimeter to the current (amps) setting, then connect the multimeter in series with the circuit. Make sure to follow safety precautions and consult the multimeter's manual for specific instructions.
How do you know if the resistor is defective?
To determine if a resistor is defective, you can measure its resistance using a multimeter. If the measured resistance significantly deviates from the resistor's specified value (indicated by its color code), it may be faulty. Additionally, visual inspection for physical damage, such as burns or cracks, can also indicate a defective resistor. If the resistor is part of a circuit and the circuit is not functioning properly, it may be worth testing the resistor as a potential cause.
Can you measure the internal resistance of dry cell using multimeter?
Well, you do use a multimeter to measure it, but not directly. You need at least one other thing besides the multimeter and the dry cell. Here's a simple way to do it: -- Take a resistor. With the meter set to measure resistance, measure the resistor's value. Call that 'R'. -- With the meter set to measure voltage, measure the voltage of the dry cell. Call it 'V1'. -- Connect the resistor across the dry cell. Measure the dry cell's voltage again. Call it 'V2 ' this time . V2 will be less than V1 . The internal resistance of the dry cell is R times (V1 - V2) / V2
