I have seen prices as low as $15 and as high as $150 or more. I personally would not trust one on the low end, the cheep end of what I would spend would be around the $50 range to ensure you're getting something accurate.
Then again, I work with computers, and a very small mistake can mean destroying a computer.
But if u are using it once, the cheap one will work

What is a micro voltmeter?
A microvoltmeter is a type of voltmeter with special calibration. This special calibration allows it to show the values of voltages in microvolts.
Which of these is used to measure potential difference in parallel circuits?
voltmeter
Where ammeter and voltmeter are put in circuit?
Place in parallel anywhere in the circuit. One lead goes to the hot, the other to the neutral.
What is the calibration of ammeter?
An ammeter should not be used as a voltmeter. An ammeter is a low impedance device that measures the current going through a circuit, often by measuring the small voltage across a known resistance. A voltmeter is a high impedance device that measures the voltage across a circuit. If you were to connect an ammeter as if it were a voltmeter, you would effectively short out the circuit, drastically affecting its operation, and potentially damaging both the circuit and the ammeter.
How much does a slurpee cost?
about $1.25
How does a electrodynamometer work as a voltmeter?
An electrodynamometer can work as a voltmeter by judging the wavelength and force of the electricity, much the same at the voltmeter, then converting it to a force that is more recognizable.
How much does a voltmeter cost at a tool store?
I picked up a digital multimeter at Harbor Freight Tools for 3 dollars last month. (August of 2011)
How much is a voltmeter?
A cheap one from radio shack $5
Why is ideal resistance of a voltmeter infinity?
generally voltmeters are connected in parallel in the circuit.If the voltmeter resistance is lower as it increases the current rating,because by connecting parallel we are decreasing the resistance,so if the voltmeter resistance is not too much higher it leads to burning of the meter,For that we can conclude that the in ideal the voltmeter has infinite resistance.
Voltmeter in series?
No. Voltmeter in parallel. Ammeter in series.
How do you convert voltmeter to ohmmeter?
First you will need a constant current source. Do NOT connect the voltmeter to the constant current source without the resistor to be measured already connected. Do NOT use a battery, it is a voltage source. Then follow these steps to measure a resistor:connect the voltmeter across the resistor to be measuredconnect the voltmeter-resistor combination across the constant current sourceread the voltmeter and record the voltagedisconnect the voltmeter-resistor combination from the constant current sourcedisconnect the voltmeter from the resistorcalculate the resistance from the measured voltage and current from the source with Ohm's law in this form: R = V ÷ IIts much easier to just use the ohms setting on a multimeter.
What is a dc voltmeter?
It is a voltmeter which can only measure direct current.
What does a voltmeter measure voltage in?
A voltmeter measures voltage in volts.
Which type digital voltmeter is the of fatest all digital voltmeter?
You mean fastest? Digital voltmeter gives reading in seconds.
What are the disadvantages of using ammeter and voltmeter?
The disadvantage of using a voltmeter and ammeter on circuit measurements is that internal burden in both these instruments can affect circuit operation so much as to make a measurement useless.
What methods would you use to test the resistance of a long and short wire?
By placing a voltmeter either side you can see how much electricity goes through the wire. This is because a voltmeter measures the difference in volts.
What is the voltmeter reading this time?
positive terminal
