It depends upon factors such as the needed voltage range, input impedance, accuracy, and temperature sensitivity. For some purposes, a multimeter (which will also measure current and resistance) costing under $10 can be found online at sources such as Amazon. Laboratory instruments can cost thousands of dollars.
Make sure that the test meter is on the correct voltage scale. Place one lead on one of the conductors to be tested and the other lead on the other voltage source conductor. The reading you obtain will be the voltage potential between the two conductors.
When connecting a volt meter to a light bulb to measure the voltage of the light bulb, run a third wire from where the wire enters the bulb to one terminal of the voltmeter and a fourth wire from the other side of the bulb to the other terminal of the voltmeter.
An ohm meter works by sending a small amount of electrical current through a material and measuring the voltage drop across it. By using Ohm's Law (VIR), the meter can calculate the resistance of the material based on the current and voltage readings.
Yes. The voltage across every branch of a parallel circuit is the same. (It may not be the supply voltage, if there's another component between the power supply and either or both ends of the parallel circuit.)
The voltage 208 is a three phase voltage. Single phase is classed as the voltage obtained from any two legs of the three phase voltage system. The voltage between L1 to L2 = 208. L2 to L3 = 208 volts and L3 to L1 = 208 volts. To measure the load of the 208 volt device just clamp an amp meter around one of the legs coming from the load. This will give you the amperage that the load draws.

It depends on how you parked if you parked like and idiot it you cost $150 if your meter ran out it could be $25.
