For violin tuning, use the pegs initially to bring the string close to the desired pitch and then use the violin fine tuners (if you have) for the desired pitch. In order for tuning violin, the A string is first tuned to a standard pitch (usually 440 Hz) using either a tuning fork or another electronic tuning instrument. You can also tune the violin to a fixed pitch instrument such as a piano. The other strings are tuned against each other in intervals of perfect fifth* (refer faq) by bowing them in pairs. 


If all the 4 strings are way out of tone, each string should be tightened by 1-2 note increments on one string at a time and then tighten the next string.  Tightening one string all the way to the desired pitch while leaving the other strings very loose may create unequal pressure on the bridge causing it to fall.

If you have just started with your violin study, you may sometimes find it difficult to identify the correct pitch even with this online tuner. There are several electronic violin tuning instruments such as the Korg CA30 Chromatic tuner available in the market which makes violin tuning easier especially for beginners. Most violin tuners use LEDs to indicate the pitch and a large analog meter to show exactly how close the pitch is to ideal. Some tuners require you to specify the required pitch whereas some have the ability to detect the target pitch. Here are some of the leading violin tuners in the market.

In the below listed tuners, refer  Intelli Metronome and tuner under Violin humidifiers and hygrometers heading in the page Violin parts

In this video heading it says metronome, but it is a violin tuner and is said again in the video. Korg CA-1,   Korg CA-30 and many other tuners work exactly like this.

The important thing here is that when we start with A string the tuner might show a D or G or any other tune. This is because the  A string is way out of tune and we have to bring it very close to A ( that is G or B) using the pegs or a fine tuner and then use the tuner as a guide to reach the perfect A note which is when the needle stands straight up.

Korg TM-40 is a violin tuner and metronome so you can combine two functions in one. .

You may also use Tuning forks and pitch pipes for violin tuning even though they are not  easy to tune as electronic  tuners.
