How to Test a Metal Halide Ballast with a Multimeter?
Dec 21, · Hold the white wires together and insert one probe of the multi-meter with it. Insert another probe with other wires generally red, blue, and Yellow. However, some multi-meter has only blue and red wire. If the ballast is right in condition, it will show resistance in the multi-meter. Touch your digital multimeter’s probes to one white wire and one colored wire that run from the Ballast. Ballast that is working will read a continuous circuit. For Ballast that’s not working correctly, a replacement should be done.
Although metal halide bulbs are long-lasting, still they wear out. So when you begin to experience rapid flickering, dimming, buzzing and changing colors, the fault could be with the bulb, but most times it is a faulty ballast. You should have some checkings performed on your ballast.
While checking the ballast, you need to see if there is any burn marks, swollen cases or leaking oil. These faults would help you conclude on the ballast as the faulty part.
We have explained a few tests and guidelines that you can carry out on your metal halide ballast. Following the steps below would help you troubleshoot your ballast without any issue. The primary way of determining the problems of the ballast is by testing it, and for this test to be carried out, you would need a multimeter. Extech EX is how to test a hid ballast with a multimeter good one see on Amazon. And here you can find the list of the best multimeters in Check for the high voltage side of the tombstones for continuity.
On a typical metal halide lamp, one or two wires goes into each fixture, the yellow or blue wires indicate the power wires, while the white wire would be neutral. The next thing to do is to touch one probe of the multimeter on the white wire from the ballast and the other on the other colored wire from the ballast, like in the video below. After this step, your multimeter should show a continuous circuit if your ballast is still working correctly, but if it is not, then you might have to replace it.
To run a test on the low voltage side of the metal halide ballast, you would begin by removing the nuts from the wires that come from the power feed side of the ballast.
Most of the wires appear to be black and white, so the touch the probes of your multimeter on these wires. How to replace a metal halide ballast? Watch the video below. Before carrying out these tests, you should observe the ballast, by exposing it.
To reveal it, use a screwdriver to remove its protective covering, then check it to see if there is how to disable password lock on blackberry curve leak on it. The leaking oil proves that pressure from excessive heat has broken the internal seal, so if how to format 64gb micro sd card to fat32 observe any leak, you should replace the entire thing.
You can also look inside the ballast for a blown fuse that would need to be replaced. For safety, the first thing to do before carrying out any electrical test is to shut off the electricity running through it, so you would need to remove the lamp from its electrical source and wait for a few minutes to allow any current stored within the ballast dissipate in the light circuit. Next, remove the bulb from the tombstones that hold it at each end. Well, if you have tested the high voltage of your ballast and it is functioning correctly, then you should examine the low voltages of your ballasts.
If both still appears to function properly, you should check the wire connections from the tombstones, as one wire could be the reason why of your ballast is working correctly. It could also be a case of a loose socket. If this is the case, tighten the bulb and when you notice it is blown, replace it. Your email address will not be published. Skip to content.

Nov 30, · Short video (sorry for the terrible quality) that shows how to test a xenon HID ballast, ignitor, and bulb. These ignitors can push up to 25, volts, so do. Metal halide bulbs, high-pressure sodium bulbs and mercury lamps make up the family of high-intensity-discharge (HID) lighting. A ballast serves as a lamp starter and regulates power to the light. The ballast assembly consists of a transformer, capacitor and lamp starter sized for the specific type of lamp. To run a test on the low voltage side of the metal halide ballast, you would begin by removing the nuts from the wires that come from the power feed side of the ballast. Most of the wires appear to be black and white, so the touch the probes of your multimeter on these wires.
In our day to day life, we use electronic ballast to the fluorescence bulb in our houses as well as work-space. Several times we face problem-related to damaging the electronic ballast. You might have suffered such situations. You must have tried to know how to test an electronic ballast. However, testing an electronic ballast is not a difficult task to do. One can quickly troubleshoot an electronic ballast with a digital multi-meter — all you need to know some basic concepts about the testing system and equipment.
In this article, we have tried to give a clear concept about how to test an Electronic Ballast with a Digital Multi-meter. An electronic ballast is a device which is used to limit the current of a load such as tube light or fluorescent lamps. It is also called a starter because of its action. At the time of starting of fluorescence bulb, it needs more voltage. The ballast limits the current by increasing the energy for the lamp.
There are mainly three types of ballast. Those are:. Therefore, it works as an additional load resulting in limiting the current as well as increasing the voltage required to start the bulb or lamp. A big question might come to your mind that, what will happen in the absence of a ballast to the circuit. The answer is the lightening device may damage immediately or in the long run. A ballast is a kind of resistor who resist the current in the electrical circuit. Without a ballast, the current in the circuit can be random.
By this situation can cause the device to burn or damage. Moreover, it also decreases the starting time an electrical lightening device. Generally, a good ballast will work immediately as soon as the switch is turned on. On the other hand, a faulty ballast will not work correctly.
If you face the underlined signs to weight, you should check the ballast. However, all these things are the ways to check a ballast physically. You might also test the ballast with a digital multi-meter.
Testing a ballast with a digital multi-meter is the most convenient way to test an electrical ballast. It is less time consuming, and you can be even more sure about the ballast.
A multimeter is a must-have tool as an Electrician. You can have a quality kit under USD. A digital multi-meter has a monitor which shows the result in digital format, i. In opposite to this in an analog multi-meter , it has a mechanical system. A digital multi-meter is more comfortable to operate than an analog one. A multi-meter measures current, voltage as well the resistance and capacitance of a device or circuit.
It also can check the continuity of a course. It can operate multiple functions. That is why it is called a multi-meter. You can follow the below-mentioned steps to test a ballast with a multi-meter.
Remember, precautions are first as you are working with electrical devices, which generally hazardous. Here I have discussed five steps on how to test an electrical ballast with a Digital Multi-meter.
For any electrical works, you must ensure that the circuit breaker is in the OFF position. So, turn the breaker off at first. Be sure about the switch which one is connected with the devices you want to test. As the ballast generally connects with a bulb or lighting devices. Try to remove the bulb according to its settings because different machine has different installation process.
For example, a round-shaped fluorescent bulb is connected to a socket along with the ballast. On the other hand, a U-shaped bulb is connected to spring tension, so you need to remove it by clockwise or anticlockwise turning. Open the cover and unplug the ballast form the connection. However, different design has different sections to install the ballast. Check the multi-meter ohm setting. Hold the white wires together and insert one probe of the multi-meter with it.
Insert another probe with other wires generally red, blue, and Yellow. However, some multi-meter has only blue and red wire. If the ballast is right in condition, it will show resistance in the multi-meter. On the other hand, if it is damaged or in bad shape, there will be no multi-meter rating , and you need to replace the ballast. As soon as the testing has done, you are pretty sure what to do. If you need to change the ballast, do it and install in the same way.
If the ballast is okay, then the problem may be in other devices. So properly reinstall the ballast. All the things mentioned above can help you to fix simple problems in an electrical ballast. Again, it will also save your time and money. If you can follow the process correctly, you will not need an electrician for this simple testing job. However, always keep in mind that precaution first, so turn the power OFF before doing all of these. Your email address will not be published.
