how to test a metal halide ballast with a multimeter

Set the ohm setting on the multimeter. Maintaining an optimum electrode temperature is the key to long lamp life. An electronic ballast is a device which is used to limit the current of a load such as tube light or fluorescent lamps. First, the line voltage goes into the ballast. Most metal halide ballasts operate on 120-277V. X, How do you then know when it is bad and needs replacement? Through a gas mixture in the arc tube, MH lamps begin when their ballast provides a high starting voltage higher than that supplied to the lamp electrodes. This explanation probably applies to other metal halide bulb sizes (wattages) as well. Your fluorescent bulb looking like it is burnt at its extreme ends (due to dark spots) is another sign to watch out for. Turn on the lamp and touch the ends of the tester leads to the lamp electrodes with the bulb in place, then remove the bulb and make the same test. There are mainly three types of ballast. How many lumens does a 175 watt metal halide put out? To start the lamp, regulate the lamps starting and operating currents, and provide adequate sustaining supply voltage, metal halide (MH) ballasts are required. Remove the protective covering using a screwdriver. x\}WpFm( M9$F:}%e8x?SC{)\p D*OOhyMwu.7/gGyY]}l+T1{{ jeQyikqi@ Causes of Ballast Failure. 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. You might have suffered such situations. You might also test the ballast with a digital multi-meter. Images related to the topicMetal Halide bulb wont start, wont light; Troubleshooting 175 watt metal halide bulb. Metal halide bulbs are long lasting, but they do eventually wear out. Turn on the lamp and touch the ends of the tester leads to the lamp electrodes with the bulb in place, then remove the bulb and make the same test. If the reading is infinite, that means the ignitor is open and not working properly. If yes! Pumps, but Wont VIDEO In this way, how do you know if your washing machine motor is bad?

Identify any leaky areas. Using your voltage meter, test the voltage. Metal halide lamp ballast. 1) They use an arc to illuminate rather than a piece of metal. It helps to restrict the amount of voltage running through the circuit so a fragile component within it doesnt get damaged. Switch to an electronic ballast, keep lamp. You can find the resistance and voltage of electricity. If the reading is between 240-277 volts, then the ballast is working properly. Now that you know which wires go where, connect one lead from your incandescent lamp to eachofthe corresponding wires coming out oftheballastterminals(one wirefromtheballastonetoone wirefromthelamp). Adjust the multimeter to measure frequency and replace the ballast if the reading is not between 20 and 50 kilohertz. Each halide salt has a certain color profile that it adds to the finished light output, and a specific temperature has to be maintained in order to keep the lamp at the same color consistency. Here I have discussed five steps on how to test an electrical ballast with a Digital Multi-meter. This is achieved by painting the pinched edges of the arc-tube white to reflect light back into the chamber.Mercury VaporRather than having any secondary elements in the arc tube to control the light color, a mercury vapor relies solely on the blue light emitted from vaporized mercury (which all 3 of these lamps have). Lets get right in. MOST POPULAR TESTERS in this convenient kit feature three products for a MULTIMETER FEATURES of the MM300 include measurement up to 600V AC/DC VOLTAGE TESTER APPLICATIONS include 50 to 1000V AC power detection range Lightening device to attach the counterweight. Signs that a Metal Halide light bulb or ballast needs replaced: The lamp appears to be a different color, or are turning pink; This is known as color shift, a natural effect of Metal Halide over long periods of operation. Set the multimeter to an ohm setting. Without a ballast, the current in the circuit can be random. Extremely high temperatures cause it to burn, while extremely low temperatures prevent it from even starting the fluorescent bulbs at all. If you get a low reading (below 100 ohms), that means the ignitor is shorted and also not working properly. Dignified and upright. Now, you proceed to take off the casing covering the ballast. Keep the lamp on and switch to an electronic ballast. Use two wires to connect the ballast to the car battery. << /Length 5 0 R /Filter /FlateDecode >> The reading on the multimeter should be between 120-277 volts AC. .

If the meter indicates a very low resistance then gradually increases, the capacitor does not require replacement. 4 0 obj Some are simply unscrewed while others require you to pop them out of their tombstone sockets. When you start a metal halide lamp it will flicker wildly for a second or two then it will turn to a dark green/blue Glow as the arc stabilizes it will gradually get brighter and whiter over 5 minutes till it reaches full brightness at that point if you shut it off it will take as long as 15 minutes before it will restart again . Ballasts are not just used to protect them, but also to control whether they start or not. By this situation can cause the device to burn or damage. Check the ballast output with a voltage tester. If youre troubleshooting a lamp with an ignitor, you may need to test the ignitor with a multimeter. Then, set your multimeter to the ohms setting and touch the probes to the two terminals on the ignitor. Activate the circuit breaker at the switch to cut off power and avoid getting electrocuted. Rather, they require a period of time-, To put it simply, metal halide technology works, Metal halide lamps are a type of arc lamp known as a gas discharge lamp. To test a ballast, we need the following things. The resistance should be high; if it is not, then there may be something wrong with the ballast itself and it should be replaced. The bulb that comprises the lamp contains electrodes as well as a mixture of metal halides (salts) mercury vapor, and an inert gas to sustain the process, such as argon. Disconnect or turn off all other electrical components that are on the same circuit as the lamp and then try the lamp again. Low output. Those are: A ballast needs to connect in series with the circuit. Make surethatyouhavea good connectionbetweenallofthewires; ifnot,. Turn on the lamp and touch the ends of the tester leads to the lamp electrodes with the bulb in place, then remove the bulb and make the same test. The voltage difference will indicate the results. Place the black probe on the white ground wire and the red probe on each of the other wires. His honesty is unquestionable. How would you find if the ballast is prone to damage? Lets talk about how to test an electric ballast with a digital multi-meter. To check the ballast efficiency, first identify any physical damage of leakage, loose sockets, discoloration, and bulging out of the ballast. A voltage tester can be used to check the ballast output. Much like a fluorescent lamp, a mercury vapor lamp utilizes phosphorescence to control the color. If your metal halide lamp does not start or burns irregularly, there may be a problem with the ballast or the bulb. There are certain signs your fluorescent bulb gives out that point to a faulty ballast. it may also present a 1 reading, which represents a high or infinite resistance. Connect the ballast to the car battery with two wires. You would be testing each of these yellow, blue, and red wires against the white ground wire for faults. If it turns on, the circuit is probably overloaded. Washer Wont Pump or Spin. If youre troubleshooting a ballast for an MH lamp, you can use a digital multimeter to check it.
