PARTS LIST If you are a student, and any parts are missing or damaged, please see instructor or bookstore. If you purchased this kit from a distributor, catalog, etc., please contact Elenco mail is at the back of this manual) for additional assistance, if needed. DO NOT contact your place of purchase as they will not be able to help you. - Page 3 IDENTIFYING RESISTOR VALUES Use the following information as a guide in properly identifying the value of resistors. BAND 1 1st Digit Color Digit Black Brown Orange Yellow Green Blue Violet Gray White IDENTIFYING CAPACITOR VALUES Capacitors will be identified by their capacitance value in pF (picofarads), nF (nanofarads), or µF (microfarads). Most capacitors will have their actual value printed on them.

Page 4: Theory Of Operation
Figure 1. Figure 1 Solid Liquid The glass tube in your strobe light kit is filled with a rare gas called Xenon. This gas is used because it is easy to ionize. WHAT IS AN ION? Gas atoms have no electronic charge on them in their normal state. - Page 5 Figure 3 Negative Charge on Plate GENERATING AN ELECTRIC FIELD In order to ionize the Xenon gas in the glass tube, the 3 volts DC at the battery must be transformed into hundreds of volts DC. One of the electronic devices used to “step up”...

Page 6: Schematic Diagram
THEORY OF OPERATION A block diagram is used to break down a system into sub-systems that are easier to explain. strobe lights will have the blocks shown in Figure 8. The power supply, Block 1, can be either an AC (Alternating Current) or DC (Direct Current) source of electrical power. - Page 7 CONSTRUCTION Introduction The most important factor in assembling your AK-520 Strobe Light Kit is good soldering techniques. Using the proper soldering iron is of prime importance. recommended. The tip of the iron must be kept clean at all times and well tinned.

TROUBLESHOOTING Consult your instructor or contact Elenco purchase as they will not be able to help you. 1. One of the most frequently occurring problems is poor solder connections. Tug slightly on all of the parts to make sure that they are indeed soldered. 2. - Page 12 QUIZ 1. All matter is composed of atoms arranged in patterns called _______________. 2. In their normal state, the net charge on a molecule of gas is _______________. 3. When a molecule of gas is positively charged it is called a _______________. 4.
