19、 TO A PROCEDURE, PRACTICE, OR CONDITION, THAT COULD POSSIBLY CAUSE DAMAGE TO EQUIPMENT OR PERMANENT LOSS OF DATA. WARNING CAUTION SAFETY 3 A Hipot produces voltages and currents which can cause harmful or fatal electric shock. To prevent accidental injury or death, these safety procedures must be st

20、rictly observed when handling and using the test instrument. SERVICE AND MAINTENANCE User Service To prevent electric shock do not remove the instrument cover. There are no user serviceable parts inside. Routine maintenance or cleaning of internal parts is not necessary. Any external cleaning should

21、 be done with a clean dry or slightly damp cloth. Avoid the use of cleaning agents or chemicals to prevent any foreign liquid from entering the cabinet through ventillation holes or damaging controls and switches, also some chemicals may damage plastic parts or lettering. Schematics, when provided,

22、are for reference only. Any replacement cables and high voltage components should be aquired directly from Associated Research, Inc.

Instruments returned to Associated Research with unsafe modifications will be returned to their original operating condition at your expense. TEST STATION Location Select an area away from the mai

26、n stream of activity which employees do not walk through in performing their normal duties. If this is not practical because of production line flow, then the area should be roped off and marked for HIGH VOLTAGE TESTING. No employees other than the test operators should be allowed inside. SAFETY 4 I

27、f benches are placed back-to-back, be especially careful about the use of the bench opposite the test station. Signs should be posted: DANGER - HIGH VOLTAGE TEST IN PROGRESS - UNAUTHORIZED PERSONNEL KEEP AWAY. Power Dielectric Voltage-Withstand Test Equipment must be connected to a good ground. Be c

28、ertain that the power wiring to the test bench is properly polarized and that the proper low resistance bonding to ground is in place. Power to the test station should be arranged so that it can be shut off by one prominently marked switch located at the entrance to the test area. In the event of an

29、 emergency, anyone can cut off the power before entering the test area to offer assistance. Work Area Perform the tests on a nonconducting table or workbench, if possible. There should not be any metal in the work area between the operator and the location where products being tested will be positio

30、ned. Position the tester so the operator does not have to reach over the product under test to activate or adjust the tester. If the product or component being tested is small, it may be possible to construct guards or an enclosure, made of a non-conducting material such as clear acrylic, such that

31、the item being tested is within the guards or enclosure during the test, and fit them with switches so that the tester will not operate unless the guards are in place or the enclosure closed. Keep the area clean and uncluttered. All test equipment and test leads not absolutely necessary for the test

32、 should be removed from the test bench and put away. It should be clear to both the operator and to any observers which product is being tested, and which ones are waiting to be tested or have already been tested. Do not perform Hipot tests in a combustible atmosphere or in any area where combustibl

33、e materials are present. TEST OPERATOR Qualifications This instrument generates voltages and currents which can cause harmful or fatal electric shock and must only be operated by a skilled worker trained in its use. The operator should understand the electrical fundamentals of voltage, current, and

34、resistance. Safety Procedures Operators should be thoroughly trained to follow these and all other applicable safety rules and procedures before they begin a test. Defeating any safety system should be treated as a serious offense and should result in severe penalties, such as removal from the Hipot

35、 testing job. Allowing unauthorized personnel in the area during a test should also be dealt SAFETY 5 with as a serious offense. Dress Operators should not wear jewelry which could accidentally complete a circuit. Medical Restrictions This instrument should not be operated by personnel with heart ai

36、lments or devices such as pacemakers. TEST PROCEDURES !NEVER PERFORM A HIPOT TEST ON ENERGIZED CIRCUITRY OR EQUIPMENT! If the instrument has an external safety ground connection be sure that this is connected. Then Connect the return lead first for any test regardless of whether the item under test

37、is a sample of insulating material tested with electrodes, a component tested with the high voltage test lead, or a cord-connected device with a two or three prong plug. Plug in the high voltage test lead only when it is being used. Handle its clip only by the insulator-never touch the clip directly

38、. Be certain that the operator has control over any remote test switches connected to the Hipot. Double check the return and high voltage connections to be certain that they are proper and secure. NEVER TOUCH THE ITEM UNDER TEST OR ANYTHING CONNECTED TO IT WHILE HIGH VOLTAGE IS PRESENT DURING THE HI

39、POT TEST. When testing with DC, always discharge the capacitance of the item under test and anything the high voltage may have contacted-such as test fixtures-before handling it or disconnecting the test leads. HOT STICK probes can be used to discharge any capacitance in the item under test as a fur

40、ther safety precaution. A hot stick is a nonconducting rod about two feet long with a metal probe at the end which is connected to a wire. To discharge the device under test, two hot sticks are required. First connect both probe wires to a good earth ground. Then touch one probe tip to the same plac

41、e the return lead was connected. While holding the first probe in place, touch the second probe tip to the same place where the high voltage lead was connected. KEY SAFETY POINTS TO REMEMBER: Keep unqualified and unauthorized personnel away from the test area. Arrange the test station in a safe and

42、orderly manner. Never touch the product or connections during a test. In case of any problem, turn off the high voltage first. Properly discharge any item tested with DC before touching connections. WARNING INTRODUCTION 6 GLOSSARY OF TERMS (as used in this manual) Alternating Current, AC:Current whi

43、ch reverses direction on a regular basis, commonly in the U.S.A. 60 times per second, in other countries 50 times per second. Breakdown:The failure of insulation to effectively prevent the flow of current, sometimes evident by arcing. If voltage is gradually raised, breakdown will begin suddenly at

44、a certain voltage level. Current flow is not directly proportional to voltage. Once breakdown current has flown, especially for a period of time, a repeated application of voltage will often show breakdown beginning at a lower voltage than initially. Conductive: Having a volume resistivity of no mor

45、e than 103 ohm-cm or a surface resistivity of no more than 105ohms per square. Conductor: A solid or liquid material which has the ability to let current pass through it, and which has a volume resistivity of no more than 103ohm-cm. Current: The movement of electrons through a conductor. Current is measured in amperes, m
