Electrical circuits are dangerous and can be lethal whe

9、n lack of caution and poor safety practices are used. There are several standard safety precautions that should be taken by the operator. Where applicable, IEC safety markings have been placed on the instrument to notify the operator to refer to the instruction manual for instructions on correct use

10、 or safety related topics. Refer to the following table of symbols and definitions. Symbol Description Direct Current Alternating Current Both direct and alternating current Earth (ground) Terminal. The PULSAR output modules Ground terminals are connected to chassis ground. There is a common chassis

12、N ATTEMPT TO OPEN OR SERVICE THIS INSTRUMENT WHILE CONNECTED TO A POWER SOURCE. LETHAL VOLTAGES ARE PRESENT AND MAY CAUSE SERIOUS INJURY OR DEATH! RadioFans.CN 收音机爱 好者资料库 SAFETY PRECAUTIONS CONTINUED The following are some specific safety related items associated with the PULSAR test system. Always

13、start with the power OFF, before connecting the power cord. Make sure outputs are off before attempting to make test connections. Always use properly insulated test leads. The test leads supplied with the unit are rated for the continuous output ratings of the test system, and should be properly use

14、d and cared for. Do not use cracked or broken test leads. Be careful when using the DC Battery Simulator. The DC is on continuously when the power to the test system is on. Make test connections to the device under test prior to connecting the DC Battery Simulator. Always turn the test system off be

15、fore disconnecting the power cord or removing / inserting output modules. If removing or inserting modules (output modules, timer modules, etc.) turn unit off, wait several minutes and disconnect the power cord from the test system before removing any module. This allows internal power supply chargi

16、ng voltages to dissipate. DO NOT power up without module mounting screws and rear thumb screws secured. UNDER NO CIRCUMSTANCES SHOULD THE OPERATOR PUT HIS HANDS OR TOOLS INSIDE THE TEST SYSTEM CHASSIS, OR BACK PLANE AREA, WITH THE TEST SYSTEM CONNECTED TO A POWER SOURCE AND TURNED ON. LETHAL VOLTAGE

For testing a relay or for monitoring the response of a device, the Timer/Monitor and Battery Simulator Module i

23、s (mandatory) a must. There may be one or more Voltage or Current Modules as required. 1.1 Terminology There are a few terms and definitions that will be used throughout this manual. A brief description follows. 1.1.1 Procedure A sequence of front panel key depressions pertaining to the execution of

24、 a specific function will be collectively called a procedure. 1.1.2 Procedure Diagram A procedure diagram is a diagram that is used to explain the correct sequence and content for entering front panel keys for a single function to the PULSAR unit. Such diagrams contain boxes, lines, text, and someti

25、mes arrows. Horizontal lines without an arrow pointing left that connect boxes (or that connect other lines which eventually connect boxes) indicate logic flow from left to right. Presence of an arrow pointing left indicates logic flow opposite to the default direction. If a vertical line connects t

26、o a line with a left arrow, that vertical line indicates a permissible logic choice only in the direction of that arrow. Other vertical lines 1 that have multiple choices toward the right indicate that each of the choices to the right is logically permissible. 1.1.3 Button Or Key Constants The conte

27、nts of certain boxes within procedure diagrams are key constants. A key constant is a set of capital letters and represents a front panel key (except up and down arrow keys, digits, the colon, and the decimal point). 1.1.4 Procedure Variables A procedure variable is a set of lower case letters that

28、occurs within a box in a procedure diagram. The form and function of each procedure variable is defined in each procedure. 1.1.5 Terminator A terminator is a final box in a procedure diagram for the front panel of the PULSAR unit. The two valid terminators are the key constant EX (the execute key) a

29、nd the empty box. The empty box indicates that the user intends to enter another procedure (function) following this one, and that the user wants this procedure to be executed at virtually the same time as the next procedure. Procedures ending with an empty box are stored until a procedure ending wi

30、th EXECUTE is received. This allows the cancellation of the effect of a human entry time delay between each pair of procedures in a lengthy string of procedures. All procedures between EXECUTE key depressions will be executed nearly simultaneously. The empty box is merely a convenience in a procedur

31、e diagram; it does not correspond to any key depression. EXECUTE A procedure (or string of procedures separated by empty boxes) which ends with an EXECUTE terminator will be executed as soon as it can be processed. 1.1.6 Multiple Choice Symbol The vertical symbol below is the multiple choice beginni

32、ng symbol. This shows the starting point for a procedure diagram which has more than one choice for a starting procedure constant. 2 1.1.7 Shift Key The numeric keypad area contains two possible functions for each key. The digit usage of these keys is accomplished in a normal fashion. The other (mis

33、cellaneous) usage requires, that prior to depressing the target key at its lettered description, one must first depress the Shift key. This Shift key must be released prior to depressing the target key. The Shift keys effect only lasts for the next one keystroke. If that next keystroke is not a key

34、in the numeric keypad area, the prior depression of the Shift key is ignored. 1.2 Input Power And Control Module This module will always be located at the top-left corner of the unit. As mentioned earlier this module is vital to PULSAR operation. This module may be divided into two sections: Power O

35、n section (left half) which is devoted to the power on and reset operation of the unit; and the Control section (right half) which allows manual selection of voltage and/or current generator, selection and setting of AC/DC parameters, selection of phase, frequency and range, timer start/stop control

36、s, selection of SYNC parameters, selection of waveforms, outputs on/off etc. A description of each available switch and its operation is described below: POWER ON/OFF Switch Vertically located in the Power On section of the module, labeled 1/0, this switch energizes a PULSAR unit (1 = ON and 0 = OFF

37、). RESET Switch Located right below the POWER ON/OFF switch, resets the unit to its power-up state without having to power down the entire unit. Use a pencil or a pen to reach and execute. A typical situation when a RESET operation may be required is when there is a communication lock-up between a P

38、ersonal Computer and PULSAR. 3 CONTROL SECTION The right half of the module is called the Control section. It can be divided into five individual menus which offer the following features: SELECT/GENERATOR: VOLTAGE EXECUTE GENERATOR generator # or CURRENT channel # GENERATOR where, VOLTAGE - denotes

39、the VOLTAGE key and indicates that a voltage generator is being selected. CURRENT - denotes the CURRENT key and indicates that a current generator is being selected. generator # or channel # - a single digit in the range of 0 to 9 indicating the generator to be included in this selection. 0 (zero) is pre-defined to mean all generators o
