One, instrument of overview JBC-03 protection is me the tall intelligence that the factory develops on original basis is changed, muti_function instrument of protection desired result. This instrument uses microcomputer technology, by only a machine, logistic control the unit, bell, printer composition when handing in voltage of dc electric current to output data of unit, high accuracy to collect LCD of unit, LCD, real time, measure precision tall, repeatability is good. This instrument still has an appearance beautiful, function is reliable, the operation is handy, advantage of functional neat congruent, it is the testing instrument of ideal of unit of desired result protection. JBC-03 protection instrument can check all sorts of handing in dc electric current, voltage, among, a variety of individual relay such as brake of signal, coincide, differential and screen of groups of whole protection, the suction that can check all sorts of relay combines tension (electric current) value, release voloage (electric current) value, all sorts of touching first (often leave, often shut, changeover, delay time) suck close time and disconnect time, all check automatically 3 times, automatic computation all is worth 3 times, can print test result. 2, characteristic of JBC-03 protection instrument used personal computer control as a result of this machine, chinese character clew is operated. This machine still sets self check to sign up for wrong function, this machine after switching on the mobile phone invests self check instantly, went to the lavatory greatly examination, maintenance. If " is sucked,add up to voltage " , " to disconnect voltage " , " often leaves suck add up to time " to wait. 3, JBC-03 protection instrument is main technical parameter 1, alternating voltage output: 0 ～ 250V is successive and adjustable, 1000VA 2 of capacity of the biggest output, alternating current outputs: 100A of 0 ～ 20A, 0 ～ is successive and adjustable when 0 ～ 20A, when 100A of ～ of 5V 0 of open circuit voltage, 10V 3 of open circuit voltage, volts d.c. outputs: 0 ～ 300V is successive and adjustable, the biggest 3A 4, dc sheds output: 5A of 0 ～ 200mA, 0 ～ is successive and adjustable when 0 ～ 200mA, when 5A of ～ of 48V 0 of open circuit voltage, millisecond of 24V 5 of open circuit voltage, number expresses: Maximum Cheng: 100 seconds resolution: 0. 001 seconds precision: 0.
