Instrument of Agilent 4284A accurate LCR is the good in quality and cheap in price instrument that is used at component and material to measure. It passes the test means that provides accurate, high handling capacity to improve the quality of component. 20Hz measures frequency limits and admirable test signal widely to 1MHz, the most current test level is accorded with to be like IEC/MIL standard when making 4284A is testing cell (international Electrotechnical Committee or American military standard) , and below the working requirement that the job uses in imitate place. Receiving inspection still is in no matter studying development, production, quality,assuring, 4284A can satisfy all LCR to gauge a demand.

Monitor:   
LCD lattice shows: Indicate the value that be measured, control a setting, compare the limit and court decision, list scanning is expressed, check information and signal directive oneself
Correction function open a way / short circuit error is 0: Eliminate what cause by impedance of parasitism of stray of test clamping apparatus to measure an error
Receive load: Use already school parts of an apparatus is improved as reference measure precision
List scanning function can is opposite at most 10 frequency or process designing of test signal n. Can undertake second test or order check sheet, should install mount options 001 when, still can undertake dc bias voltage checks
Comparator
 10 storehouses room (Ten-bin) classification is used at measuring parameter. Input / output is used at measuring parameter
