Product features: l Instrument has safe and convenient operation, all microcomputer device, built-in imported high-performance CPU, high reliability, Don’t need artificial contact measured equipmentafters after setting test values according to the interface suggestion. Instruments will automatically complete the test, let the test person away from high voltage circuit, to ensure the security of person; l The output capacity is big, maximum output voltage could be 1000V on Volt-ampere characteristics test, maximum current could be 600A on transformer ratios tester, instrument output capacity is 5KVA; l Optional accessories including external booster device, external current power,external voltage regulator,and external booster device maximum voltage could be 2000V,3A, external current power could be 1000A, external voltage regulator maximum output could be 1500V,20A.When adopt external booster device,do Volt-ampere characteristics test of current transformer can reach 500KV level,1A; l With big screen 320*240 dot matrix characters graphic interface, after test it can directly display volt-ampere characteristics curve,and tne graphics is clear,beautiful and easy to analysis. May at any time print curve and test results as it bringing micro printer; l Instrument use rotating mouse as the input device,operation is simple and service life is long; l Instrument built-in Flash memory, data will not lost after storage when power lost.Completed field test,could view and print test result indoors; l Instrument with RS232 communication interface,could use interface connect with computer, achieve communication with PC, test person use computer to control instrument and convey test result. Instrument with PC application is powerful,can save and print the test result. And test data can be derived form memory to be excel document and edit it; l Instrument power can realize adaptive power supply at AC220V or AC380V. ,
