Supports DLT-645(2007)communication protocol,and can complete demand indication error,demand period error, time switching error, rate period energy indication error and other multi-function test projects.
Constant temperature crystal oscillator,which is able to verifies the daily time error of electric energy meter.
Fantastic panels screen and wiring arrangement.The front and rear panel are designed to be easy-operating
It can be used as harmonic power output equipment,which is able to equipment,which is able to create stable harmonic output.
Testing mode: active power, reactive power
Meter under testing:3P4W, 3P3W,1P2W
The calibrator is combined by a power source and calibration electronic instrument with wide current and voltage output range.
Starting test and creeping test are supported Test data can be managed by computer via LAN interface
YC99T not only can be operated by equipment but also can be controlled by PC
Calibrate energy meters automatically,which including items, such as,preheating,starting,creeping,error, influence, quantity test etc.Primary Competitive Advantages:
Easy operation
Strong and stable harmonic power source output
Multiple-type of active and reactive energy meter test
