The standard source is mainly used for verification and calibration of DC AC level 0.1 and below level 0.2 all kinds of instrument and meter, is the ideal tool standard. The following Xiaobian introduce main characteristics of multi function AC / DC standard source.
1, multi function, high accuracy, high power, and can be widely used in the test of various frequency meter.
2, the output voltage, current, phase, power factor and frequency are the soft start range can be switched automatically or manually, the impact load is small. Rated output power high voltage.
3, multi output parameters, scope of application: can not only complete verification of digital and analog indication multimeter, can also test AC and DC voltage, current and power table, AC voltmeter, ammeter, useful power meter, useless power meter, phase meter, power factor meter, frequency meter, electrical energy table and single intersection, AC transducer, including almost all single intersection DC instrument.
4, display function and easy to use: LCD large screen display, not only can show the relative error and absolute error, but also according to the input index number to turn into the index, according to the input full degree display reference error. In addition to the basic output and error output, the power factor, active power, reactive power and other power parameters can also be displayed. Input the number keys and with the use of rotary encoder, and a full and clear function, adjust the output is extremely convenient.
5, perfect protection function: even if the wrong operation does not damage the calibrator and the detected meter, current and voltage are provided with overvoltage and overcurrent double protection, high reliability.
6, with external calibration function, can be used to calibrate all the parameters can be maintained after calibration accuracy.
7, with RS232 interface, and computer connected to form a automatic test system (optional), multiple management work in testing data processing, certificate printing and file management.
