Product Description GDDO-20T Calibrator for AC Sampling Device and Transmitters General Information GDDO-20T Calibrator for AC Sampling and Transmitters takes DSP technology and 16 digit high speed A/D converter as core technology in AC sampler.It has the features of high precision, good reliability, convenient to use. Reference standard GB/T13729-92: General Specification for Remote Terminal UnitDL/T630-1997: Technical Requirement for RTU with AC Electrical Quantities Input, Discrete SamplingJJG126-95: Verification Regulation of Measuring Transducers for Converting AC Electrical Quantities into DC Electrical QuantitiesQ/GDW1899-2013: Verification Regulation Calibration Specification of AC Sampling Electrical Measuring EquipmentJJG124-2005: Verification Regulation of Amperemeters, Voltmeters, Wattmeters and OhmmetersJJG 596-1999JJG 307-2006 Features It can check the basic errors of various power frequency meters (voltmeter, ammeter, power meter, frequency meter, power factor meter, phase meter) and the changes caused by the influence of voltage, current, waveform, power factor under manual or semi-auto mode.It can check the basic error of AC sampling device and electrical measurement transmitter (voltage transmitter, current transmitter, power transmitter, frequency transmitter, power factor transmitter, electrical energy transmitter) as well as the changes caused by influence of voltage, current, waveform and power factor under auto or semi-auto mode.The distortion wave with 2nd~31th harmonics can be generated in the power supply, and the number, order, amplitude and the phase of harmonics on the fundamental wave can be programmed.The working frequency band of power amplifier is 40Hz ~1kHz, with good linearity. The current amplifier is a constant current source and the voltage amplifier is a constant voltage source. Because of its light weight, the device is more suitable for field calibration.The RS-232 interface is provided. Through the upper computer software (optional), the device can be controlled by the computer for automatic or manual inspection, and results are processed and managed.It is equipped with large capacity non-volatile memory, which can store 300 pcs of initial data of the tested instrument for reference and uploading.The electricity meter can be calibrated through load point or optional point detection.
