TD1880 Advanced High Precision Multifunction  Calibrator

TD1880 High-Precision Multi-Product CalibratorIntroduction TD1880, a wide-range, multi-value and high-precision calibrator, can accurately output ultra-precision AC/DC voltage, current, phase adjustment and power, and also has the functions of pulse output and simulating DC resistance, thermocouple (TC), thermal resistance (RTD) and capacitance. Applied to calibrate 6½ and below digits multimeters or other electrical measuring instruments.ReferenceJJG 124-2005 Verification Regulation of Amperemeters, Voltmeters, Wattmeters and Ohmmeters.JJF 1587-2016 Calibration Specification for MultimetersJJF 1284-2011 Calibration Specification of Calibrators for Electrical MetersJJF 1638-2017 Calibration specification of multifunctional standard sourceFeaturesElectrical Parameters Output: Voltage is up to 1100 V, current is up to 20.5 A at a frequency 10 Hz ~ 500 kHz.Resistance Simulation: Continuously variable range, 1 Ω ~ 1100 MΩ, pulse output range: 1 Hz ~ 2 MHz.The output current has high stability (the typical value is better than 10 ppm/h) and high accuracy (the typical value is 50 ppm/a), and its measurement accuracy is higher than the international similar products.Value Adjustment Method: Fixed-point, rotary encoder, step and potentiometer (option).Output Switch: The output can be turned on/off arbitrarily by one-touch operation.TC and RTD simulation: Support for simulation of up to 8 types of TC and 6 types of RTD.  Strong load capacity of AC, can drive various types of analogue meters and digital meters, so the applicable range of measured instruments is very wide. The protection of voltage and current sources ensures high reliability under complex conditions.Excellent Human-Computer Interaction: Large LCD touch screen display, touch and button operation modes, easy for users to measure manually.Transmitter Measurement (Option): Measure the secondary DC signal of the transmitters.Proprietary Software (Option): Support the calibration of the checked meters by semi-automatic or full-automatic, data management and report export.SpecificationAC Voltage OutputRangeResolutionFrequency (Hz)Accuracy (k = 2, ppm*RD +μV)Max.
