Introduction

  • 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.


Reference

  • JJG 124-2005 Verification Regulation of Amperemeters, Voltmeters, Wattmeters and Ohmmeters.

  • JJF 1587-2016 Calibration Specification for Multimeters

  • JJF 1284-2011 Calibration Specification of Calibrators for Electrical Meters

  • JJF 1638-2017 Calibration specification of multifunctional standard source


Features

  • Electrical Parameters Output: Voltage is up to 1100 V, current is up to 30 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.
