Overview

Model TD1880, a wide-range, multi-value and high-precision calibrator, can accurately output ultra-precision AC/DC voltage, current 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.

This calibrator complies with the following standards:

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

Functions

 Electrical Parameters Output: Voltage is up to 1100 V, current is up to 33 A at a frequency from 45 Hz to 100 kHz.

 Resistance Simulation: Continuously variable range is from 1 Ω to 1100 MΩ, pulse output range is from 1 Hz to 2 MHz.

 Value Output Mode: Standard source and output source modes, easy to calibrate both digital meters and analogue meters.

 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 11 types of TC and 11 types of RTD.

 Clamp Coil (Option): Match a 50 T clamp coil produces a maximum 1100 at equivalent current to calibrate clamp ammeters.

 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.

Features

 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.

 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.

 Large LCD touch screen display, touch and button operation modes, easy for users to measure manually.

 Support the calibration of the checked meters by semi-automatic or full-automatic, data management and report export. Connecting the instrument to a computer via RS-232 interface, easy to build computer automatic test system.
