TD1870 Multi-Product Calibrator
暂无内容

Overview

Model TD1870, a wide-range, multi-value and high-precision calibrator with a built-in class 0。01 DC standard source and class 0。02 AC standard source, and also has the functions of AC/DC power output, phase adjustment, resistance simulation and pulse output。 Applied to calibrate 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

Features

● Electrical Parameters Output: Voltage is up to 1100 V, current is up to 22 A or 33 A at a frequency from 45 Hz to 1100 Hz.

● Resistance Simulation: Continuously variable range is from 2 Ω to 220 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.

● Excellent Human-Computer Interaction: Large LCD touch screen display, touch and button operation modes, easy for users to measure manually.

● 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.
