TD1455 Equivalent Resistance Standard
暂无内容

Overview

Model TD1455, an apparatus that can accurately simulate AC and DC standard resistance. The DC resistance range is from 1.000 0 μΩ to 200.000 Ω, the AC resistance range is from 30.000 μΩ to 150.000 Ω, and the optional accuracy classes are 0.02 and 0.05. Applied to calibrate loop resistance testers, earth-continuity testers or other AC/DC low resistance apparatuses.

Meet the requirements of following regulations:

JJG 1052-2009 Verification Regulation of Loop Resistance Testers and DC Resistance Meters

 DL/T 967-2005 Verification Regulation of Loop Resistance Tester and DC Resistance High-Speed Tester

 JJG 984-2004 Verification Regulation of Earth-Continuity Testers

 GB/T 28030-2011 Earth Continuity Tester

The following tests are performed according to the requirements of regulations: resistance error, linear error, stability error, operating current error, operating current overshoot measurement, warning settable error and test current settable error。

Features

 Full digital adjustment and programming interface, the resolution is as low as 2 nΩ which is greatly better than physical resistors.

 Compared with the traditional physical standard resistance box, there is no error effect caused by the residual resistance and contact resistance from bandswitch, and avoids the resistance change caused by overload.

 Compared with electrical analog resistance, it has the features of higher sensitivity, more variable digits, lower noise, higher accuracy, intuitive display, preventing incorrect operation and easier operation.

 Directly measure AC or DC current with a wide range of 0.01 A to 600 A, and fully-automatically switch on all ranges.

 It can also be used as a best ammeter with the functions of DC ripple measurement, frequency measurement, harmonic measurement, data statistics and analysis, stability test, etc.

 The current measurement channel has the waveform display function for measuring the operating current overshoot of measured meters.

 HD LCD touch screen can display the input current, output voltage, equivalent resistance and the error of measured meters at the same time.

 Good protection, high reliability and self-calibration function.
