Product description

Product Introduction

　　This product is a high-power DC standard resistor simulated by electronic circuitry using DC current comparator technology, solving the problem of power limitations in physical resistors. It is suitable for calibrating loop resistance testers, DC resistance testers, and other DC low-resistance instruments. Reference standards: JJG 1052-2009 "Calibration Procedures for Loop Resistance Testers and DC Resistance Testers", DL/T967-2005 "Calibration Procedures for Loop Resistance Testers and Fast DC Resistance Testers". Resistance error, linearity error, and stability error can be tested according to the procedures.

Main Features

　　◆ Features higher sensitivity, more adjustment digits, lower noise, higher accuracy, strong anti-misoperation capability, ease of use, and flexible operation;

　　◆ The device has good protection and high reliability, with a self-calibration function to ensure periodic inspection qualification;

　　◆ The resistance is continuously adjustable under power.
