NR1800 series high-power standard resistors

Category

Comprehensive test part

This product is a DC high-power standard resistance that is simulated by the electronic circuit of DC current comparator technology, which solves the problem that the physical resistance is limited by power. It is suitable for calibrating loop resistance tester, DC resistance tester, and other DC low resistance instruments. Reference standard: JJG 1052-2009 "Verification Regulations for Loop Resistance Testers and Direct Resistance Testers", DL/T967-2005 "Verification Regulations for Loop Resistance Testers and DC Resistance Quick Testers". Test items such as resistance error, linearity error, stability error, etc. can be completed according to regulations.

Product Description

　　This product is a DC high-power standard resistor that is simulated by the electronic circuit of DC current comparator technology, which solves the problem of power limitation of physical resistance. It is suitable for calibrating loop resistance tester, DC resistance tester, and other DC low resistance instruments. Reference standard: JJG 1052-2009 "Verification Regulations for Loop Resistance Testers and Direct Resistance Testers", DL/T967-2005 "Verification Regulations for Loop Resistance Testers and DC Resistance Quick Testers". Test items such as resistance error, linearity error, stability error, etc. can be completed according to regulations.

Main Feature

　　◆ It has the characteristics of higher sensitivity, more adjustment digits, lower noise, higher accuracy, strong anti-misoperation ability, convenient use, flexible operation, etc.;

　　◆ The device has good protection and high reliability, with self-calibration function to ensure that the periodic verification is qualified;

　　◆ The resistance is continuously charged and adjustable.
