2021B Single-phase On-site Calibrator For Energy Meter
Introduction
The 2021B single-phase on-site calibrator for energy meter adopts new microprocessor technology and digital signal processing technology, which has the characteristics of novel design, simple structure, small size, light weight, multiple functions, and convenient use. The instrument comes with a high-precision virtual load and has a soft start function when powered on by the power supply. The operator can operate it when the user has no load under the syetem, the error and other
state parameters of single-phase energy meters can be quickly, accurately, and safely detected without power outage or meter disassembly.
