Shanghai Zhengyang ZY2508 DC low resistance meter calibrator

The ZY2508 DC low resistance meter calibrator has a total of 200 resistance readings within the adjustment range of 1 µ Ω to 20K Ω, with a large coverage area and an accuracy level of 0.01 in accordance with the "Low Resistance Meter Verification Regulations". Ideal equipment for verifying low value DC resistance meters, micro ohmmeters, and ohmmeters. Used for the calibration of low value resistance meters, digital micro ohmmeters, and other resistance meters.

ZY2508Type is a precision measuring tool for low resistance measuring instruments, which can be used to measure current/Various digital and analog DC low value resistance meters based on voltage measurement principles are used as standards; It is an ideal equipment for DC low value resistance meter manufacturing enterprises, laboratories, and measurement units. Instruments are shared10A range, each range has20A resistance reading, in1μ Omega20kInstruments within the Ω adjustment range are shared200A resistance indication with an accuracy level of0.01Grade. Can meet the requirements of the low value resistance meter calibration regulations for calibration points. The key resistance components of the instrument are made of high-quality manganese copper alloy material, which has undergone strict processing and long-term aging treatment. The instrument also uses precision instrument switches from Fangke Company, making it highly accurate, with a small temperature coefficient and good stability. The circuit structure adopts a combination of physical resistance and equivalent resistance, and compared with conventional standards, the instrument has the characteristics of wide range, small size, light weight, and easy use.
