Abstract
A MOA resistive current on-line measuring instrument using the chip computer is described.Complete comparison between this one and type LCD-4 one is made through the experiments in the lab and in the field.Results show that it is distinctive in aspects of signal sampling
processing and anti-EM-interference.The instrument has high relibility and good stability
and can reflect sensitively higher harmonic components in MOA.Its accuracy rivals type LCD-4 instrument.It’s suitable to common MOA users.
