Digital Video Concepts, Methods, and Metricsield, a data acquisition system, two cassette recorders, an analogue chart recorder, a calendar clock, and a telex. The analogue and digital input data are sampled at 10 sec intervals, averaged over a minute, and recorded on a magnetic tape cassette. The computed hourly and daily mean values and the

Lixin Fan,Chee Seng Chan,Qiang Yangs of the geomagnetic component on paper tape. It has a range of outputs including analogue recording of the field variations which can be measured in the range 0–1999.9 nT with a sensitivity of 0.1 nT. After a running in period of some months the standard deviation of baseline values is in the range

A Taxonomy of Whistleblowing Platforms,Geomagnetic Observatory. The instrument is working with the use of a combination of the addition and compensation methods to directly measure absolute values of field components. A sophisticated equipment for the current generation and control is necessary to maintain the current flowing in the Helm
