Description
\u63cf\u8ff0
Each of the three displays has an extra digit compared with most portable magnetometers. Each is 4 \u00bd digits and displays in two ranges: \/- 1999.9 and \/- 199.99 milligauss. Update is three per second. Because the Earth’s field is typically about 500 milligauss, nine offset controls (three for each of X,Y,Z) allow you to add or subtract up to 600 milligauss with precision of .01 milligauss. Therefore, the Earth’s field can be subtracted out when required. If reading in the more sensitive 199.99 range, this field neutralization feature is often necessary, because the field is usually stronger than 200 milligauss.

The wide dynamic range of the displays (19,999 count; both polarities), along with the large range of offset ( \/- 600 milligauss) and high stability of the meter ( \/- .01 milligauss), allow for stable detection of small changes in a large background field. On the higher sensitivity range, changes of .01 milligauss can be reproducibly measured in up to \/- 800 milligauss of background field. On the lower sensitivity range, absolute field of .1 milligauss can be measured in up to \/- 1999.9 milligauss of background field.

The sensor is a 25 mm (one inch) cube at the end of cable that is normally four feet long, but other custom lengths are available. Each axis reads negative when pointing toward the south pole of a magnet and positive toward north.
