Cs-3 Manual - Scintrex

Getting StartedImportant:To minimize the static magnetic interference fromthe electronic components which are slightlymagnetic, the sensor head should be kept away fromthe electronics assembly by the full cable length.The actual measurement of the ambient magnetic field takes place inside theabsorption cell which has diameter 22mm, and the length 25mm. Theposition of the cell's centre is marked by a narrow groove, machined on theoutside of the plastic cylindrical housing. The adjacent wider grove isprovided to facilitate secure grip for the mounting clamps.The interconnecting cable exits at the right angle on the top end of the sensorhead. For properly orienting the sensor head as described in Chapter 3,“Orienting Your CS-3”, it is important to know the direction of the opticalaxis. In Figure 1 on page i, the direction of the optical axis is depicted inrelation to the outside mechanical features of the sensor head.The sensor head housing provides an air/water tight enclosure for the sensorcomponents, and it should not be opened. In addition, critical opticalcomponents inside the sensor head are carefully aligned in order to minimizethe orientation errors, and opening the sensor head by unqualified peoplemay upset the alignment.1- 6CS-3 Manual - part # 762701 Revision 1.0
