this group is ISH-2, ISH-3, ISH-4, ISH-4T, design by
I.V.Shevchenko, IK-2, IT-200, UMI-25, ZI-1M and I-7.
The main part of mechanical devices - rotating frame, axis
of which coincides with the main inclinometer axises (Fig.5.2).
The frame center of gravity is offset so that it plane always settles
perpendicular to the plane of well warping. In the frame contains
sensors of azimuth and warping angle of wells.
