A new system for precise measurements of the multipole components of the APS magnetic insertion devices is described. The stretched coil is used to measure magnetic field integrals. Hardware includes number of servo motors to move (translate or rotate) the coil and fast data acquisition board to measure the coil signal. PC under Linux is used as a control workstation. User interface is written as a Tcl/tk script, hardware access from the script is done through shared C-library. The description of the hardware system and control program are given.
