A yarn processing system including a feeding device, a power loom, a controllable yarn tension device which is situated downstream from the feeding device, and a tensiometer which supplies a signal that represents the yarn tension and which is arranged downstream from the yarn tension device. The tensiometer includes a separating device which can be adjusted between a passive position and a separating position and with which a temporary separation between the tensiometer and the weft yarn can be effected in order to generate a zero yarn tension signal for a signal analysis device. In addition, the weft yarn is temporarily separated from the tensiometer probe during the interval between successive insertion operations, and a calibration is carried out for a future control operation by using the zero yarn tension signal.
