All Eltex thread tension monitors are calibrated before delivery. When we calibrate a new ETM we check that the unit is fulfilling the specification mentioned in the documentation of the ETM unit. When we re-calibrate we check that the unit is fulfilling the same specification as when it was once produced.
ETM units that are sent for recalibration / repair are calibrated at our sales / research / service office in Osby, Sweden. Please send units that needs calibration to below address and give us a notice in advance to check for availability. During normal circumstances the handling time will be one working week from arrival to Eltex.
