How to measure the thread tension with a spring scale

A spring scale, e.g. from the company Pesola, helps to quickly, precisely and easily find out the thread tension of Dürkopp Adler sewing machines and sewing automats (see pictures).

The recommended thread tensions can be adjusted optimally – no matter if electronic or mechanic thread tension. This saves valuable time for adjustment and trials.
