Test Procedure:

1.The first step is to select the method/mode to be chosen. 

2.The yarn has to be clamped between 2 clamps.

3.‘S’ or ‘Z’ key has to be selected depending upon twist direction.

4.The stopper at the left front side of the Automatic Twist Tester has to be set at approx 50% of expected elongation.

5.The motor has to be started by pressing the ‘START’ key.

6.The motor will start untwisting the yarn and LCD display will start counting.

 

Salient Features:

1.Latest microprocessor based equipment used to determine the twist per inch/cm.

2.Specially designed for single yarn, double yarn & open-end yarns.

3.A special sensor for zero setting.

4.Special tensioning device provided to give tension to the yarn while testing.

5.Totally programmable unit.

6.User-friendly control panel, which guides the operator to undertake all steps for testing.

7.Smooth precision-engineered auto mechanism.

8.1 to 50gms weight supplied to give proper tension during testing.

9.Digital control panel with 16-character, 4 line LCD display.
