The electronic twist-tester 61 is an advanced testing instrument able to determine the twistings number of yarns in S or Z

Manufactured by Branca Idealair and designed to determine the exact number of twist for single e.g. spun or filament yarns, plied, cabled, multi-level, Open-End yarns and other yarns typology in accordance to national and International Standards.

The electronic twist-tester 61S is compliance to reference standards UNI 9069, UNI EN ISO 2060, ISO 2061, ASTM D-1423, ASTM D-1422

The electronic twist tester 61 is designed to determine the twists number with high accuracy of +/- 0,1 turn, suitable both for single, double and multi-level yarns with variable lengths from 0 to 50 cm in standard models or up to 1 or 2 mt for special ones.

The electronic twist tester 61S is a user friendly device for all operators thanks to the comfortable 5" display with touch screen that allows operators to choose the correct test methods for yarns available in an advanced interface as e.g. untwist-retwist operations and other procedures already included in the standard model as indicated here below:
- Single yarn test, untwist-retwist suitable for single yarn;
- Direct counting method, only yarn untwist;
- Dual yarn test, separation of plied yarns (2 ends yarn) + DUAL F2, for determination of turns no. of last yarn end;
- Schutz method, according to the 2nd Appendix New “double test check” worked out by Messrs. M.KUENY, H.LE CHATELIER and R.A. SCHUTZ;
- Manual test, motor control set directly by the operator with turns count reading;

supplementary test methods are implemented only in the PRO model :
- Multi levels yarn test, suitable to determine the turns no. of plied yarns up to 5 levels;
- Guided analyses, direct analysis on Single, Direct Counting, Dual, Multi-level yarns following the operator step by step during all test procedure;

The test bullettin is printed from the ASCII printer supplied on request, where the operator can input data and notes as additional data, e.g.:
- Company;
- Instrument no.;
- Tension applied in grams during the test;
- Notes;

Test report includes also info about:
- Direction of twist (SZ or ZS);
- Sample length, expressed in cm or inches;
- Saved memory up to 20 results per test method;

Statistical evaluations:
- Minimum;
- Maximum;
- Average;
- Delta (Max-min);
- Coefficient of Variation (CV%);
- Standard Deviation (ST.Dev%);

Stored data can be expressed both in tpm (twist per meter) or in tpi (twist per inch) always chosen by the operator; the measure unit chosen are shown on test report;

During the test the HMI touch screen shows data and evaluation data, e.g.:

Motor speed in rpm;

Number of twist on real time;

Test index (1..20);

Direction of twist (S/Z or Z/S);

Operation commands e.g. start, stop, repeat, etc.);

For standardmodels:

20 results available for single yarn test;

20 results available for direct counting method;

20 results available for dual yarn test;

20 results available for Schutz method;

For special models:

20 results available for multi levels yarn test;

TWIST4.0: the application software for PC through USB serial communication allows to do automatic statistical evaluations on test results, generation of trend graphs, macro plugins and math formulas;
