1.0 OVERVIEW & OPERATING PRINCIPLE ZD2 and ZF2 Tension Meters are hand-held, mechanical instruments which accurately measure the running as well as static tensions of a wide variety of process materials including yarns, fibers, wires and optical fibers. They employ the 3-roller principle for tension measurement where the outer two reference guide rollers remain fixed during measurement to establish a wrap angle over the middle sensing roller.

3.0 QUICK START INSTRUCTIONS 5.0 OPTIONS 1. Prior to engaging the material under test, part the 3-roller system by pressing and holding the Trigger. 5.1 High-Speed Guide Rollers 2. Keeping the outer rollers extended, bring the instrument behind or under the filament and move it so that the Filament Guide bars contact the process material. ZF2 guide roller assemblies are rated for 900 m/min., maximum. High-speed roller assemblies are optionally available: 3.
determination is best made by the user’s Quality Assurance Department based on the user’s experience. However, a quick calibration check near the anticipated process tension levels should be done to confirm the integrity of the instrument, as follows: 1. At the beginning of each work session 2. Every time a unit is dropped 3. Whenever process readings seem to be out of tolerance for no apparent reason The quick check can be made with a simple load stand, as shown in 4.
4.1 Calibration with Factory Standard Filaments 4.2 Special Calibration All ZF2 and ZD2 Tension Meters are calibrated with laboratory weights suspended from factory Standard nylon monofilament sizes, as noted in the table below. Any difference in process material size and rigidity from the Standard materials may result in some error.
