1.00INTRODUCTION

The CHECK¥LINE¨ DTMB Digital Tension Meter is a hand-held device which accurately measures the running as well as static tensions of a wide variety of process materials including yarns, fibers, wires, optical fibers, etc. It employs the "three-roller principle" of tension measurement where the outer two reference rollers are fixed to create a known angle of wrap over the middle sensing roller. The middle roller is part of a precision strain gauge sensing system which accurately measures the resulting force on the roller. This value is converted into a highly accurate and repeatable tension value using proprietary computer calibration formulas which correct for different material diameters, gravity and other critical parameters. The DTMB is powered by four AA batteries and is supplied in a rugged, die-cast aluminum housing.

The DTMB takes 62 tension measurements per second and displays the average of these measurements over a user-selected interval of 0.5, 1, 2 or 4 seconds, the Display Update Rate. This permits the user to determine the extent of averaging (or damping) required to "stabilize" the tension readings, making them much easier to read and eliminating the undesirable "bouncing needle" condition found on most mechanical tension meters. To set or change the Display Update Rate, refer to Configuring Dip Switch Settings, Section 5.30.

A built-in memory system is provided which permits storage of the maximum, minimum and peak values occurring during a measuring interval. These values can be recalled to the display for viewing.
