1.00 INTRODUCTION

Specifications

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.

* When the units of measure are changed to grams, the “gf” indicator will
momentarily flash on and then turn off. Otherwise the “lb.” or “oz” indicators
will be shown.

• Starts/Stops scanning for Max/Min/Peak values. (Standard Memory)

• Starts/Stops automatic recording of values into memory (Continuous Data Logging Model).

• Loads displayed value into memory (On-Demand Data Logging Model).

• Enters Recall Mode to review statistics and recorded Data.

• In recall mode, changes display from LAST ➔ MAX ➔ MIN ➔ PEAK ➔ LAST ➔ MAX etc.

• When in Data Logging Mode: changes display from LAST ➔ MAX ➔ MIN ➔ PEAK.
➔ AVERAGE ➔ STANDARD DEVIATION➔ DATA #1 ➔DATA #2 ➔ DATA #3 etc.

• Turns power on.

• Turns power off if pressed and held for 5 or more seconds.

• Exits from Recall Mode when reviewing data.

• Clears all data in Basic Memory (“CCCC” momentarily shown on display).

• Zeros gauge (“Tare”) for use in any orientation (“Gravity Correction”).

*

• Changes units of measure from grams (or Kg) to pounds (or ounces) and back again
each time this key combination is pressed.

Special Calibration

If the standard Factory Calibration and
the Field Calibration Adjustment does not
provide the desired accuracy, a Special
Calibration can be ordered. A l0' sample
of the process material must be provided
for calibration purposes.

8.40 On-Line Mounting Holes

The DTMB is supplied with two threaded
holes for on-line mounting in a fixed posi­tion when performing measurements over
an extended period.
