The device must not be operated in explosion hazard areas and must
not come into contact with aggressive substances.
Tensions that exceed the measuring range of the device by more than
100% may cause a permanent deformation of the measuring spring
and must be avoided under any circumstances.

1.0 INTRODUCTION
The CHECK•LINE®model ODT Tension Meter accurately measures running line
tensions on a wide variety of yarns, fibers, wires, etc. It's designed for fixed mounting
and continuous tension measurement.Threaded mounting holes are provided on the
back side and edge of the housing.
2.0 MOUNTING PROCEDURE
Two mounting holes are provided for fastening the tensionmeter on site, see below.

3.0 OPERATING PROCEDURE
3.1 Inserting the material to be measured
Carefully thread the material to be measured through the measuring roller
and roller guides, as shown below. It is important to ensure that the measured
material runs smoothly through the roller.
To avoid damage do not move the center roller by hand
using force.
3.2 Setting the Maximum Tension Detector (optional)
Need copy?
Are there any other steps that need to be taken
before the gauge begins operating?

* Suitable for 95% of applications. PA = Polyamide Monofilament. If the material
to be measured differs significantly from the factory calibration material in diameter,
rigidity, shape, etc., we recommend calibration using customer material. For this
purpose, a material sample of about 5 m should be supplied. International unit for
tension force: 1 cN = 1.02 g = 0.01 N

4.0 VERIFICATION OF THE ODT CALIBRATION
All tension meters are calibrated according the factory procedure using standard
materials—such as polyamide monofilament (PA)—. The filament sizes are noted in
Section 7 on page 6. Any difference in process material size and rigidity from the
standard material may cause a deviation of the accuracy.
NOTE: In 95% of all industrial applications the factory calibration has proven
to provide the best results and is used for comparative purposes. If the process
material differs significant in size, rigidity and shape we recommend special
calibration using customer`s sample. For this purpose a material sample 5 m long
should be supplied.
Verification Procedure
1. Suspend a known weight that corresponds to the tension to be measured (pay
attention to the correct unit of measure) from the process material, vertically, as
shown below (Always use a fresh portion of the material to be measured).
2. Before the final check, move the process material slowly up and down to
compensate any friction caused by the instrument and thus ensure the repeatability.
3 The tension value should be equal to the value of the suspended weight.
NOTE: If this procedure shows a deviation beyond the allowable tolerance and
a reliable operation is no longer allowed, the instrument has to be recalibrated or
repaired. For recalibration, return the tension meter to the factory.

5.0 MAINTENANCE
5.1 Calibration Verification Intervals
Finding the right frequency of calibration accuracy verification depends on several different factors:
• Operating time and load of the tension meter
• Tolerance band defined by the customer
• Changes of the tolerance band compared to previous verifications of
calibration
Therefore, the interval between verifications must be determined by the user`s
Quality Assurance Department based on the user`s experience. Assuming normal
operating time and load as well as careful handling of the tensionmeter, we
recommend a verification interval of 1 year.
5.2 Rollers
You should regularly inspect the rollers to assure that they are running easily and
smoothly. You can replace the rollers yourself, as necessary. When ordering
spare rollers, please indicate the tension meter model and the serial number
(on the rear side of the tension meter).
Example of ordering of spare rollers
Model: ODT-20 (on the rear of the tension meter)
Serial number: 230 - 888888 (on the rear of the tension meter)
Standard rollers: Order number R12013
5.3 Cleaning
When cleaning the unit, do not use any aggressive solvents, such as
trichloroethylene or similar chemicals. No warranty or liability shall
be accepted for damage resulting from improper cleaning.
