1.0 OPERATION

1.1 Fastening the MK Tensionmeter

Two mounting holes are provided for fastening the tensionmeter on site. For
the mounting hole dimension, see the figure below.

1.2 Inserting the material to be measured

Thread the material to be measured
carefully through the measuring roller
and roller guides as shown in the figure
at right. it is important to ensure that
the material runs smoothly through
the roller guides and the measuring roller.

To avoid damage, do
not move the center
roller using force.

You can now read the measured

tension on the scale.

1.3 Air Damping (Optional Accessory code A)

The measuring system of the MK can be factory-equipped with a dashpot.
This dashpot makes it possible to absorb approximately 50% of the pointer
oscillations. We recommend application of the dashpot in the case of high
tension fluctuations (spooling or winding). The setting of the dashpot has to
be tuned to the local conditions by experimenting.

** Suitable for 95% of applications. PA = Polyamide Monofilament If the
material to be measured differs significantly from the SCHMIDT 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
