PERATING ROCEDURE
NOTE: To facilitate easy use, the MKM handle can be attached to the top or
bottom of the gauge body (see diagram on page 2).
1. Depending on the orientation of use, plug in the jack plug of the handle at
either of the two jack sockets provided on the sides of the tension meter.
2. Thread the process material through the guide eye, the outer rollers
and the measuring roller. Then wind the process material around the
take-up wheel two or three times.
3. Press the motor switch to start measuring. The scale now shows the measured
tension values. If the scale does not show a reading, the process material may
be threaded throug the rollers incorrectly. Not the proper position of the
process material in the diagram below and retry.

ERIFYING THE ALIBRATION
All tension meters are calibrated with standard materials—such as polyamide
monofilament (PA)— according the factory procedure. Filament sizes are noted
in Section 5.2.
NOTE: Any difference in process material size and rigidity from the standard
material may cause a deviation of the accuracy.
In 95% of all industrial applications the factory calibration has been proven to
provide the best results and is used for comparative purposes.
If the process material differs significant in size, rigidity and shape we recom-
mend special calibration using customer`s sample. For this purpose a material
sample of 5 meters in length should be supplied.
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 in the figure. 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.
If this procedure shows a deviation beyond the allowable tolerance and
reliable operation is no longer possible, the instrument must be returned to
the factory for recalibration or repair.
