All tension meters are calibrated with standard material—such as polyamide-
monofilament (PA)—according to the Electromatic factory procedure; the
material path is vertical. 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 Electromatic calibration has been
proven to provide the best results and is used for comparative purposes.
If required, you can also operate the sensors with a material path other than
vertical. Should the process material differ significantly from the
Electromatic calibration material in size, rigidity and shape, we recommend
special calibration using customer-supplied material. In the case of a material
path other than vertical or special calibration using customer-supplied
material, you need to carry out static zero and gain adjustment once again
as described in Sections 6.1 and 6.2.
When threading the process material through the rollers, follow the
material path symbol on the front of the sensor. If a force is applied
to the middle sensor roller in the incorrect direction,
damage could result.
NOTE: Since zero and gain adjustments are always performed statically, the
display values may differ under dynamic load.

3. Hang a weight that corresponds to the tension to be measured (pay
attention to the correct unit of measure) from the measured material,
vertically, as shown in the figure above (Always use a fresh portion
of the material to be measured.)
The tension value on the digital display should be equal to the
value of the suspended weight.
If this procedure shows a deviation beyond the allowable tolerance and
a reliable operation is no longer allowed, the instrument has to be
readjusted, following the directions in Section 6.3.
