Requirements
:
- Switch the tension meter on (chapter 3.3)
- Define the required tension meter settings (chapter 3.4)
- Select the desired material characteristic (chapter 3.4.1)
- Set the material thickness compensator (chapter 3.5.1), if equipped
- Bring the tension meter into the desired measuring position and carry out a zero
adjustment as described in chapter 3.5.2, if required.
3.5.1 Material Thickness Compensator
(only for devices with thumbwheel)
The 3-roller-system for tension measurement relies on the
displacement of the middle roller (measuring roller) to give an
indication of the line tension. As the material thickness
changes, there will be a change in the tension reading, even
when the line tension has not changed. To compensate for
this effect, high-range instruments are usually equipped, as
necessary, with a material thickness compensator, which
automatically shifts the outer rollers. To adapt the tension
meter to the diameter of the material to be measured, push
the thumbpiece into the adjustment position “0” (chapter
3.5.3) and pull the thumbwheel of the material thickness
compensator backward to the adjustment position
(Fig. 3.5.1). Turn it clockwise or anti-clockwise until the
desired diameter, such as
, appears in the upper right part of the display. Then
push the thumbwheel of the material thickness compensator back to the measurement
position (Fig. 3.5.1). If you set a diameter that has not been calibrated for the selected
material characteristic, the set diameter is displayed with a black background color, e.g.
. The tension meter can be used anyhow, but please note, that depending on the
material to be measured, slight deviations in the measured values might occur.
If you rotate the thumbwheel while the thumbpiece is in position 2
(measuring position fig 3.4), the reading on the display will be updated, but
the value will not be used by the instrument to determine the tension – false
measurement!
The maximum material thickness you can set is 2.50 mm. Setting a higher
diameter can damage the tension meter.

3.4.3 Factory reset
A factory reset resets the tension meter to its original manufacturer settings. This proce-
dure will delete all settings, including any customer-defined material characteristics
(calibrations); the factory calibration, however, will be kept.
Customer calibrations will be deleted.
