3.3 Setup The tension meter is delivered with a built-in rechargeable LiPo
battery, which has been charged at the factory. The tension meter can only be
switched on if the battery is still working, i.e. if the battery has enough
charge. If the instrument does not power up or if the battery level indicator
shows a low charge after power-up (Chapter 3.3.2), the battery needs to be
recharged.
To ensure maximum battery life, avoid discharging it completely or charging it
frequently for short periods. The battery should not be stored for an extended
period of time when empty. After a maximum storage period of one year, the
battery has to be recharged.

To insert the process material: – Push the thumbpiece as far as it will go in
the direction of the arrow to extend the
guide rollers. – Capture the process material with the filament guide (see
fig. 3.5.2). – Slowly release pressure on the thumbpiece until the guide
rollers return to their
original positions. It is important to assure that the process material runs
smoothly between the guide rollers and the measuring roller.
It is essential that the thumbpiece return slowly to its initial position. Any
uncontrolled snap-back may affect calibration and may also damage the
instrument.
To measure the process material: The display now shows the measured tension
values.
To remove the process material: – Push the thumbpiece as far as it will go in
the direction of the arrow. – With the guide rollers extended, move the
instrument away from the process material. – Slowly release pressure on the
thumbpiece until the outer rollers return to their
original positions.

3.5.3 Damping Feature to be used for tensions that vary strongly In the
Damping menu (chapter 3.4.1), you can specify a damping factor. Back in the
display mode, press the button to activate or deactivate the damping function.
This is recommended if the displayed values vary strongly. The factory setting
for the damping factor is 5. The average shown on the display is calculated as
follows: 5 old measured values + 4 new measured values 9 Damping can be
changed in 9 steps from 01 = low damping: 1 old measured value + 8 new
measured values 9 to 9 = high damping: 8 old measured values + 1 new measured
value 9
3.5.4 Using the alarm function Requirements: In the Material Setup menu, make
sure that the MIN and MAX limit values have been set for the material, that
will be used for the measurement. The alarms have to be enabled in the main
menu.
15
3.6 Creating a material characteristic
The tension meter has been calibrated on material 1 according our SCHMIDT
procedure for a vertical material path and cannot be deleted or overwritten.
The material and diameter is given in chapter 2. Factory calibrations using
customer supplied materials follow the same procedure. In this case, however,
the calibration on Schmidt material 1 is omitted. fig. 3.6.1 shows a measuring
setup for the calibration.
The SCHMIDT calibration has been preset in the factory and cannot be
overwritten. For these material characteristics, you can only change the name
and limit values.

Weight
Hang a weight which corresponds to the tension to be measured from the measured material, vertically, as shown here. Pay attention to the correct unit of measure.
fig. 3.6.1
16
3.6.2 Calibration procedure
Calibrations of the tension meter are performed according to the SCHMIDT
factory procedure using weights that correspond to 10 %, 50 %, and 90 % of the
measuring range. In 95 % of all industrial applications, the SCHMIDT
calibration has been proven to provide the best results. In particular, it is
suitable for comparative purposes. If the material to be measured differs
significantly from the SCHMIDT calibration material in material type,
diameter, rigidity, shape, etc., we recommend to perform a calibration using
customer-supplied material. In addition to the factory-preset material, you
can save up to 3 additional materials.
Calibration Units and Calibration Points – The device can be calibrated in
centinewton (cN) or gram (g). Although the unit of the
calibration weights has to correspond with the unit choosen in the menu
,,calibration” – For the calibration of the tension meter, three calibration
weights are used. For
example, if you select 10 %, 50 %, 90 % for the weights for the calibration
must correspond to 10 %, 50 % and 90 % of the measuring range. In this
example, you need the following weights for the ZEF-100: Calibration in
Newton: 10 cN, 50 cN and 90 cN Calibration in Gram: 10 g, 50 g, and 90 g
The measured values are displayed in the unit set in the ,,Settings” menu,
independent from the unit that was used to calibrate the material
characteristic. So that they are available when you verify the calibration
later or repeat the calibration after a factory reset.
e. g.
Material to be measured
Unit
Yarn
cN
Calibration points 5 %, 50 %, 90 %
To perform the calibration procedure – Select a material characteristic in the
material menu. Existing calibrations can be
overwritten (The factory calibration can not be overwritten). – Change to the
material setup menu and define the name and the limits of the material
characteristic. – In the ,,material-setup” menu, select Calibration.
While performing the calibration, the tension meter must be fixed in such a
way that the material to be measured runs smoothly between the guide rollers
and the measuring roller. The display gives detailed information on the
calibration.
17
3.6.2 Calibration procedure
Step 1: Set the calibration points and weights, e.g. in Newton using the
calibration points 10 %, 50 %, and 90 % of full scale Start: Select the Start
menu item. Alternative calibration points: 5 %, 45 %, 90 % 10 %, 45 %, 90 %
5 %, 50 %, 90 % 5 %, 25 %, 70 % We recommend to use the 10 %, 50 %, 90 %
setting for an initial calibration. If the measured values are not accurate
enough when you check the calibration, repeat the calibration using other
calibration points. We recommend that you align the middle of the tension
range to be measured with the middle calibration point. Step 2: Perform a zero
adjustment with the tension meter in its measuring position
Step 3: Calibrate calibration point 1 Insert material to be measured
Step 4: Calibrate calibration point 2
Step 5: Calibrate calibration point 3
Once you have completed the calibration, make sure to verify it as described
in chapter 3.6.3. In case of a large deviation, repeat the calibration or
select different calibration points.
18
3.6.3 Verifying the calibration
When verifying the calibration, make sure to select the same material,
calibration position and calibration points as used for creating the
associated material characteristic. Otherwise, the precision of the
measurements will not be sufficient. The tension meter has been calibrated on
material 1 according our SCHMIDT procedure for a vertical material path and
cannot be deleted or overwritten. The diameter and material is given in
chapter 2. Calibrations of the tension meter are performed according to the
SCHMIDT factory procedure using weights that correspond to 10 %, 50 % and 90 %
of the measuring range.

– Attach a weight vertically to the process materials that corresponds to the
tension to be measured (make sure to select the correct unit). The weight must
hang freely. (Always use a fresh portion of the material to be measured.)
– Insert the material as described in chapter 3.5.2.
Do not let the lever snap back as this could affect the calibration and damage
the instrument.
– Before verifying the calibration, move the instrument slowly up and down to
compensate for any mechanical friction losses and thus ensure repeatability of
the measurements.
– The tension value shown on the display should be equal to the mass of the
suspended weight.
If the verification of the calibration shows a deviation beyond the allowable
tolerance so that reliable operation is no longer possible, the instrument
needs to be re-calibrated or returned to the factory for repair.

calibration accuracy verification depends on several different factors:
Operating time and load of the SCHMIDT tension meter Tolerance band defined by
the customer Changes to the tolerance band compared to previous calibrations
Therefore, the interval between verifications of calibration must be
determined by the users Quality Assurance Department, based on the users
experience. Assuming normal operating time and load as well as careful
handling of the tension meter, we recommend a verification interval of one
year. 21
