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 exten-
ded period of time when empty. After a maximum storage period of one year,
the battery has to be recharged.
In the display mode, the different displays can be switched through by pressing
simultaneously and

(100 V - 240 V).
HANS SCHMIDT & Co. GmbH provides no warranty or liability for any
damage resulting from the use of AC adapters from other manufacturers.
To charge the battery, connect the cable of the AC adapter to the power connector.
When the battery is fully charged, the battery level indicator will be shown full .
The charging time is approx. 3 ½ hours (using the AC adapter).
Battery overcharging is not possible
3.3.2 Switching the tension meter on
Press and hold the button (for approx. 1 sec.) until the DISPLAY shows the measu-
ring range, the software and hardware versions, e.g. SW 1.0, and then “0”.

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

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 dia-
meter 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 omit-
ted. 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.
3.6.1 Setup for calibration
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.

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.
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.
Material to be
measured Unit Calibration points
Yarn cN 5 %, 50 %, 90 %
e. g.

18
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 calibra-
tion. 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.
3.6.2 Calibration procedure
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.

19
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 ma-
terial 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.
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 compen-
sate for any mechanical friction losses and thus ensure repeatability of the measure-
ments.
- 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.
- 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.
