The individual models of the DT Series are also available with the following
modifications (customized versions):

- Special tension ranges

- Customized measuring head width for applications with limited access space

- Customized distance between the two outside guide rollers to minimize
deflection of fragile material

International unit of tensile force: 1 cN = 1.02 g = 0.01 N, 1 daN = 1.02 kg = 10.0 N

* Depending on model, either width of filament guide or outer distance between
outside guide rollers.
** Suitable for 95 % of all applications. PA = Polyamide Monofilament. If the material to be
measured differs significant from the SCHMIDT calibration material in diameter, rigidity,
shape, etc., we recommend calibration using customer supplied material. Instruments
with calibration on customer sample are not adjusted and calibrated on material 1 and 2.

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 only one bar

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 a exten­ded period of time when empty. After a maximum storage period of one year,
the battery has to be recharged.

3.3.1 Charging the Battery

The battery can only be charged at a temperature between +5 °C
and +45 °C.
Before you connect the AC adapter, verify that the supply voltage is correct
(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 low USB output.
The battery can also be charged by connecting the USB cable to a PC.
When the battery is fully charged, the battery level indicator will show 5 bars

.

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
measuring range, the software and hardware versions, e.g. E 1.0, and then “0”.
During startup, the tension meter performs an automatic zero adjustment (see chapter

3.5.2).
Holding the

button makes the display freeze so that you can read the measuring

range and the software and hardware versions.

While switch-on the tension meter, make sure not to move it. Otherwise, the
automatic zero adjustment will be faulty.

3.3.3 Switching the tension meter off
Automatic switch-off (if enabled):

- After an idle period of 3 minutes, the tension meter switches off.

Manual switch-off:

- Press and hold the button for 5 seconds.

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 proce­dure will delete all settings, including any customer-defined material characteristics
(calibrations); the factory calibration, however, will be kept.

Customer calibrations will be deleted.

3.5.2 Zero adjustment of the measurement position

Each time the measurement position is changed, the tension meter will automatically
perform a zero adjustment.

If the tension meter does not display zero in its measuring position, perform
a manual zero adjustment procedure.
For this purpose, no material to be measured must have been inserted yet!

Requirements:

- The tension meter has been switched on as described in chapter 3.3.2.

To carry out zero adjustment:

- Bring the tension meter into the desired measuring position and make sure not to move
it.

- Press the button.

The DISPLAY momentarily shows

0 0 0 0

and then switches to

0

Inserting the material to be measured:

- Push the thumbpiece in the direction of the arrow into its threading position 1
(Fig 3.5.3a) until the outer guide rollers extend beyond the filament guide.

- Position the material to be measured into the tension meter in such a way that it
contacts the Filamente guide and passes between the outer rollers and the middle
measuring roller (see fig. 3.5.3a).

- Slowly move the thumbpiece back into the adjustment position (Fig. 3.5.3b).
It is important to ensure that the material to be measured runs smoothly between the
measuring roller and the guide rollers.

- Push the thumbpiece into the measuring position (2) (Fig 3.5.3b).

- The display shows the measured tension value.

If the thumbpiece is not in position 2, a corresponding
message is issued on the display. If the thumbpiece is
not locked, faulty measurements might result.

3.5.3 Inserting and removing material to be measured (cont.)

Press the and button simultaneously to change the different display modes
during the working mode.

Do not let the thumbpiece snap back as this could affect the calibration and
damage the instrument.
While measuring the thumbwheel of the material thickness compensator
must be set to the measurement position, so that the material diameter is not
altered inadvertently.
If you rotate the thumbwheel while the thumbpiece is in position 2
(measuring position), the reading on the display will be updated, but the
value will not be used by the instrument to determine the tension – false
measurement!

To remove the material to be measured:

- Push the thumbpiece in the direction of the arrow into its threading position (1)
(Fig 3.5.3b).

- Remove the material to be measured.

- Slowly set back the thumbpiece into the adjustment position (0) (Fig. 3.5.3b).

22

3.5.4 Damping

Feature to be used for tensions that vary strongly

In the Damping menu (chapter 3.4.1), you can specify separate damping factors for
each material characteristic. Back in the display mode, press the

button to activate or
deactivate the damping function. This is recommended if the displayed values vary stron­gly. Press the button to increase the damping value or the button to decrease it.

Changes made to the damping factor using the arrow keys are not saved perma­nently in the material characteristic. If you disable the damping feature or select
a different material characteristic, the damping factor will be reset to the value
originally saved for the material characteristic.

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

3.5.5 Using the alarm function
Requirements:

In the Material Setup menu, make sure that the MIN and MAX limit values have been set
for each material characteristic.
The limit value alarm can be enabled in the main menu.

3.5.6 Cal. Adjustment

By performing a calibration adjustment, you can adjust a material characteristic
calibrated for a particular material to a different material or diameter without creating
a new material characteristic.

Requirements:

- Prepare the measuring setup as shown in Fig. 3.5.6a.

- Make sure that the thumbpiece is in the adjustment position (chapter 3.5.3).

- Set the material thickness as described in chapter 3.5.1.

- Select the desired material (chapter 3.4.1).

- Move the tension meter into the desired measuring position and carry out a zero
adjustment, if required.

Adjusting:

- Select the „Cal. Adjustment“ menu item from the main menu (Fig. 3.5.6b)

- Insert the material to be measured (chapter 3.5.3) and push the thumbpiece into the
measuring position.

- Press the or key to perform the calibration adjustment until the value on the
display corresponds to the weight suspended to the material.
The adjustment can be performed in 1 % steps within the range from + 10 % to - 10 %.

- Press the button to save the determined value.

Please note that this is a general value. So determine it separately for each mate­rial characteristic and note it down for later reference. It is not possible to save it
per material characteristic.
To disable calibration adjustment, reset the value to 0 % in the „Cal. Adjustment“
menu.

3.5.7 Peak value

During a measurement cycle, the tension meter automatically calculates the Peak Mi­nimum and Peak Maximum values. If these values should not be displayed in the bar
graph or in the statistics, disable their display in the main menu. Regardless, the Peak
values will be used and shown always in the software Tension Inspect 3.

24

3.6 Creating a material characteristic

The tension meter has been calibrated on material 1 and material 2 according our
SCHMIDT procedure for a vertical material path and cannot be deleted or overwritten.
The the materials and diameters are given in chapter 2. Factory calibrations using custo­mer supplied materials follow the same procedure. In this case, however, the calibration
on Schmidt material 1 and 2 is omitted

The material characteristics 1 and 2 have been preset in the factory and cannot be
overwritten. For these material characteristics, you can only change the damping
factor, the alarm function setting, and the limit values.

3.6.1 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 two factory-preset materials, you can
save up to 9 additional materials.

The material thickness unit used for the calibration is the same as currently
selected in the „Settings menu“.
It is not possible to overwrite the factory calibrations.

Calibration Units and Calibration Points

- You can select Newton or Kilogram as the unit of the calibration weights.

- For the calibration of the tension meter, three calibration weights are used. For
example, if you select 10 %, 40 %, 70 % for the calibration, the weights must
correspond to 10 %, 40 %, and 70 % of the measuring range.
In this example, you need the following weights for the DTX-1000:
Calibration in Newton: 100 cN, 400 cN, and 700 cN
Calibration in Kilogram: 100 g, 400 g, and 700 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 Ø 1 Ø 2

Steel wire cN 10 %, 30 %, 50 % 0.4 mm 0.6 mm

25

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: 10 %, 40 %, 70 % 10 %, 30 %, 60 %
10 %, 30 %, 50 % 10 %, 20 %, 40 %
10 %, 40 %, 90 % 10 %, 60 %, 90 %
10 %, 60 %, 100 %

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.

In the „Material“ menu, select Calibration.

To perform the calibration procedure

- Select a new material or edit an existing one (by re-entering the values) from the
„material“ menu.

- Enter a designation (you can use the software supplied with the tension meter
alternatively).

3.6.1 Calibration procedure (cont.)

Requirements:

- The thumbpiece must be in the adjustment position (Fig. 3.5.3b).

- The material thickness compensator (if existing) must be set to the adjustment position
(chapter 3.5.1)

- The unit for the material thickness must have been set (chapter 3.4)

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.

26

3.6.1 Calibration procedure (cont.)

Step 2:
Set the diameter
This step is only required for tension meters with a material thickness
compensator

Step 3:
Perform a zero adjustment with the tension meter in its measuring
position

Step 4:
Calibrate calibration point 1
Insert material to be measured

Step 5:
Calibrate calibration point 2

Step 6:
Calibrate calibration point 3

Step 7:
Exit the calibration process or calibrate a second diameter. In this
case, continue with step 2.

By calibrating a second diameter, you can define a material thickness range to be
used for the material, e.g. 0.1 - 0.3 mm.
Therefor the tension meter can be used for a diameter range instead of a specific
diameter only

Once you have completed the calibration, make sure to verify it as described
in chapter 3.6.2. In case of a large deviation, repeat the calibration or select
different calibration points.

3.6.2 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 and material 2 according our
SCHMIDT procedure for a vertical material path and cannot be deleted or overwritten.
The diameters and materials are 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 thumbpiece 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 material to be measured 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 3.5.3.

3.7 Memory functions

The tension meter is delivered with 4 different memory modes. You can store up to 255
measurement series at one or more machine positions. The tension meter can store up to
60000 measured values.
All saved measured values and statistic datas can be transferred to a PC (for further pro­cessing, e.g. in Excel). For this purpose, use the software supplied with the tension meter.
Recall of memory: The display only shows the last measured value, the average, the
minimum and maximum measured values, the peaks, the standard deviation and the
number of measured values per measurement series.
By pressing the button you can transfer all data from the selected measurement
series to a PC.
You can select the desired memory programs from the main menu.

Memory Mode “S” – Standard

6 Cleaning

For cleaning the unit do not use any

AGGRESSIVE SOLVENTS

such as trichloroethylene or similar chemicals.

NO WARRANTY OR LIABILITY

shall be accepted for damage resulting from improper cleaning.

The question of finding the right frequency of 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
user‘s Quality Assurance Department, based on the user‘s experience.
Assuming normal operating time and load as well as careful handling of the tension meter,
we recommend a verification interval of one year.

7 Verification interval

5 Service and maintenance

You should regularly inspect the rollers to assure that they are running easily and smooth­ly. You can replace the rollers yourself, as necessary. Please indicate the tension meter

5.1 Rollers

The tension meter is easy to maintain.
Depending on operating time and load, the instrument should be checked according to the
locally valid regulations and conditions (as described in Chapter 3.6.2). The use of other
test methods than the procedure described in Chapter 3.6.2 may cause deviating measu­ring results.
