1 Warranty and liability
In principle, the supply of the device is subject to our “General Conditions of Sale and
Delivery.” These have been provided to the operating company on conclusion of the
contract, at the latest.
Warranty:
- SCHMIDT tension meters are warranted for 12 months.

2 Available models
These Operating Instructions refer to the DTX model of the DT Series; they are
also applicable to the following models:
DTXB, DTXE, DTXF und DTXL.
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.
*** The DTXB, DTXE, DTXF and DTXL models do not include a material thickness
compensator. They are calibrated only on material 1
The DTXB is calibrated depending to the range on a textile ribbon or thin tape.

The Y-axis can be scaled with the and buttons.
3 Scalings: total measuring range, set limits range plus 1/3, set limits range. The
scaling is only possible, if limit values are entered and the damping is not
activated.
With the or button the X-axis can be scaled. The setting range is 0.5 to
50 sec.
The scaling can also be changed during the measurement, whereby values alrea-
dy displayed are deleted when the X-axis is changed.

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 exten-
ded 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.

In the material menu you can make the settings for the selected material characteristics and
perform the calibration. To perform the calibration, the weights for the selected calibration
points must be available.

By setting a password, you can block the access to some menu parts for unauthorized

To apply a changed password, exit the main menu.
Entering 0000 as the password disables the password feature.
If you forgot the password, please contact HANS SCHMIDT & Co GmbH to request
the master password. As an alternative, you can perform a factory reset. Please
note, that in this case, you will lose any customer-defined calibrations.

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.

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
cN
.
The tension meter is now adjusted to its new measuring position and ready to take
measurements.

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.
