Page 4: Warranty And Liability
Warranty: - SCHMIDT tension meters are warranted for 12 months. Parts subject to wear, electronic components and measuring springs are not covered by the warranty. No warranty or liability will be accepted for bodily injury or property damage resulting from one or several of the following causes: - Misuse or abuse of the device. -
Page 5: Informal Safety Measures
The device is intended exclusively to be used as a tension meter. Any other use or any use exceeding this intention will be regarded as misuse. Under no circumstances shall HANS SCHMIDT & Co GmbH be held liable for damage resulting from misuse. The intended use also includes: - Complying with all notices included in the Operating Instructions and observing all inspection and maintenance works. -
Page 6: Available Models
PA: 0.50 mm Ø * 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. For this purpose a material sample of about 5 m should be supplied. -
Page 7: Connecting The Tension Meter
The ID plate with the CE mark and the serial number as well as the calibration label (optional) and the SCHMIDT Quality Seal are provided at the rear side of the instrument. -

3.3.2 Battery change (Cont.) Battery 3.3.3 Switching the tension meter on Press and hold the button (for approx. 1 sec.) until the DISPLAY shows the mea- suring range, the software and hardware versions, e.g. E 1.0, and then “0”. During startup, the tension meter performs an automatic zero adjustment. If the tension meter does not display zero, perform a manual zero adjustment procedure (see chapter 3.5.1). - Page 12 3.4 Tension meter settings Cont.

- Insert a password and choose a protection level - Exit the main menu, to apply the password protection The factory setted password is „0000“ If you forgot the password, please contact HANS SCHMIDT & Co GmbH to request the master password. -
Page 14: Factory Reset
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. Operating Procedure Requirements: - Tension meter switched on as described in Chapter 3.3.3. -
Page 15: Measuring The Upper Tension
3.5.2 Measuring the Upper Tension To insert the process material: - At the sewing machine, thread the upper thread all the way through to the take-up lever - Thread the upper thread through the first ceramic eye, - and then through the measuring rollers (see material path symbol on front side) It is important to assure that the upper Thread runs smoothly between the measuring rollers. -
Page 16: Measuring The Lower Tension
3.3.3 Measuring the Lower Tension Requirements: - Fixture to determine bobbin case removed from postition 1 and screwed in at postition 2. - Tension meter switched on as described in Chapter 3.3.3. - Define the required tension meter settings (chapter 3.4) - Select the desired material characteristic (chapter 3.4.1) - Bring the tension meter into the desired measuring position and carry out a zero adjustment as described in chapter 3.5.1, if required. -
Page 17: Damping
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 de- activate the damping function. This is recommended if the displayed values vary strong- ly. -
Page 18: Cal. Adjustment
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. - Select the desired material characteristic (chapter 3.4.1). -
Page 19: Creating A Material Characteristic
The material and diam- eter 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. -

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. - Page 21 3.6.2 Calibration procedure In the „Material“ menu, select Calibration. Step 1: Set the calibration points and weights, e.g. in Newton using the calibration points 10 %, 40 %, and 70 % of full scale Start: Select the Start menu item. Alternative calibration points: 5 %, 45 %, 90 % 10 %, 50 %, 90 % 5 %, 50 %, 90 %...

Page 22: Verifying The Calibration
The diameter and mate- rial 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. -
Page 23: Memory Functions
3.7 Memory functions The tension meter is delivered with 5 different memory modes. You can store up to 999 measurement series at one or more machine positions. The number of storable measure- ment series is depending from the adjusted memory mode and the selected storage time and will be displayed in the setting menu of the memory mode. -
