1.0 INTRODUCTION 1.1 Operation and handling Switching on: Press the button for 3 seconds. Changing the calibration curve: or key. Switching on the display lighting: Press the button briefly; the lighting switches off automatically after approx. 20 seconds. Pressing any key activates the lighting again and prolongs the switch-off time to 4 minutes. Switching off: Press the key for 5 seconds; the device will switch off after releasing the key. After approx. 4 minutes the device will switch off automatically. 1.2 Measuring procedure 1. Switch on the humimeter LM6 by pressing the key for 3 seconds. 2. Select the appropriate calibration curve using the arrow keys. Hold the device in one hand and press it onto the leather well-setted (4 kg compacting pressure). The leather pile has to be at least 10mm high! 3. The display shows the water content immediately (large numbers). 2
2.0 CALIBRATION CURVES NAME CALIBRATION CURVE DENSITY Leather LD Leather of low density 0.55 g/cm³ Leather CR Leather chrome tanned 0.60 g/cm³ Leather MD Leather of medium density 0.65 G/CM³ Leather FOC Leather free of chrome, fire protection leather 0.70 g/cm³ Leather HD Leather of high density 0.75 g/cm³ Leather VHD Leather of very high density 0.80 g/cm³ Reference Only for checking the instrument 2.1 Selection of calibration curves Due to different manufacturing methods and different densities of the leather there is no standardised allocation of calibration curves. In the above list of calibration curves you can find information regarding manufacturing methods and density that enables a preselection of the calibration curve. To ensure the best accuracy of your measurement, we recommend to carry out a comparison measurement by kiln-drying (norm DIN 53304) once: 1. Take a leather pile of 10-15mm of the format A6 with average moisture content. 2. Measure the water content of this leather pile using all available calibration curves and write down the measuring results of the different calibration curves. 3. Take the 2 top leather pieces of the pile and carry out a reference measurement according to DIN 53304. 4. Compare the determined reference water content with the measuring results of the different calibration curves. Use the calibration curve with the measuring result nearest to the reference water content. 3
3.0 DETERMINATION OF THE REFERENCE WATER CONTENT The humimeter LM6 determines the water content, which means that it calculates the moisture referred to the total mass (DIN53304): Mn Mt % WG = 100 Mn Mn: Mass with average moisture content Mt: Mass of the dried sample %WG: Calculated water content 3.1 Short description of norm DIN53304 Take a leather piece according to DIN 53302 T2 or DIN 53303 T2. For the determination of the water content, weigh the leather piece with an accuracy of 0,001 g (mass Mn). Put the piece of leather in a glass bowl that was dried at (102 ± 2) C and was weighed after cooling to room temperature. Dry the opened glass bowl in a drying chamber at (102 ±2) C for 5 hours. After closing the glass bowl cool it in an exsiccator. Now determine the mass (Mt). After that, go on with the above described drying procedure in the drying chamber for one further hour, cool and weigh again. If the weight after the second drying period decreases less than 0.1 % of the initial weight, the assay is finished. If the decrease of weight is higher than 0.1 %, the drying has to be continued. The total period of drying must not exceed 8 hours. 4

5.0 COMMON REASONS FOR INCORRECT MEASUREMENTS Wrong calibration curve Double check the correct selection of the calibration curve before measuring. The calibration curve reference must NOT be used. Inadequate thickness of the leather pile A single leather hide must NOT be measured. Pile the leather to ensure a thickness of at least 10 mm. Metal below the material During the measurement there must NOT be any metal for at least 100 mm under the measured material. Product temperature out of application range The application range is between 0 C and +40 C Discrepancy in temperature between device and material Please ensure that the device and the material under test are being stored at nearly the same temperature before measuring. A high temperature difference has a negative effect on the stability of the measurement results. 6.0 LOOKING AFTER THE INSTRUMENT Do not drop the instrument or expose it to excessive temperatures. Only clean it with a lint-free, dry cloth. The instrument is not waterproof. How often you need to check the instrument depends on the use and the required level of accuracy in your field of operation. For a fee, Messtechnik Schaller GmbH can also carry out a calibration at their factory. In this case you will also receive a calibration certificate. 6.1 Exemption from liability For miss-readings and wrong measurements and of this resulting damages we refuse any liability. As this rapid measurement procedure is influenced by product-specific and application-specific conditions, we recommend to carry out a plausibility check on the measurement results. Each instrument has a serial number and a warranty seal. If this is broken we cannot provide warranty. If the instrument is defective, contact Messtechnik Schaller GmbH or your supplier. 7
7.0 CHANGING THE BATTERIES Your new device is provided with batteries. Please find enclosed the manual for changing of batteries: 1. At first remove the rubber protective housing. For that, hold the rubber housing at the upper side and pull it over. If your humimeter is provided with an optional USB port, you have to remove the protection cap before. Press with your finger onto the arrow of the battery cap und pull it back. 2. Remove the empty batteries. 3. Put four new batteries in the device. Make sure that the position of the battery poles is correct. 4. Press down the batteries and close the cap. 8
8.0 CALIBRATION 8.1 Checking the calibration We recommend to check the calibration of the humimeter LM6 every 4 weeks, using the proof plate delivered with the device. For this check the device has to show a temperature between 18.0 and 24.0 C. 1. Switch on the instrument and select the calibration curve reference using the arrow keys. 2. Hold the humimeter LM6 in one hand and press it onto the grey proof plate (compacting pressure of 4.0kg). The shown measuring value should range between 14.5 and 15.5. 3. If the shown value is out of this range, you have to carry out a calibration (see instructions below) 8.2 Calibration procedure By a zero point adjustment you can correct a too high deviation of the calibration check. For that please proceed as follows: 1. Press the left key twice to reach the menu level. Navigate to the menu item Options using the arrow keys. Confirm by pressing the button. 2. Select the menu item Calibrate using the arrow keys a znd confirm by pressing the button. 3. This menu item has to be unlocked. For that you have to enter the 4-digit serial number of your humimeter LM6. You can find the serial number on the top right edge of your display a short time after switching on the instrument, or on the sticker in the battery slot. 9
4. Press the third button as long as the black bar stands on the first digit of the serial number. After a waiting time of a few seconds the device accepts the entered digit. Now the other 3 digits have to be entered. When the 4-digit number has been entered correctly (see picture), press the button to confirm. 5. The request Reinitialize? will appear at the display. Hold the humimeter LM6 in one hand and make sure that nothing stands behind the measuring field (black plate). 6. Now press the second button ( ) with one finger. The calibration procedure will take a few seconds. During that time, the instrument has to be held up in the air and the measuring field must NOT be touched. 7. The device is ready when the shown picture on the right disappears automatically. 10
