4 Getting started
4.1 Power supply
When the battery level is too low, the battery icon will appear in the display. To change the batteries, open the battery compartment cover and replace the used batteries by new ones. Make sure the polarity is correct.
4.2 Material selection
Press the On / off key to switch on the device. Then press the material selection key. The display will now show a material code “cdxx” or ,,yyyy”. ,,cd” is the abbreviation for code and ,,xx” indicates the material number 1…11. The material numbers assigned to each material can be found in the chart below. If you wish to enter the sound velocity individually, you can select ,,yyyy”. The sound velocity must be entered in advance by pressing the sound velocity key.
|10||cd10||Grey cast iron|
Press the Plus or Minus key to select a material code and confirm the code with the material selection key. The display now shows 0. If you select a code without confirming, the display will also show 0 after a few seconds and the material is considered as confirmed.
Attention! It is essential to select the material before making a measurement as otherwise the measured values will be incorrect.
Press the On / off key to switch on the device and select the unit by pressing the Unit key.
Make sure the sensor is correctly connected to the device. If this is the case, will appear in the display.
Apply some coupling gel to the surface and press the sensor onto the material you want to measure. The reading will now be displayed until another measurement is made or until the meter is powered off.
5.2 Measurement with set sound velocity
Press the sound velocity key. The device immediately switches from the material selection to sound velocity mode. The sound velocity last set will be displayed. You can use the Plus and Minus keys to change the sound velocity value. At each keypress, the value is increased or decreased by 10 m/s. If any of the two keys is pressed and held for more than 4 seconds, the value will be changed by 100 m/s. Apply some coupling gel to the surface to be measured and press the sensor onto the surface. The reading will be shown on the display. If you do not know the material to be measured, do the following: Measure the thickness of the material at one point (e. g. with a caliper) and make a note of the thickness. Now measure with the meter and change the sound velocity until the displayed value is the same value as the one you wrote down. Write down the sound velocity set for the material. If you would like to make further measurements of the current material, you must set the determined sound velocity before you start a measurement.
Apply some coupling gel to the 5 mm standard block and press the calibration key. CAL will be displayed.
Press the sensor onto the standard block. If the sensor is correctly connected, will be shown in the display. After that, 5 mm and CAL will be indicated. When the displayed value is stable, press the Calibration key again to apply the value and to get back to measurement mode. The calibration is now completed and the value is saved to the meter.

For the disposal of batteries in the EU, the 2006/66/EC directive of the European Parliament applies. Due to the contained pollutants, batteries must not be disposed of as household waste. They must be given to collection points designed for that purpose.
In order to comply with the EU directive 2012/19/EU we take our devices back. We either re-use them or give them to a recycling company which disposes of the devices in line with law.
For countries outside the EU, batteries and devices should be disposed of in accordance with your local waste regulations.
