new ones. Make sure the polarity is correct.

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.
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.
