5.1 Cleaning
Injuries are possible!
An incorrect application of the SONOCHEK and its accessories
may pose a hazard to the user.
Do not open the SONOCHEK and the sensors. They do not contain any
device parts to be cleaned, maintained or repaired by the user.
Device damage is possible!
An incorrect use of the SONOCHEK and its accessories may lead
to damage and, in the worst case, to the destruction of the device
technology.
The SONOCHEK and the sensor system are not waterproof. Do not
submerse the device technology in liquids.
Also protect the SONOCHEK and the associated sensor system from
penetrating moisture, as otherwise device damage cannot be ruled out.
Do not use any strongly corrosive or scratching cleaning agents.
Use damp cloths to clean the device and all accessories. Aggressive cleaning agents may
abrade the plastic housing of the SONOCHEK and impair the mechanical stability.
Clean the sensors regularly from the outside with a damp cloth and a mild, non-abrasive
cleaning agent.
5.2 Checking the measuring accuracy
The DBS10 and DBS20 sensors are calibrated upon delivery. The calibration certificates are
enclosed with the case. To ensure high measurement accuracy of the sensors, you should have
them checked every two years from the date of issue of the calibration certificate. Send the
sensors to your PRUFTECHNIK representative for inspection.
If you notice an irregular measuring behavior of a sensor, you should no longer carry out any
measurements with the sensor and send the sensor to PRUFTECHNIK for servicing.
