12. MAINTENANCE AND CLEANING
The product requires no servicing apart from replacing the rechargeable battery and cleaning
of the measuring probes. Do not disassemble the product (except for the work described in
these operating instructions, such as for exchanging the measuring probes).
Clean the product with care, e.g. with a soft, clean cloth. Do not push on the display too much;
this will not only cause scratches but may also damage the display.
Only use distilled water (or deionised water) to clean the tips of the measuring probes, since
the measured values may otherwise be influenced. Use only paper tissues to dab dry/dry the
measuring probes.
Do not use any aggressive cleaning agents for cleaning, do not use any alcohol or even
chemicals; this may cause not only discolouration but also damage to the product.
