5 Using the product CAUTION Hot probe shaft! Risk of burns! > Allow the probe shaft to cool down after a measurement, before touching it! > Only attach the silicone hose to the probe shaft once it has cooled down! 6.
Mild household cleaning agents and soap suds may be used. Any cleaning of contamination within the probe shaft may only be carried out by Testo Customer Service. 6.3. Draining the condensate container The fill level of the condensate trap can be monitored via the markings on the condensate trap.
6 Maintaining the product 2. Open the sealing plug of the condensate trap. 3. Let the condensate run out into a sink. 4. Dab off any remaining drops on the condensate outlet with a cloth. 5. Close condensate outlet with sealing plug and press on it firmly. The condensate outlet must be completely closed, other- wise measuring errors could occur if external air gets in.
