Page 18: Error Messages
The fi lter (or diffusion) stage current reached its maximal value (overrange) At very high particle concentrations (larger than one million particles per cm3), the testo DiSCmini electro- meter amplifi ers might reach their maximal level. In this case, all calculated signals (number, diameter, LDSA) are no longer correct. -
