Cautions For Testo Discmin - TESTO DiSCmini Instruction Manual

Caution for Testo DiSCmini
Impactor tubes
Silicone or electrically conductive-based tubes lead to rapid contamination of the coro-
na wire. Use only the supplied tubing for measurement. Suitable tubes are available at
Testo SE & Co. KGaA or your local distributor.
Condensing conditions
Never operate the instrument at condensing conditions; e.g. do not measure exhaust
gas directly. Condensing water may damage the instrument.
High particle concentrations
To avoid premature aging of the instrument, do not expose it to extremely high aerosol
concentrations such as undiluted cigarette smoke.
Large particle
testo DiSCmini measures nanoparticles. If you use it to measure microparticles (>~0.7
μm) you will get wrong readings. Before starting any measurement, the impactor must
always be fi tted, either directly to the instrument or to the end of the sampling extension
set..
SD-card interface
SD-card interface is made and tested for use of SD-cards from Testo. Only use the SD-
card delivered with the instrument.
