1 SAEFTY PRECAUTIONS
• Carefully read these operating instructions completely
before operating this instrument. This is necessary to
avoid damage to it, as well as for user-safety.
• Only use the instrument for the purpose for which it was
designed.
• Only use the instrument in dry rooms in which there is no
risk of explosion.
• Protect Cobra4 Sensor-Unit Conductivity+ from dust,
moisture and vapours. Use a slightly moist lint-free cloth
to clean the instrument. Do not use aggressive cleaning
agents or solvents.
• Take care that no liquid penetrates in through the hous-
ing openings, as such penetration would result in dam-
age to Cobra4 Sensor-Unit Conductivity+.
• Only use the experimental set-up for the purpose for
which it is intended.
• Do not open up the instrument.
• Only connect the data output of Cobra4 Sensor-Unit
Conductivity+ to the measured data recording instru-
ments specifically intended for it.
• The present-day state of software development makes it
impossible to guarantee that a product is free of faults.
PHYWE Systeme GmbH & Co. KG therefore does not
take on any liability for damages that occur during the
installation or the use of the instrument.
