WARNING!
Observe the information given in the applicable type examination
certificate and the relevant country-specific regulations for installation
and use in hazardous areas (e.g. IEC 60079-14, NEC, CEC).
Non-observance can result in serious injury and/or damage to

WARNING!
■
Pressure sensors should only be mounted or dismounted when the
system is free from pressure.
■
Observe the working conditions in accordance with chapter
3 "Specifications".
■
Always operate the pressure calibrator within its overload limits. See
chapter 3 "Specifications".
■
Do not apply a voltage greater than the specified voltage to the
instrument. See chapter 3 "Specifications".
■
Residual media on the dismounted calibrator and/or sensors can
result in a risk to persons, the environment and the equipment. Take
sufficient precautionary measures.
■
Only use those accessories available from WIKA for the calibrator.
■
Make sure that the test probes never contact a voltage source while
the test cables are connected to the current terminals.
■
The measurement signal of the reference (or test sample) can be
influenced by large electromagnetic effects and the display of the
signal may be lost completely.
