2.3 Special hazards
WARNING!
■ If it is obvious that safe operation of the instrument is no longer possible, the
instrument must be put out of operation and marked in order to secure it against
inadvertent use.
■ The measurement signal of the reference (or test sample) can be influenced by
massive electromagnetic irradiation and/or the indication of the signal could be
completely absent.
■ If the Hand-Held pressure indicator CPH6300 is used in applications with oil as
a pressure medium, make sure it will not be used with flammable material or
gases directly afterwards since it can lead to dangerous explosions and danger
to personnel and machinery.
■ Pressure sensor CPT6200 should only be fitted or removed when the system is
free from pressure.
■ Observe the working conditions in accordance with chapter “3. Specifications”.
■ Always operate the pressure indicator within its overload limits.
■ This device must not be used at potentially explosive areas! The usage of this
device at potentially explosive areas increases danger of deflagration, explosion
or fire due to sparking.
■ When connecting the device to other devices the connection has to be designed
most thoroughly as internal connections in third-party devices (e.g. connection
GND with protective earth) may lead to undesired voltage potentials that can
lead to malfunctions or destroying of the CPH6300 and the connected devices.
