2. Safety
DANGER!
Danger of death caused by electric current
Operation using a defective power supply unit (e.g. short circuit from the
mains voltage to the output voltage) can result in life-threatening voltages
at the instrument!
Special conditions for safe use
WARNING!
If the CPG1000 has been exposed to overload or sudden physical shock
(e.g. being dropped) it should be checked for signs of damage that may
cause concerns about safety. If there is any doubt, return the unit to WIKA
for evaluation. For information on returning the instrument see chapter
9.2 "Return".
The CPG1000 is not intended for use with ammable substances and must
be used only in locations which provide sucient protection against the
intrusion of solid foreign objects or water which could impair the safety.
CAUTION!
To avoid possible damage to the calibration reference or to equipment
under test:
■
If the message "OL" is displayed, the measuring range has been
exceeded and the pressure source must be removed immediately from
the CPG1000 in order to prevent damage to the internal sensor.
■
The maximum permitted torque of the thread is 13.5 Nm = 10 ftlbs. This
permitted torque must NEVER be exceeded.
■
When screwing the NPT thread of the CPG1000 to an adapter or
a process connection, it is necessary to use an additional sealing
compound, e.g. Teon tape between the threads.
■
The sealing has to be made with Teon tape directly via the NPT thread
and not via the manifold at the CPG1000.
