The following graphic shows the location of the internal reference sensors
10.4.1 CPC8000-HM Transducer Removal / Replacement
The front panel can be removed by losing 8 screws to get access to the internal reference sensors.
Before opening the front panel, the system has to be turned off.
CAUTION!
Before removing the transducers, correctly disconnect the instrument from the pressure
supply, switch it off and disconnect it from the mains.
CAUTION!
Further access to the interior of the instrument is NOT allowed. There are no user-
serviceable plumbing or parts inside. In addition to the dangerous voltages present (line
voltage), there are circuits sensitive to electrostatic discharge damage. There are also
several solenoid valves which will run hot enough to cause painful burns under certain
operating conditions. These dangerous conditions will be avoided by limiting interior
access to the areas that are exposed by opening the front panel.
