6.4.1.8
Operating Mode Selection
The operating modes are permanently displayed on bottom of the Home App. The CPC7000 has three operating modes: Measure,
Control and Vent. After the system has switched on, the instrument will automatically be placed in Vent mode. The user can switch
from one mode to the other by using the mode selection keys.
When switching from Control mode to Measure mode, the system will not be vented and the last applied pressure
will be locked in the system by means of a solenoid valve
■
Measure Mode:
In Measure mode the CPC7000 acts like a precision pressure measuring instrument and measures the
pressure applied at the Measure/Control port. If the Control mode was the last used mode before switching into Measure mode,
the last controlled pressure is held in the test assembly.
■
Control Mode:
In Control mode the CPC7000 provides a controlled pressure at the Measure/Control port equal to the setpoint
value. It is activated by pressing the Control button. In order to ensure smooth operation in the control mode, following measures
must be taken and respective parameters must be set.
The control stability and the control rate can be set in the Control Settings App [
]
Control limits can be set in the Control Settings App [
]
■
Vent Mode:
The Vent function will vent the system to the atmosphere, including the test assembly connected to the Measure/
Control port. The Vent mode can be activated from the Measure or Control mode by pressing the Vent button. The rate at which
the pressure is released in vent mode is set in the Control Settings App [
]
WARNING!
Venting will cause a loss of pressure at the vent rate in the system and the plumbing connected to the Measure/
Control port. Care must be taken that the device under test is not damaged during venting.
6.4.2 Settings Application
The Settings App is used to set up general settings for the display. Settings parameters include Language,
Brightness, Volume, User 1 base units, User 1 multiplier, User 2 base units, User 2 multiplier, Barometer units, and
Configuration. Figure 6.4.2 Settings application shows these parameters as indicated when the Settings App has
been chosen. As each parameter is pressed, an input screen will appear on the right where selections can be made.
The Settings App provides a place to change the language, display brightness, volume, user units, and barometer units.
Configuration settings of the unit can also be saved within this application plus the default configuration can be activated.
