6.1 Requirements for test assemblies with the CPH6000
GB
Initially the test assembly must be physically assembled and, if necessary, connected
electrically (see chapter 4.4.1 "Connection of the model CPT6000 reference pressure
sensor").
Before switching the CPH6000 on, ensure that the test assembly is not pressurised
(system is vented to atmosphere) and that the equipment is correctly assembled and in
the correct mounting position.
Particularly small measuring ranges (e.g. < 1 bar) are orientation dependent (i.e.
the mounting position considerably influences the measurement signal). This can
be compensated, if necessary, using the TARE function (see chapter 7.4.1 "SETUP
additional menu item: Functions").
Absolute-pressure measuring ranges < 1 bar absolute are, by definition, in an overload
condition at atmospheric pressure. Therefore the message "Sensor Overflow"
appears in the display, indicating a pressure outside of the measuring range of the
attached sensor. If the pressure is reduced, so that it falls within the permissible
measuring range, then this message disappears from the display. Since absolute
pressure measuring ranges < 1 bar are always ‚overloaded' at atmospheric pressure,
for these measuring ranges the overload time limit function is deactivated in the SETUP
menu option: ReferenceSensor (see chapter 7.4.3 "SETUP additional menu items:
ReferenceSensor").

Before starting any task, the device should be switched on briefly to
determine that there is sufficient charge in the battery. (battery level
in %). The battery level is indicated briefly after powering up in a device-
status message (see chapter 7.2.1 "Device-status message shortly
after switching on the CPH6000"). 100 % battery charge will enable
approximately 20 hours of instrument operation.
Only disconnect test and calibration installations once the system has
been depressurised!
