WARNING!
Physical injuries and damage to property and the environment caused by hazardous media
Upon contact with hazardous media (e.g. oxygen, acetylene, flammable or toxic substances), harmful media
(e.g. corrosive, toxic, carcinogenic, radioactive), and also with refrigeration plants and compressors, there is a
danger of physical injuries and damage to property and the environment.
Should a failure occur, aggressive media with extremely high temperature and under high pressure or vacuum
may be present at the instrument.
▶
For these media, in addition to all standard regulations, the appropriate existing codes or regulations must
also be followed.
▶ Wear the requisite protective equipment.
DANGER!
Danger to life caused by electric current
Upon contact with live parts, there is a direct danger to life.
▶
The instrument may only be installed and mounted by skilled personnel.
▶ 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!

Switching the pressure calibrator on or off

6.1.1 Switching on the pressure calibrator

By pressing any button, the pressure calibrator will be switched on. The calibrator requires a warm-up for a few minutes
(max. 5 minutes) to reach its specified accuracy. Large changes in ambient temperature may make a longer warm-up period
necessary. The pressure display of the calibrator should be zeroed before starting the pressure calibration.
Directly after the CPH6000 is switched on, the following status message is displayed briefly with the current settings:
Voltage 24V
1
The voltage supply of DC 24 V (available at the upper end of instrument) can,
during the configuration of each operating mode, be switched on or off. If it
is not needed for a measurement, then it should be switched off, in order to
conserve energy.

Height difference
3
In the "SETUP\CPH configuration" menu, set the height difference between the
test item and the CPT6000 reference pressure sensor. This value influences an
automatic correction calculation in order to eliminate any pressure difference
based on a medium column. This value must be correct for the following
measurement process and/or be adjusted accordingly in the "SETUP/CPH
configuration" menu.
→ See chapter 6.9.5 "CPH configuration".
Temperature
4
In the "SETUP\CPH configuration" menu, the temperature (ambient temperature) is entered. This value can be adjusted
accordingly in the "SETUP\CPH configuration" menu.
→ See chapter 6.9.5 "CPH configuration".
