Only connect to test- and calibration installations in the depressurised
condition (atmospheric).
Push the power button briefly to turn the instrument on. Push the button again to turn it off.
After switching on the firmware version is indicated on the display for approx. 1 second.
6.1 Normal operation
Turning on and off the background illumination: Press the Enter key.
Zeroing the display: Press and hold the ZERO key.
For absolute pressure gauge after pressing the ZERO key, the baromet-
ric reference value has to be entered. Use keys ▲ and ▼ to set the value.
Confirm with ENTER.
As the calibration was realised with this value, it is recommended not to
change the reference value set ex-works.
MAX/MIN: The CPG1000 stores the minimum and maximum pressure in the memory. If
the MAX/MIN key is pressed once, the maximum pressure from the memory is displayed.
If the MAX/MIN key is pressed again, the minimum pressure from the memory is displayed.
After 2 seconds the instrument returns to normal operation. To delete the memory registers
holding the values for MAX/MIN, hold the MAX/MIN key pressed for at least 2 seconds until
the “CLr” message is displayed. The bargraph on the lower edge of the display indicates
the present pressure proportional to the entire measuring range.
If a TARA value has been programmed for the CPG1000, the displayed pressure does not
correspond to the actual pressure applied.
6.2 Setup and configuration
Press the CONFIG key to access the functions of the instrument which are adjustable by
the user. Every time the CONFIG key is pressed, the display switches to the next function.
As soon as a function is configured, press the Enter key to close the Configuration menu,
or the CONFIG key to continue configuration.
