6. Commissioning, operation
Function lock
Access to adjustable parameters can be partially deactivated, once they are set, to prevent
unauthorised changes to the configuration. This is accomplished through a password-
protected “supervisor mode”. Press the Enter key to access the Supervisor Mode or the
CONFIG key to return to normal operation.
6.3 Supervisor mode (Control mode)
As soon as the "FUnC LOCK" message is displayed, press the Enter key. The 0PWRD
message appears on the display. The password for the Supervisor Mode is 101. It is
entered using the ▲ and ▼ keys. If a key is held pressed, the display scrolls more quickly
and the settings can be entered faster. The password is factory set and cannot be changed.
1. The CPG1000 is factory set in such a way that access to all settings is enabled and all
settings can be changed.
2. In the Supervisor Mode, any parameter can be locked or unlocked using the ▲ and ▼
keys. Parameters that should not be freely accessible are locked using the LOG option
and unlocked using the UnLOC option.
3. The functions that can be locked or unlocked are:
■ Zero function (enable/disable)
■ Set pressure units (enable/disable)
■ Setting of the automatic power off (enable/disable)
■ Damping settings (enable/disable)
■ Setting of the sampling rate (enable/disable)
■ Tare setting (enable/disable)
■ User-defined engineering units (set scale factor)
4. Using the CONFIG key search for the options mentioned above and lock and unlock
functions using the ▲ and ▼ keys. To scroll through the parameters press the CONFIG
key, and press the Enter key to save the settings and switch the CPG1000 back to
normal operation. If a function is locked, it can neither be accessed nor can you change
the current status. To modify a locked function, enter the Supervisor Mode and unlock
the function. Once it has been modified, if necessary, enter the Supervisor Mode to lock
it again.
5. Setting of a user-defined unit or scale: The last menu option in the Supervisor Mode is
SET FACTOR. Using this option you can define a multiplier between 0.001 and 100 for
a user-defined unit. The defined factor is multiplied by the psi measured. The result is
displayed. Example: 40 psi corresponds to 1,000 g of a product in a tank. The weight
of the product should appear on the display, a pressure gauge for 100 psi is used. If 25
is defined as the multiplier, the pressure of 40 psi corresponds to the value 1.000 (40 x
25). "CUST" is displayed on the instrument as the engineering unit.
