Password protection can be used to limit the use of this command. New
parameter values are saved in non-volatile memory (EEPROM)
System parameters saved in the EEPROM are:
- Automatic message number
- Visibility alarm limits
- Offset reference
- Signal scale
- Password characters
- Unit id characters (2)
- References and limits for contamination monitoring
- Baud rate
- Serial number
- EEPROM checksum
- Relay control mode and Relay delays
- Analog output mode and range
- Hood heater usage
To prevent unauthorized change of the system parameters, a four-
character password can be set. If no password is set, the command
continues as if it had the correct password.
When no password has been set, the command is the following:
CONF
When a password has been set in a previous session, the command
format (max. four character string, printable characters) is the following:
CONF password
If the previous password is known, the password can be changed with the
CONF password N command, where the N character stands for new.
After getting the correct password, the system asks for a new password.
Press ENTER to remove the password. Otherwise, type a new password.
The system response to the CONF command is presented on the next
page.
