Disabling Password Protection
After password protection has been enabled as described in the Installation
chapter, the password protection can be disabled by selecting blanks for the
password. To disable password protection:
1. Enter the current password.
2. When the ENTER NEW PASSWORD screen displays, leave the
password field blank (don't enter any characters) and press ENTER.
The password protection is now disabled and the user will not be prompted to
enter a password when changing consumables or recalibrating the analyzer.
To re-enable password protection, follow the same procedure for setting up a
new password (refer to the Installation chapter).
Service Menu
The SERVICE menu provides a way to test the subsystems of the analyzer for
proper operation. The subsystems that can be tested are the analog board, the
4-20mA outputs, the digital inputs, the RS-232 communication port, and the
printer and the alarm outputs. Contact Ionics Technical Support for instructions
about how to use these diagnostic tests and interpret the results. In addition to
the diagnostic tests provided, you can manually perform an autozero operation
from the SERVICE menu.
