4.6 SET PASSCODE
(feature enabled or
disabled)
The analyzer has a passcode feature to restrict access to
configuration and calibration settings to only authorized
personnel.
•
DISABLED:
With passcode feature disabled, all configu-
ration settings can be displayed and changed, and the
analyzer can be calibrated.
•
ENABLED:
With passcode feature enabled, all configu-
ration settings can be displayed -- but they cannot be
changed, and the CALIBRATE and TEST/MAINT menus
cannot be accessed without the passcode. When you at-
tempt to change a setting in the CONFIGURE menu by
pressing the
ENTER key
, a displayed notification re-
quests passcode entry. A valid passcode entry saves the
changed setting and returns the display to the “MAIN
MENU” branch selection screen. An incorrect passcode
entry causes the display to momentarily show an error
notification before returning to the “MAIN MENU” branch
selection screen. There is no limit on attempts to enter a
valid passcode.
The passcode is factory-set to “
3456
.” It cannot be changed.
