Use the same basic keypad operations described in
previous setup procedures to enter the desired value
for the displayed relay activation setting.
5.
Repeat this procedure for each relay activation setting.
The analyzer has a passcode feature to restrict access to
configuration and calibration settings to only authorized
personnel.
•
DISABLED:
With passcode disabled, all configuration
settings can be displayed and changed, and the analyzer
can be calibrated.
•
ENABLED:
With passcode enabled, all configuration set-
tings can be displayed -- but they cannot be changed, and
the analyzer cannot be calibrated. When you attempt to
change a setting by pressing the
ENTER key
, a displayed
notification requests 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 and return 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.
