prompts in the column starting with [out] will be displayed. Use the Up or Down arrow keys to display
the prompt above or below. If the prompt at the top or the bottom is displayed, the program will loop
around. Press the Up or Down key until [AL] is displayed. Press the Left key to return to the sample
display. Press the Right key again and [AL] will be displayed.

Standby Mode
In standby, the alarms will not function and the 4 mA to 20 mA outputs will go to 4.00 mA. When
SAMPLE is pressed, the inputs will show [StbY].
The analyzer will not resume normal operations until the analyzer is taken out of standby. While in
standby, the entire menu and all of the settings are accessible to the operator as before. None of the
settings will take effect until the analyzer is returned to normal operation.
The standby feature is protected by security level 2.
