Status Indicators
Instrument Status Indicator
The instrument status indicator indicates one of four possible instrument 
conditions:
• When the status indicator is OFF (and power switch light is ON), the 
module is in aprerun condition, and is ready to begin an analysis.
• A green status indicator, indicates the module is performing an analysis 
(run mode).
• A yellow indicator indicates a not-ready condition. The module is in a 
not-ready state when it is waiting for a specific condition to be reached or 
completed (for example, immediately after changing a setpoint), or while a 
self-test procedure is running. 
• An error condition is indicated when the status indicator is red. An error 
condition indicates the module has detected an internal problem which 
affects correct operation of the module. Usually, an error condition requires 
attention (for example, leak, defective internal components). An error 
condition always interrupts the analysis.
• A flashing yellow status indicator indicates that the module is in its 
resident mode. Call your local service provider for assistance upon 
observing this error condition.
• A flashing red status indicator indicates a severe error during the startup 
procedure of the module. Call your local service provider for assistance 
upon observing this error condition.
