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.
