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
instrument is in a prerun condition, and is ready to begin an analysis.
• A green status indicator indicates the instrument is performing an analysis
(run mode).
• A yellow status indicator indicates a not-ready condition. The instrument
is in a not-ready state when it is waiting for a specific condition to be
reached or completed (for example, front door not closed), or while a
self-test procedure is running.
• An error condition is indicated when the status indicator is red. An error
condition indicates the instrument has detected an internal problem which
affects correct operation of the instrument. Usually, an error condition
requires attention (for example, leak, defective internal components). An
error condition always interrupts the analysis.
