Instrument LED Indicator

The LED indicates a variety of instrument operation conditions, such as calibration mode, and operation. Below is a complete list of all conditions reported by the LED.

Operation Mode (Green Light)

• Solid Green Light—self test passed and instrument is ready for use with defined strip.

• Slow Flashing Green Light—strip reading in progress (strip being read).

• Fast Flashing Green Light—strip reading attempted but the wrong strip was inserted, or strip skewed during reading.

Calibration Mode (Yellow Light)

• Solid Yellow Light—instrument calibration was entered, ready to start calibration with next button press.

• Slow Flashing Yellow Light—instrument calibration in progress (strip being read).

• Solid Green Light after Yellow Light—instrument calibration was successful and instrument is ready for use.

• Fast Flashing Yellow Light—instrument calibration failed, re-read calibration strip. If error persists, clean instrument and calibration strip (see Section Three). If error still persists, contact your Service epresentative.

Error/Reset Mode (Red Light)

• Solid Red Light—and error was detected, the self test failed. Verify correct power supply is used. Turn power off, reapply power and see if condition is corrected; if not, contact Service Representative.

• Solid Green or Yellow changing to Red—an instrument reset is in progress. To initiate a reset, press and hold the button, the LED changes from Green or Yellow to Red. While the LED is Red, press button again (within 10 seconds). The LED changes to Green and the reset is performed, reinstating the factory defaults. If the second button press is not performed when the LED is Red, the instrument will time-out, causing the LED to change to Green and the reset to be aborted.
