What to do if Status LED is off or on continuously on NIRx All in One Printer?
- S
  Samantha DoughertyAug 15, 2025
  If the Status LED on your NIRx All in One Printer is off or continuously on, it could be due to a data connection problem. First, try reconnecting the USB cable. If that doesn't work, try using a different cable or USB port. Also, ensure that the necessary software and drivers are correctly installed on your computer. Finally, check the device's presence and function in the ‘National Instruments Automation Explorer.’ If the device is listed but inactive, remove it, restart your PC, and reconnect the NIRSport.

What to do if all sources show maximum gain and low signal for the same detector channel on NIRx Measuring Instruments?
- J
  Joe BlackAug 27, 2025
  If all sources show maximum gain and low signal for the same detector channel on NIRx Measuring Instruments, it indicates a low signal from the detector. Check the optical coupling of the affected detector to the skin, part hair if needed, apply coupling gel, and apply gentle pressure through the outer cap or bandage. Also, check the connection of the affected fiber optic cable to the instrument.

What to do if a large number of channels go to highest gain setting on NIRx Measuring Instruments?
- D
  Denise SellersAug 30, 2025
  If a large number of channels or all channels go to the highest gain setting on NIRx Measuring Instruments, it could indicate low or no signal in all channels. Check the connection of the LED POD, ensure the LEDs are blinking during scanning, verify the connection of the fiber optic bundles, check the proper placement of probes on the subject's head, and inspect for damage on the LED illuminator or fiber optic cable.

What to do if all detectors show maximum gain for the same source on NIRx Measuring Instruments?
- J
  Jessica WallaceSep 5, 2025
  If all detectors show maximum gain for the same source on NIRx Measuring Instruments, it is likely due to a low signal from the source. Check the optical coupling of the affected source to the skin, part hair if needed, apply coupling gel, and apply gentle pressure through the outer cap or bandage.

What to do if there is no or low reading for one source at one wavelength on NIRx Measuring Instruments?
- P
  Priscilla ButlerSep 12, 2025
  If there is no or low reading for one source at one wavelength on NIRx Measuring Instruments, it might be due to damage to the LED driver or LED optode. Restart the instrument, and without performing calibration, start a scan and point the affected LED directly into a detection fiber tip or detector channel port. If it's working correctly, there should be a stable reading for both wavelength plots in the scan screen (display set to raw data).
