  Lauren JonesAug 8, 2025
  If you receive a 'Result out of calibration range' warning on your XOS Measuring Instruments, it typically means that either the wrong calibration curve was used for the measurement, or the sample itself is incorrect. To resolve this, remake the sample, validate that you're using the correct calibration curve for the measurement, and then re-measure the sample.

  If your XOS Measuring Instruments provide an inconclusive measurement error, it's often due to an unusual spectrum or insufficient sample in the cup. Try creating a new sample and re-measuring to see if the error disappears. If it persists, attempt to measure a validation sample.

  An internal error on your XOS Measuring Instruments, accompanied by a prompt to ensure the door is closed, usually means the sample lid wasn't closed at start-up. To resolve this, open and close the sample lid, then restart the device by pressing the power button. If the error continues, contact XOS Technical Support.

Why do XOS Measuring Instruments show error IOP temp high?
- B
  bryanjackAug 28, 2025
  The '[ERROR[ERROR_IOP[Error IOP temp High]]' message on your XOS Measuring Instruments indicates a high internal temperature. This is often caused by blocked vents, fan failure, or a hot ambient temperature. To address this: 1. Ensure there are at least 6 inches of clearance around the analyzer. 2. Inspect the fan filter; if it's dirty, clean or replace it.

What to do if XOS Measuring Instruments tube is hot?
- L
  Lisa KellerSep 2, 2025
  The message 'Tube is hot' on your XOS Measuring Instruments indicates that the x-ray tube has overheated due to continuous use. The analyzer will not measure until the tube cools below 60°C. Stop measuring and wait for the message to disappear, which will happen automatically when the tube temperature decreases. Pressing OK will not clear the message while the tube temperature is close to 65°C.
