Troubleshooting the Instrument
Performance test failed
52 Nicolet iS5 LS User Guide
If an instrument performance test fails, follow these steps:
1. Thoroughly clean the sample windows
2. If the performance test fails again, take the following action depending upon which test
failed:
• If the single beam or 100% T test fails, complete the following in this order and then
repeat the performance test:
– calibrate the laser frequency
– align the instrument optics
– calibrate the sample stage
• If the wavelength accuracy hexadecane test fails, complete the following in this order
and then repeat the performance test:
– Rerun the Calibration Check
new (unopened) source container to make sure the hexadecane is not
contaminated.
– calibrate the laser frequency
– calibrate the sample stage
• If the pathlength hexadecane test fails, run the
calibration fails, complete the following in this order and then repeat the
performance test:
– Rerun the Calibration Check
new (unopened) source container to make sure the hexadecane is not
contaminated.
– calibrate the laser frequency
– align the instrument optics
– run the full stage calibration
NOTICE
• Run the Full (stage) Calibration only if the Quick (stage) Calibration fails.
• Always calibrate the laser frequency
