84 TROUBLESHOOTING
Contact DICKEY-john Technical Support at 1-800-637-3302 for persistent
operation errors.
Troubleshooting
Error Probable Cause Corrective Action
0 Sample is not reflective and below the
instrument limit. Clean sample cup or change the sample.
1 Sample is too reflective and above the
instrument limit. Clean sample cup or change the sample.
6 Long-term Reference Drift Error If error does not self correct, clean the reference disk and
aperture glass. If error continues, perform a Reference Log
and Base Gain Setting. This error is informational only and
does not inhibit operation.
7 Short-term Reference Drift Error Possibly a one-time noise disturbance that will not occur
again. Retry analysis. If error persists, could indicate an
unstable instrument or a noisy environment.
8 Sample Analysis Error The filter wheel has lost timing sync. Reselect product and
retry analysis.
9 Reference Analysis Error An error occurred during the stepping of the filter disk and
lost timing sync. Reselect product and retry analysis.
17 Required filters are not installed Wavelengths required for a calibration file is not available on
the unit. The file can be loaded but no analysis is permitted
until suitable wavelengths are installed.
22 Duplicate product labels Product labels must be unique. Use a different product label
name.
Sample ID and/or Customer ID required Result settings has been setup to require an ID. Enter
required ID or change the Results setting requirements.
31 Enhanced gain mode limited Gain limit reached on one or more filters. Any required filter
that has a reference gain of X4 will use X4 in measuring the
sample in Enhanced Gain Mode. This provides an answer
but may be compromised in resolution.
Customer ID is required Customer ID must be entered before proceeding.
Flash drive required A flash drive must be inserted before proceeding.
Invalid File Name An IL700.[PROD].[YYYYMMDD].cal file is created using the
coefficients from the regression program. PROD describes
the product while YYYYMMDD provides dating of the file.
Refer to the Calibration Development section (Calibration
File) for additional information.
47 Optics Bay Error Temperature of 4444 indicates hot temperature and could
indicate that the chopper motor is not functioning and the
heater is turned off. Temperature of 5555 indicates a cold
temperature and suggests a temperature control problem.
Both conditions must be resolved before analysis can occur.
