ANKOM Daisy - Manual (Page 7)

Troubleshooting
(Continued)
Note:
For problems relating to the results of your analyses using the ANKOM DAISY
II Incubator, first check to
ensure the procedures sent with your machine were followed. Some possible variables that may affect
your results are:
- Improper solution concentrates.
- The assay procedure was not carefully followed.
- Oven drying temperatures were too high
(drying temperatures higher than 105
o C may affect results).
- Improper calculation of blank bag correction or using the wrong values in the formula.
- Modifying the settings on the temperature controller.
Problem: The temperature controller reading does not match the actual temperature. The
temperature controller reading is low.
Cause: A bulb is not working, the air flow is obstructed.
Solution: Make sure both heat bulbs are working. Check for an obstruction of hot air flow.
Make sure the Daisy is not under a cold air vent. If this does not solve the problem,
contact
ANKOM Technology.
Problem: Controller reads “no load.”
Cause: A power surge has occurred.
Solution: Reprogram your controller using the controller menu setup sheet in the Appendix B.
Problem: Low Digestibility values.
Cause: Sample size is too large, bags were not acetone rinsed, the rubber baffle spacers fell off
Solution: Ensure that the procedure is followed completely. Reduce sample size to .025
per procedure, check baffle spacers, rinse bags with acetone and thoroughly
dry prior to filling.
