FAQ: Our ColorFlex EZ displays a 0040 error code. This is when the white plate is placed on the port during standardization of the sensor. What does this mean and how do I fix it?

Important Notes:

Answer:

The ColorFlex EZ or MiniScan EZ (any model) error code 0040 means there are insufficient signal counts while reading or standardizing.

The error code 0040 shown in the bottom left-hand corner of the ColorFlex EZ or MiniScan EZ display indicates insufficient signal counts were received by the detector. This typically occurs during standardization, mostly on the white tile, but it can occur in reading samples.

Here is how to trouble shoot the issue.

1. Re-standardize and in setting the bottom-of-scale with the black standard, flash the ColorFlex EZ or MiniScan EZ into the room to make sure that the lamp is still active. If there is no flash, then contact HunterLab Support as the lamp appears to have failed.
2. If the sensor standardizes successfully, it is possible that there is an operation error accidentally presenting the green tile at the port during standardization instead of the white tile.
3. Proceed with measurements and continue to monitor the sensor. If the issue is an electronic or lamp problem, the User should contact HunterLab Support (support@hunterlab.com).
4. Have the batteries in the MiniScan EZ been recently charged (if re-chargeable NiMH) or replaced (if AA alkaline)? A low set of batteries on the MiniScan EZ can cause the 0400 or FFFF error to occur.
5. Batteries are not an issue with the ColorFlex EZ as it is AC-powered. However, it is good to pull off the port and make sure that nothing has spilled onto the cover glass below. Wipe with isopropyl alcohol and a Kim wipe.
6. If the lamp flashes during standardization but will not go past the white tile, then go to MAIN MENU > DIAGNOSTICS > SIGNAL COUNTS. Measure the white tile (both sample and monitor channel should be approximately 30,000 counts (would fail at 17,000) and black glass/light trap (sample channel near 0; monitor channel approximately 20,000). Low signal counts could be due to the sphere being coated by dust or a board failure if there are no counts showing.
7. Contact HunterLab Support (support@hunterlab.com) as appropriate.
