Hello! In an earlier Pioreactor software, the self-test “Reference photodiode is correct magnitude” is failing due to a software bug. There’s nothing wrong with your photodiodes or hardware. You can ignore this failing test.
This is now fixed in version 23.4.14, released April 14th. Any images downloaded or software updated after this date will have the fix.
Hi Cameron,
After I updated my cluster to the 25.4.5 the self-test for the “Reference Photodiode is correct magnitude” keeps failing for all my units. I tried to play with the ir_led_intensity, but it still fails. OD reading seems to be working, only the test fails.
Ah you’re right - there’s a silly type bug here that I should have caught. You can ignore the failed test for now.
