Wells have color, but absorbance values seem low.
a. Incorrect filter used for measurement and/or
reference wavelength.
Check wavelength used in analysis. Read plate in single
wavelength mode at all wavelength to verify that the proper
filter was used. The measurement wavelength should
produce the highest absorbance.
b. The best measurement wavelength filter for the
substrate in use has not been installed in the
filter wheel.
Check references for the substrate you are using, or
determine the best measurement wavelength by analyzing
the substrate product on a scanning spectrophotometer.
Custom filters are available from 400 to 750 nm.
8.
c. The filters have been switched in the wheel. Check that the filters are installed in the correct position.
9. “Printer error” displayed. Check for paper jam. Install the printer paper correctly.
10. “Battery error” displayed. The internal battery is almost dead. Contact your local
Bio-Rad office.
11. The following messages are displayed.
“Memory error” ,
“Calendar error” ,
“LCD hardware error” ,
“Printer error”,
“Light level error” ,
“D/A conversion error” ,
“A/D conversion error”
“EEPROM error”,
“USB error”
Contact your local Bio-Rad office if these problems persist.
