preventing further operation of the detector and suspending the absorbance
display. Absorbance output is halted.

includes
remeasurement of all
calibration points.
New calibration
points are compared
to stored information
from the most recent
manual calibration.
If any one of the
points differs by more
than 1.0 nm, the
detector displays this
message. 1. Recycle power to the
