Solution
Remove SD card and switch on the device
again. If the device starts up as usual, replace
SD card.
Contact MACHEREY‑NAGEL regarding how
to proceed.
Remove and check halogen lamp. A defective
halogen lamp can be identified, for example,
by clouding or black discoloration. In this case,
replace the halogen lamp.
In the memory settings, enable the check
mark for "save measurement results".
Contact MACHEREY‑NAGEL regarding how
to proceed.
Manually transfer the data from the evaluation
sheet of the batch into the photometer
and perform the measurement once. For
subsequent measurements, the data are
stored and do not need to be entered again.
Update the software version of the
spectrophotometer or proceed as described
in the previous point and enter the data
manually.
Delete the NANOCHECK LOT in question from
the list with available LOTs by holding down
the LOT in the list for a few seconds and then
confirming the trash can icon. Then manually
transfer the data from the evaluation sheet of
the batch into the photometer and perform
the measurement once. For subsequent
measurements, the data are stored and do not
need to be entered again.
Switch the device off, wait at least three
seconds, and then switch the device back on.
Depending on the message, delete the
measurement data from the measured value
memory. If the message is ignored, the oldest
data set will be overwritten if the memory
is full. Please note that during automatic
overwriting, color references can also be
overwritten.
