If the reading is less than the instrument range,
make sure that the instrument cap is fully
installed over the cell holder. Measure a blank.
If the blank reading is not zero, set the
instrument to zero again.
If the reading is more than the instrument
range, identify if there is a light blockage in the
cell holder. Dilute the sample. Do the test again.
For factory-calibrated programs, the maximum
and minimum values always equal the factory-
calibrated values and cannot be changed.

When an E-1 or E-2 error occurs on a measurement, the display shows

occurs while the instrument is set to zero, set the instrument to zero again.
