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
“_.__”. The decimal place depends on the chemistry. If the E-1 or E-2 error
occurs while the instrument is set to zero, set the instrument to zero again.

The flashing value will be 10% over the upper test range limit.
