solution is more than the adjustment
limits. Prepare a fresh standard.
• The standard solution is not within the
concentration range that can be used
for standard calibration adjust. Prepare
a standard with a value at or near the
recommended concentrations given in
the procedure.
• Make sure that the concentration of the
standard solution is entered correctly.

If the reading is less than the instrument
range, make sure that the instrument cap
is fully installed on 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.
E-06 Absorbance error The absorbance value is not correct or the
user-entered calibration curve has fewer
than two points. Enter or measure the
absorbance value again.
E-07 Standard value
error The standard solution concentration is
equal to another standard solution
concentration that is already entered in the
user-entered calibration curve. Enter the
correct standard concentration.
E-09 Flash error
The instrument is not able to save data.
Push and hold for 5 seconds to reset
the instrument.
