concentration, it is recommended to careful check the
actual concentration of the calibration solutions to ensure
they correspond to the appropriate calibration range.
Accurate measurement results can be obtained only when
the calibration concentration settings are correct and the
correct calibration solutions are used.
During the automatic range switching and automatic
calibration, attention should be paid to the range of
automatic calibration. The default automatic calibration is
for the range 0-1000 µg/L with 20 µg/L and 200 µg/L
standard solutions since this range (0-1000 µg/L) is most
commonly used. The measurement error caused by the
changes to environmental conditions and other conditions
can be avoided through calibration. It is recommended to

The Calibration Range of 0 µg/L~ 1000 µg/L is for low range; instrument is
0–1000 µg/L
calibrated with the absorbance of long pathlength.
The Calibration Range of 1000 µg/L~ 5000 µg/L is for high range;
1000–5000 µg/L
instrument is calibrated with the absorbance of short pathlength.
Manual
The instrument is calibrated once when calibration is started.
The instrument is calibrated automatically with an interval (such as 24

hours) when Calibration Mode of Interval is selected. The Interval default is
set to 168 hours (1 week).
Double or Single can be chosen. The default is set to Double – two point

calibration should be performed once a week. This setting
can be adjusted under calibration mode: interval frequency.
We recommend using default tolerance settings unless
there is a special case where tolerance needs to be
adjusted.
