Mode Nephelometric (N)
Ranges 0-11 NTU/FNU
10-110 NTU/FNU
Each range can be calibrated with one point per range plus a blank. New calibration points
will replace old calibration points independently for each range. If one range is recalibrated,
the meter will retain the old calibration data for the other ranges. It is recommended that
the meter be calibrated for each range that will be used. The value of the standards chosen
for the calibration should not be at the extremes of the ranges. The meter is auto-ranging
and will automatically select the appropriate range for the sample being tested.
It is recommended that the meter be calibrated daily.
