factory calibration. The meter will

return to the Turbidity-Without Blank
menu. The calibration has now been
saved and the meter can be used for
testing. The standard should never be
poured from the tube back into the
bottle.
NOTE: For the greatest accuracy during the calibration procedure, be sure that after the
meter is blanked and the blank is scanned as a sample, the reading is 0.00. If not, reblank
the meter and scan the blank again until it reads 0.00. When scanning the calibration
standards as the sample, scan the calibration standard three times removing the tube
from the chamber after each scan and reinserting the tube in the chamber with the same
orientation. The readings should be consistent. Use the last consistent reading to calibrate
the meter. If the readings are not consistent, avoid using an aberrant reading to calibrate
the meter.
