• Ratio-on and Ratio-off calibration data is measured and recorded at
the same time.
• The 7500-NTU standard does not have to be measured during
calibration if turbidity less than 4000 NTU will be measured. Push
CAL/Zero
after the 4000 NTU standard is measured to complete the
calibration procedure.
• Clean the USEPA filter assembly before doing a primary calibration,
or at least every 3 months (which is the USEPA-recommended
primary calibration interval).
