Immediately before use in the the field probe(s) will be calibrated for pH, specific conductivity, and turbidity. The probe will be recalibrated again for the same parameters upon returning from field use. Other parameters will be calibrated according to the frequency and approach described in Table 9. Allowable drift is also described in Table 9. If drift exceeds that shown in the table, data will be flagged as estimated and equipment maintenance and calibration procedures will be re-evaluated with action taken to correct, clean, or replace equipment or parts as needed.
