A reading for the calibration drift check of a water quality monitor sensor for specific conductance, during a site visit. The Code indicating whether the reading is for calibration or recalibration. The date and time of the specific conductance check or calibration reading. The theoretical value of the standard solution, in units of the parameter. The code identifying the type of the standard, KCl or NaCl. The lot number of the standard solution. The expiration date of the standard solution. Was this this reading for the conductance standard that was used for recalibration? The water temperature during the specific conductance check or calibration, in degrees Celsius. The specific conductance read during the specific conductance check or calibration, in microsiemens per centimeter at 25 degrees Celsius. The percent error between the specific conductance standard and the check or calibration reading.
