Answer :
Final answer:
Water detector calibration procedure completion is determined by specific readings that confirm the instrument's accuracy, such as ±0.06 pH units for pH meters, and setting 0%T and 100%T for light transmittance meters. However, the exact 'completion' reading can vary based on the type of water detector or measurement instrument used.
Explanation:
The calibration procedure for water detectors involves multiple steps to ensure the accurate measurement of water levels, pH levels, or light transmittance related to water detection and analysis. When calibrating a water detector or any related meters, such as a pH meter or a water level tape, the completion of the calibration process is typically indicated by specific readings that confirm the instrument's accuracy. For a pH meter, the calibration is considered complete and accurate if the meter can measure pH levels with an accuracy of ±0.06 pH units after being calibrated at pH 4, 7, and 10. In the context of water level measurement using a tape coated with carpenter's chalk, the calibration involves observing the change in color on the tape to determine the water level, with no specific meter reading involved. When using instruments measuring the percent transmittance of light in water samples, the instrument is calibrated by setting the transmittance to 0% and 100% (0%T and 100%T), ensuring the detector's measurement range is accurately set. For flow meters and water content analyses, readings may vary depending on the specific device and calibration procedure involved, focusing on the accuracy of the volume or flow rate measured rather than a specific 'complete' reading number.
