(v) The responsiveness of the probe should be tested at at lElast 4 depths within the transducer's range, and with the probe moving both up and down to those depths. 2.2.9. Download data. Depending on the analysis method chosen, the file can either be processed for viewing and manipulation by 'DATMAN' or printed and attached to manually taken records. C2.3 ANALYSIS To determine the system's Over-range performance. Accuracy : Accuracy, Response Time and A highly accurate, consistent and reliable measurement system is ideally required to provide check data from which the accuracy of the system under test can be determined. until such a system is acquired, the manual depth measurement procedure outlined above is the best available and can provide an accuracy of lOmm. For the purpose of this test, the "error" of a logged reading is the difference between the logged reading and the manual reading for that time. This means that the validity of the test is de?endant on the accuracy of the manual readings. This in turn depends on the care taken in setting up the test, in taking and timing individual readings and in keeping readable records of dates, serial no.s and readings. l'Jaximum error alone is inadequate as an accuracy parameter any system which depends on transduction of a physical quantity to an electric signal ~s prone to a variety of c.'lllses of error , Ivhich may not show up in anyone short
