(iv) The manual records should therefore include two times for each selected depth, for at least 4 runs for stage I, and at least 2 runs for stage II. 2.2.8. Procedure for performing stage III (i.e" responsiveness testing) (i) set the logging interval as small as possible, and recheck the time synchronisation of the logg~)r . watch and (ii) Move the probe up and do,,;n by at least 3m as quickly as possible. stop the movement suddenly at a predetermined time. (The person controlling the probe should stop it moving when told to do so by the person taking the time records - timing accuracy to a second should be achieved). Keep the probe at the same depth for at least 2 minutes. {iii)The stop times chosen must be related to the logging interval, in the case of systems with minimum logging intervals over 5 seconds. The movement to a part:Lcular depth should be repeated 3 times stopping one, three and five seconds before the logger takes a re.ading. E. g., if the minimum interval available is 10 seconds, and the system is logging on even minutes, the stop times must be HH:MM:09, HH:MM:27, HH :J,ll4: 55 etc. (iv) Note that in stages I and II, times are recorded as depths are reached, whereas in stage III, the probe plac'~ment is performed to a time schedule.
