However, if there are cther cables or tapes downhole, the probe cable may have to be joined to the measuring tape, in a way which allows free movement of the tape relative to the cable. One way of doing this is to attach rings to the cable at approximately 3m intervals and run the tape through them. If a few probes O.re being tested simultaneously, then all their cables must be taped together, and kept separate from the measuring tape. When setting transducers at any depth, the weight of the probe must be on the tape. 2.2.6. synchronise watch and logger, synchronisation. 2.2.7. Procedure for performing stages I and II (i.e. accuracy testing) check (Note thai: stage I must be completed before II is begun) (i) start: logger - using a small logging interval (e.g. 5 sees); (ii) Place probe at selected depth intervals, leaving at each depth for at least 1 minute. Record times of probe movement (time probe moved from previous depth and ':ime it arrived at new depth) I so two times are recOJ:ded for each depth, between which the probe was at that depth. (iii)Repeat at same depths, with transducer moving up and down through the full range at least tvlice. Readings for both increasing and decreasing probe depths must also be recorded for the greatest and leasi~ depths selected. Have probe beyond end readings and back to get 2 readings (1 up,1 down) at same depth. E.g., after having taken the O.Sm
