In reference to the test pumping role, the logging interval, durc!tion of testing I downloading procedure and memory and data storage requirements need to be addressed. The logger will permit downloading of data at any time, facili tating a::1Y requirement to process data during a test. Al though logging is required to be stopped in order to do this, the downloading process is not likely to be in excess of 2 minutes. On recoIlli-uencement of logging I subsequent data is added to the Existing data set so that a complete record of the test remai::Js intact. All data is retained in the memory module until it:s erasure is specifically requested. Resetting of the logger through the menu will clear all input parameters including the calibration, time, logging interval and all memory stored. No power consumption figures consumption of are available at this stage, power has not been detected however I abnormal during any test. An indication of power consumption at the maximum rate (ie. 4 channels active) needs to be obtained to ensure uninterrupted logging. Al though battery status is automatically logged once at midnight, it is important that personnel constantly be aware of it since the functionality of the logger and communication with it is dependent on a threshold of 11.9 volts. Manufacturer support has been considered to be good. iii) Torrens Loaaer. This logger was not trialled as extensively as desired due to the limitation on the available (single set) ancillary equipment and in the majority of cases, tests \-lere performed using the Minda ta logger. However, e}"'Perience in its general performance can be drawn from the "hydrcgraphic" section. The transducers used for the Minda ta logger were adapted for use with this logger via a "crossover" plug. only minor software "bugs" were detected during testing. These ,lere eliminated after contact with the manufacturer. Further field testing is required to assess its performance
