'rile commuEication software is more complicated than would be desired. Some ambiguity does exist in the menu options and is only supported by vague explanation in the handbook. An alternative to the 2.5mm audio plug and socket would be desirable as communications problems have been encountered apparently due to poor contact of the connection . .< ii) Cherryville Logger. The communications software and hardware is similar to the Torrens Logger. Comments as per Torrens Logger. The size of the logger does not permit it to be secured wi thin a boretcead of less than 250rrur, diameter. An external housinog would therefore be required in the majority of cases. 4.2.3 Other Considerations i i) Wesda1:a Logger. The logger has a memory capacity of 64000 bytes. rhis will enable storage of approximately 20000 data pairs, or 12 readings daily for 4.5 years. The logger logs at a minimum of 12 hourly (ie. twice daily) regardless of specified logging interval. continuous operation for over one month was not generally and achieved and accuracy testing limited success in faithful data connector is c:msidered inadequate transfer in the majority of interrogation procedure does information to the user. indicated variability retrieval.

This will have a major control on the timing of field checks. Testing has not been adequate to determine battery consumption chara,cteristics / venting efficiency/resistance to moisture
