Technical Report WRD92039 Viewed at 15:07:17 on 29/07/2010 Page 55 of 192. 4. DNrA ACQUISITION SYSTEMS 'fhis section presents an appraisal of the equipment tested and its applicability to the percieved role within this organisation. 'rhe results presented wi thin this section were obtained from the tests described in section 3. 4.1 Test Pumping Prototype TWO proto":ype systems were trialled for the logging of test pumping data. These were based on the MINDATA 3500 and the 'fORRENS loggers. Each were coupled to the suite of transducers described in section 3. 4.1.1 Field Test Appraisal iil Mindata 3500 Data Logger inputl ... This logger performed uninterrupted operation and was friendly" for most applications. (6 channel, 4 analogue reliably in considered regards to to be "user specific tests were not performed to determine recording accuracy I nor the effect of variable and extreme temperature. It is recommended however, that at least the latter be examined under controlled conditions as it is possible that exposure to temperatures approaching its specified upper limit of 60C will occur. The accuracy of the logger is stated to be 1: 20000 and cannot be checked with c,vailable equipment. Thus it has been assumed that the accuracy of results is dependent on the transducers available. A number of anomalies were detected in the logger software which should b(" addressed. These include The logger is not capable of operating at the highe,st specified recording frequency (ie. 1 second) if there are :Eour channels activated. This is presumed to be due to the minimum "power up" time of 300 micro seconds required for each transducer. The "power up" operation is performed in SUCCElssion for each transducer. A 4 second period was found to be adequate.
