Abstract : The report contains development testing of panel meters. The nine were broken down into three groups, each group having a different taut band material. Within each group was one 40 microamp, one 100 microamp, temperature compensated, and one 100 microamp RFI treated. With minor changes to correct problems occurring during thermal shock, moisture resistance and high shock, it is felt all the program requirements will be met except linearity. Temperature compensation has been finalized, the change is expected to vary from 0 to 1% for the 100 microamp units and from 0 to 2% for the 40 microamp units at the various test temperatures. A series of RFI tests has indicated that metal mesh windows provide more attenuation than conductive windows. (Author)
