" Manual or automated tests
" Optional 6-inch plate attachment (Model 287/22C) achieves1:1
correspondence with standard charged-plate monitor test
results
" Saves the test results for ten manual tests or ten automated
test sequences including environmental data
" Integral temperature and relative humidity sensors to capture
environmental data during test
" Test results correlate to standard tests performed using a
charged-plate monitor in accordance with ESD Association
standard S3.1
