Screen tension A manufacturer of high-resolution video terminals must control the tension on the mesh of fine wires that lies behind the surface the viewing screen. Too much tension tears the mesh, and too little allo wrinkles. The tension is measured by an electrical device with output readings in millivolts (mV). Here are the tension readings from a rando sample of 20 screens from a single day's production: 269.5 297.0 269.6 283.3 304.8 280.4 233.5 257.4 317.5 327
