Page 27: Visual Inspection
Use, Maintenance, and Care of the Devices Visual Inspection Figure 4-1 ESD Protection Setup Visual Inspection Visual inspection and, if necessary, cleaning should be done every time a connection is made. Inspect mating surfaces for dirt, dust, foreign particles, or scratches, which can degrade device performance. - Page 28 Use, Maintenance, and Care of the Devices Cleaning the Mating Plane Surfaces These electrostatic effects can damage the device.

Page 29: Connections
Use, Maintenance, and Care of the Devices Connections Connections Good connections require a skilled operator. Slight errors in operator technique can have a significant effect on measurements and measurement uncertainties. The most common cause of measurement error is poor connections. The following procedures illustrate how to make good connections. -
