Comments
This instrument is not unique in its content of ESD (electrostatic discharge) sensitive components. Most modern electronic
designs contain components that utilize metal oxide technology (NMOS, SMOS, etc.). Experience has proven that even small
amounts of static electricity can damage or destroy these devices. Damaged components, even though they appear to function
properly, exhibit early failure.
