When working on the analyzer while it is in the instrument rack and plugged into
a properly grounded power supply
1. Attach you anti-ESD wrist strap to ground before doing anything else.
 Use a wrist strap terminated with an alligator clip and attach it to a bare
metal portion of the instrument chassis.
 This will safely connect you to the same ground level to which the
instrument and all of its components are connected.
2. Pause for a second or two to allow any static charges to bleed away.
3. Open the casing of the analyzer and begin work. Up to this point, the closed
metal casing of your analyzer has isolated the components and assemblies
inside from any conducted or induced static charges.
4. If you must remove a component from the instrument, do not lay it down on a
non-ESD preventative surface where static charges may lie in wait.
5. Only disconnect your wrist strap after you have finished work and closed the
case of the analyzer.
When working on an instrument of an electronic assembly while it is resting on a
anti-ESD workbench
1. Plug you anti-ESD wrist strap into the grounded receptacle of the work
station before touching any items on the work station and while standing at
least a foot or so away. This will allow any charges you are carrying to bleed
away through the ground connection of the workstation and prevent
discharges due to field effects and induction from occurring.
2. Pause for a second or two to allow any static charges to bleed away.
3. Only open any anti-ESD storage bins or bags containing sensitive devices or
assemblies after you have plugged your wrist strap into the workstation.
 Lay the bag or bin on the workbench surface.
 Before opening the container, wait several seconds for any static charges
on the outside surface of the container to be bled away by the
workstation's grounded protective mat.
4. Do not pick up tools that may be carrying static charges while also touching
or holding an ESD sensitive Device.
 Only lay tools or ESD-sensitive devices and assemblies on the conductive
surface of your workstation.
preventative surface.
5. Place any static sensitive devices or assemblies in anti-static storage bags or
bins and close the bag or bin before unplugging your wrist strap.
6. Disconnecting your wrist strap is always the last action taken before leaving
the workbench.
