14.4.2.1. WORKING AT THE INSTRUMENT RACK
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.
14.4.2.2. WORKING AT AN ANTI-ESD WORK BENCH
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. Never lay them down on any non-ESD
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.
14.4.2.3. TRANSFERRING COMPONENTS FROM RACK TO BENCH AND BACK
When transferring a sensitive device from an installed TAI analyzer to an anti-ESD
workbench or back:
