A Primer on Electro-Static Discharge
Teledyne API Model 701 Zero Air Generator
8-6 01671H (DCN6051)
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.
8.5.2 Working at an Anti-ESD Work Bench
When working on an instrument of an electronic assembly while it is resting on an anti-
ESD work bench:
1. Plug your 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.
8.5.3 Transferring Components from Rack to Bench and Back
When transferring a sensitive device from an installed Teledyne API analyzer to an Anti-
ESD workbench or back:
1. Follow the instructions listed above for working at the instrument rack and workstation.
