6.2 ESD Guidelines for HPMM and IOP Cards
Static discharge effects
When inserting an HPMM or IOP card into a card file and following normal ESD procedures, other cards
in the card file, HPMM or IOP, can go
OFFNET because of electrostatic discharge. It does not result in
damage to any of the components on the card when an ESD wriststrap is worn, but does affect subsystem
integrity. A procedure has been developed to discharge the card using a 10 megaohms Static Discharge
Probe.
ESD kit
Honeywell has available an ESD kit, part number 30185H, that contains the following components.

10 megaohm static discharge probe

Static discharge wriststrap (AESOPS Inc. Model 31531)

Static discharge cord, 15 feet (AESOPS Inc. Model 30204)

Static discharge cord, 6 feet (AESOPS Inc. Model 30205)

Antistatic work surface with bag
Building a static discharge probe
A static discharge probe can be built by placing a 10 megaohm resistor in series with any available probe
or clip lead.
