Troubleshooting
ESD non-compliant on work surface & common grounds
•
Verify that the flooring has a RTT value of 10⁵<10⁹
Ohms resistance.
•
Verify that the ESD surface
has a RTT value of 10⁵<10⁹
Ohms resistance. If it does not,
clean and repeat test. If it still does not pass then the surface will need to be replaced.
•
Verify that that the resistance from the surface to the conductive aluminum boot has a
RTG value of 10⁵<10⁹
Ohms resistance. If this RTG value fails proceed to the next step.
•
Check the RTG value of 10⁵<10⁹
Ohms resistance from the common ground on the work
surface to the conductive aluminum boot. If this test passes, replace the ESD surface. If
this RTG value fails proceed to the next step.
•
Check the RTG value of 10⁵<10⁹
Ohms resistance from the ESD wrist strap connection
point to the conductive aluminum boot. If this test passes, replace the ESD surface. If
this RTG value fails proceed to the next step.
•
Check the built-in cable to see if it connected or broken. Replace if damaged. Retest
RTG value.
•
Check ground wire connection to the conductive aluminum boot (this is visible
underneath the bottom shelf). Replace if damaged. Retest the RTG value.
Glossary:
•
RTT =
Resistance to table
•
RTG = Resistance to ground
