What does a "PASS" indication on a wrist strap tester mean?

• A. The wrist strap needs replacement
• B. The wrist strap and cord are both functional
• C. The wrist strap is disconnected
• D. The wrist strap is not suitable for ESD protection

Answer: (B)

A "PASS" indication on a wrist strap tester signifies that both the wrist strap and the cord are functioning correctly. This means that the wrist strap has an adequate level of resistance and that it is effectively grounding the wearer, thereby helping to prevent electrostatic discharge. Ensuring that the wrist strap is in working order is crucial for ESD protection, especially in environments sensitive to static electricity, as it guards against damage to electronic components. In contrast, other options point to issues with the wrist strap. For instance, if the wrist strap needs replacement, it implies a failure to meet necessary standards, which would not result in a "PASS" indication. A disconnected wrist strap would not complete the necessary circuit for testing, leading to a different error status. Lastly, a wrist strap deemed unsuitable for ESD protection would also fail to achieve a "PASS" indication, as it wouldn’t meet the prescribed safety levels for such environments.
