protection.
NOTE
Check the wrist strap weekly to ensure proper ESD protection.
To test the ESD wrist strap using a DMM:
1 Set the ohmmeter to 2-megohm resistance (see
2 Connect the DMM black lead to the alligator clip at the end of the cord.
3 Contact the DMM red lead to the plate on the inner surface of the wrist strap.
4 Check the resistance reading on the meter. The meter reading must be between 0.80 and 1.20 mega
ohms.
