Electrostatic discharge (ESD) is the release of stored static electricity that can damage electrical circuitry. Static electricity is often stored in your body, and discharged when you come in contact with an object with a different potential. The ESD wrist strap safely channels this electricity from your body to a proper ground.
| Warning Before working on a system that has an on/off switch, turn OFF the power and unplug the power cord. |
 | Caution The SwitchProbe device is no longer grounded after you remove the power supply. Therefore, you must ground to something other than the chassis, such as a different chassis or another piece of equipment that is plugged in and grounded. Make sure the equipment having a grounding type plug is properly grounded. |
Use an ESD wrist strap whenever you open a chassis, particularly when you will be handling circuit cards and appliques. To work properly, the wrist strap must make good contact at both ends—with your skin at one end, and with a proper ground at the other.
To use the ESD wrist strap correctly, follow these steps:
Step 1 Ensure that the equipment is properly grounded.
| Caution Make certain that you are not in contact with grounded objects other than through the wrist strap. |
Step 2 Turn the chassis power switch OFF.
Step 3 Unplug the power cord.
Step 4 Make sure the wrist strap is grounded.
Step 5 Remove the wrist strap from the bag and note the following:
Step 6 Snap the cable fastener at the end of the coiled ground cord onto the wrist band.
| Caution A one megaohm resistor is located in the wrist strap ground cord. Do not remove the resistor. If it becomes damaged, replace the ground cord immediately. |
Step 7 Slip the wrist band firmly around your wrist for a snug fit.
Step 8 Connect the alligator clip to the device that you are using as a ground.
Figures 1 and 2 show the front and rear panels of a small (PB6) SwitchProbe device.
