Note: Operators may complain that the alarm

is sounding too often until they learn to

adjust the wrist band to fit securely or apply

an approved skin moisturizer on a frequent

basis. Please remember that the monitor is

informing you that the operator is exceeding

the established static control requirement for

resistance to ground when wearing a static

protective wrist strap assembly. These alarms

alert the operator when sensitive electronics

are possibly being exposed to static electricity.

Prior to incorporating the wrist strap monitor

into your static control process, the operator

could be unaware of these events.
