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.
