Operating Your System
To operate the 3M
™
Wrist Strap Monitor Model 725, attach the monitor’s (6 ft.)
ground cord with dual conductor ground clip to a suitable ground.
Attach a 3M
™
Dual Conductor Ground
Cord to a 3M
™
Dual Conductor Wrist
Band. Place the wrist band on your
wrist and plug the cord into the jack
on the front of the Wrist Strap Monitor
Model 725. Plugging into the jack
activates the monitor and causes it to
emit a short beep and the red lamp
to momentarily flash. If the red lamp
flashes with an intermittent audible
alarm or at any time during use, the
resistance of the wrist strap assembly
is greater than 35 megohms.
**
If
the red lamp and the audible alarm
remain on continuously, check the dual
conductor ground clip connection.
The system is now ready for use.
**Resistance values are ±15%
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.

NOTICE
If you decide not to use the dual
conductor ground clip that is attached
to the monitor’s ground cord in the
way described in this user instruction
manual, observe the following
precaution: Attach each of the two wires
of the monitor’s ground cord to separate
ground bonding points. By attaching the
wires to the same ground but at different
physical locations, the monitor can
check for loose or lost connections.
