Operating Your System

Fig. 2

To operate the 3M™ Model 725 Wrist

Strap Monitoring system, attach the

monitor's (6 ft.) ground cord with

dual conductor ground clip to a

suitable ground.

Caution

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.

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 Model

725 Monitor. 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.

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 was unaware of these events.

**Resistance values are ±15%
