Audible Alarm Tones
For wrist strap malfunctions the 3M
Workstation Monitor Model 724 indicates
a different tone for each operator – a
continuous tone for #1 operator and a fast
chirping beep for #2 operator. The volume of
the wrist strap alarm is adjusted by selection
of the internal DIP switch #1. For work
surface malfunctions, a slow chirping beep
is made. This alarm sound is turned on or off
by selection of DIP switch #2. Switch #1 and
#2 are accessible through a slot located in the
bottom of the chassis.
Work Surface Monitoring
The Workstation Monitor Model 724 monitors its
connection to ground and the grounding of a 3M
ESD work surface. A loop resistance is measured
from the monitor, through a 3M Monitor/Table
Mat Cord 2380D to the work surface (Section 2),
across the conductive layer of the work surface,
through the grounding wire of the work surface
to an electrical ground and finally back to the
monitor through the Workstation Monitor Model
724 grounding wire. If the resistance of the loop
exceeds 3.7 Megohms the work surface high red
lamp (M) will illuminate and all green lamps will
be extinguished. If DIP switch #2 is in the ON
position (Figure 4) the audible alarm will activate.
If no ESD work surface is to be monitored, the
Monitor/Table Mat Cord 2380D and the ground
wire of the Workstation Monitor Model 724 must
be connected to an electrical ground (Section
3). This is done to ensure that the Workstation
Monitor Model 724 is providing a ground connection for the operators. Again, if
the loop resistance exceeds 3.7 Megohms the work surface high red lamp (M) will
illuminate and the alarm will activate if selected.

NOTICE
The grounding wire from the work
surface and the ground wire from
the 3M Workstation Monitor
Model 724 must be attached to
separate electrical grounds. The
work surface monitoring function
is active any time that the power
supply for the monitor is plugged in.
NOTICE
Disconnect the 3M Monitor/
Table Mat Cord 2380D to prevent
possible damage to the 3M
Workstation Monitor Model 724
before testing the resistance of the
work surface with a high voltage
megohmmeter.
