Workstation Monitor Checker
An easy-to-use, self-contained and portable system to verify the
operation of your workstation monitors.
The Workstation Monitor Checker was designed specifically to verify
the proper operation of your dual wrist strap, workstation and ground
monitors. The Checker simulates the proper resistances and signals
to check for the correct response and verify that the monitors are in
compliance with your facilities specifications.
Although the Checker was designed to work with 3M monitors such as
3M
™
WS Aware, Iron Man Plus, 3M
™
Ground Master and 3M
™
Ground
Man, it can also be used to verify the operation of most other monitors
on the market today.

Workstation Monitor
The 3M Workstation Monitor 724 continuously monitors the resistance
of the operator and worksurface ground connections. The monitor
uses a reliable resistance method that actually includes the operator’s
skin resistance to determine if the system is operating properly. If
the operator’s resistance exceeds pre-set levels of 10 megohm or
35 megohm, or the wiring connections exceed 3.7 megohm, audible
and visible alarms are triggered. The unit will also warn of potentially
dangerous low-resistance situations. A switch allows the user to select
either a 9 V or 16 V test voltage, and 10 megohm or 35 megohm
resistance setting.
The monitor uses the light, compact dual conductor wrist strap
(purchased separately; see page 11). Dual conductors provide the
resistance circuit that is monitored, as well as grounding redundancy.
If one conductor fails, the other will still function to prevent sensitive
components from being exposed to static.
The Workstation Monitor 724 monitors a visitor to the workstation or
a second operator. In addition, the loudness of the alarm is adjustable.
A quick connect/disconnect 3M
™
Remote Input Jack 732 comes with
the Workstation Monitor.
The worksurface ground resistance circuit of the 3M workstation
monitor indicates a malfunction when the ground loop resistance
exceeds 3.7 megohm. To determine if your mat is within this limit,
perform the following procedure using an ohmmeter.
Measure the resistance between the snap on the mat, where
you intend to connect the 3M
™
Monitor/Table Mat Replacement
Cord 2380, and the ground point for the mat. Be sure the mat is
connected to ground.

Monitor Verification Kits
The 3M Verification Kits 724VK and 725VK were designed to check the
wrist strap input resistance ranges of the 3M
™
Workstation and 3M
™
Wrist Strap Monitors 700 Series. The 3M Verification Kit 790VK contains
hardware items for connecting to the 3M
™
Static Monitor 790, that are
recommended when performing the verification procedure. Use of this kit
allows for reliable connections to the Monitor 790. In addition to this kit,
a DC power supply and resistance substitution box are required (supplied
by user). See instruction manual for complete details.

Dual Conductor Remote Input Jacks
The 3M Remote Input Jack 732 may be purchased as a replacement
part for the 3M

Workstation Monitor 724. It provides two phone jacks
— one for the primary worker and one for use by visitors to the work
area. The 3M
™
Remote Splitter Kit 733 may be purchased for use in
conjunction with the Workstation Monitor 724. It offers the versatility
of grounding and monitoring two workers at independent workstations
that are in close proximity. The units feature a quick “connect/
