Warning:Hazardous voltage
To reduce the risks associated with hazardous voltage:
1. Read,understand and follow all safety information contained in this user guide for
installation and use.Retain this guide for future reference.
2. Use the power adapter in an indoor dry location only
3. Replace power adapter if damaged
4. Do not modify or attempt to service the power adapter
This user guide covers ESDMAN 001-9502.This monitor has two input jacks for
monitoring impedance and voltage on a dual conductor wrist strap.It also monitors one
metal ground in a workstation.The monitor operates from either a North American or
universal AC power adapter.These systems are typically installed on a machine with
multiple tools or on a work bench used for sensitive electronic assembly or repair.
The systems must be installed as specified in this user guide and are intended for use
The systems must be installed as specified in this user guide and are intended for use
in an indoor commercial/industrial environment.The systems have not been evaluated
for other uses or locations.
Read,understand and follow all safty information contained in this user guide prior to
installation and use of this workstation monitor.Retain this guide for future reference.

The workstation monitor can be used at work areas or locations to monitor the ground
impedance of metal ground connection in process tools in semiconductor,disk drive,flat
panel,electronic equipment manufacturing and other environments.Ground impedance
monitoring can be used for up to two points for metal ground,such as within a tool.
The workstation monitor can also be used to monitor the impedance to ground and
voltage level on two persons wearing dual-wire wrist straps.The unit incorporates green
and red LED’s and audible alarm.
Ground impedance monitor-continuously monitors for ground impedance on one
Ground impedance monitor-continuously monitors for ground impedance on one
channel that is connected to one process tool.
ESDMAN 001-9502 provides continuous monitoring of operator connection to the
monitor via loop resistance check of operator’s physical presence using dual-wire wrist
strap.
Voltage on person wrist strap monitor—The workstation monitor has one additional
feature that allows continuous monitoring for excessive voltage on each operator.
1. To reduce the risks associated with environmental contamination:
Dispose of the monitors and power adapter in accordance with local,state,and federal
regulations.
Unit must be checked periodically to vefity each monitor circuit is functioning
correctly.
2. To reduce the risks associated with improper equipment grounding:
Verify that the electrical ground point is a known good ground(the ESDMAN 001-9502
Verify that the electrical ground point is a known good ground(the ESDMAN 001-9502
does not have the capability of verifying that the ground point is a suitable ground)Do
not use the monitor for the.Electrical grounding of equipment(these monitors only
verify proper ground connection)
Connect a ground wire on the back of the unit to a known good ground point
3. To reduce the risks associated with environmental contamination:
Unit must be checked periodically to verify each monitor circuit is functioning correctly

Connect the circular plug of the AC/DC adapter into the power jack on the back of the
unit.
1. Attach 18 AWG wires to unit as described below.Strip back vinyl insulation at each
end of wires to approximately 1/3 inch(8mm).Twist the stranded wire on each end
before inserting wire into each connector location.
2. Attach the ground wire to the “GND”connector on the back of the unit.Insert a small
blade screw driver into the orange slot above.Gently push inward and insert the
stripped wire fully into the hole in the green connector.Hold the wire fully in and
release the screw driver to allow the wire to catch.
3. Attach the impedance monitor wire to the ground line”G1”connector on the back of
3. Attach the impedance monitor wire to the ground line”G1”connector on the back of
the unit.Insert the wire as described above.

By default,the ESDMAN 001-9502 workstation monitor is set at the factory to 10 ohms
alarm level.If you wish to change this alarm level to your specification ,follow the
procedure that sets the impedance alarm level for the G1 channel.
Repeat the steps above in section 05
Right after the beeps stop,continue pressing the “set” button until the impedance level
is matched as shown in the table on the following page.
When the beeping stops,the four left most LED’s(see photo below)will allow for the
When the beeping stops,the four left most LED’s(see photo below)will allow for the
setting of the resistance value.The G1 red LED is at upper location;the green LED is at
lower location.Select the ground resistance value by pressing the “set” button to
advance the resistance limit.Turn the LED’s on or off as indicated in the table on the
following page.
Not pressing the “set” switch for about seven seconds after selecting causes the limit
value to be saved and normal operation started.

Equipment required:For this test,the workstation monitor should be disconnected from
the monitored ground.Use the ESDMAN 001-1001,to prevent misreading,the ESDMAN
001-1001 incorporates a color coding systems to divide the display into 3 groups to
indicate ohms,Kilohms and Megohms.Special attention has been given to reliability.A
special multiple gold contact switch arrangement ensures that back-up contacts are
always available to take over should a contact fail.

1.Attach two banana plugs into red and blue jacks respectively,the other end terminal
is 3.5 mono channel,let it connect to monitor OP1 or OP2.Then adjust the resistance of
ESDMAN 001-1001 to 10M,OP1 or OP2 should be green,it indicates monitor works
correctly.Once resistance of ESDMAN 001-1001 at 11M,OP1 or OP2 should remain red.
2.Attach two banana plugs into red and blue jacks respectively,one terminal connect
2.Attach two banana plugs into red and blue jacks respectively,one terminal connect
ground,and the other end terminal connect any jacks of GND of the monitor.Adjusting
ESDMAN 001-1001 resistance box,if resistance value is lower than 10 M,monitor GND
LED remain green,however if resistance is larger than 10 M,monitor GND LED
illuminates red.
Connect the ground wire to an electrical good known ground point.
Connect the ground monitor input to identify locations in a process tool.
Make sure to connect the monitor input to different physical locations than those points
used for their grounding.

1. ESDMAN 001-9502 workstation monitor features:plug the dual conductor ground
cord of the wrist strap into the jack on the front of the unit.If the wrist strap is worn
properly,a green LED will come on;otherwise the red LED will be on.In order to provide
a good ground connection,the wrist strap must be worn tightly-the green light on the
workstation monitor is an indication of that.
2. If for whatever reason,while properly connected,the operator developed excessive
2. If for whatever reason,while properly connected,the operator developed excessive
body voltage(in excess of 5V in any polarity),the green LED may still be on,but the red
LED will blink without an alarm sound.
3. No LED is on if a dual conductor ground cord is not plugged into the jack.
