G. If either red “Fail LO” or red “Fail HI”
LEDs light and the audible indicator sounds,
the wearer should check the foot grounding
device immediately.
H. Repeat steps C through G with other
foot.
Free Standing Test Fixture
Assembly and Operation
(Model 41203)
Figure 8. The 41203 Free Standing Test
Fixture
The 41203’s rugged steel pedestal tube is
powder coated in a non-conductive white
finish that helps to prevent false readings if
contacted by skin or loose smocks.
Assembly
A. Remove 3 screws from baseplate.
B. Position pedestal on the baseplate with
the Tester mounting bracket pointing away
from the operator. Attach pedestal to
baseplate using the three screws provided.
Tighten with hex wrench provided.
C. Open the compartment and attach the
snap connector to the included 9 volt
battery. Attach poster to the wall at eye level
in front of the Tester location.

D. Install the Tester on the bracket by
aligning keyholes on the back of tester with
mounting studs on bracket. While pushing
up on thumb screw, insert the mounting
studs into the keyholes and slide the tester
down. See Figure 10.

and securing Tester to bracket
E. Install the 4" banana plug connection to
“FOOTPLATE” jack on the side of the unit.
F. Insert ring terminal behind thumb screw.
Twist the thumb screw clockwise to secure
the tester to the bracket.
WRIST STRAP TESTING
This test verifies that a continuous path
between the operator, wrist strap, and
ground cord exists.
A. While wearing the wrist strap, plug the
banana plug end of the cord into the jack on
the face of the unit.
B. Press rocker switch toward “WRIST
CORD”.
C. Press the test button so that the unit
activates. Hold down for 2-3 seconds.
Note:
DO NOT TOUCH ANY OTHER
METAL WHILE PERFORMING TEST.
D. Lighting of the green “PASS” LED
indicates that the wrist strap and ground
cord assemblies are functioning properly.
E. If either red “FAIL LO” or “FAIL HI”
LEDs light and the audible indicator sounds,
the wrist strap wearer should check the wrist
strap assembly immediately.
TESTING FOOT GROUNDING
DEVICES
When testing conductive shoes or heel
straps, test each foot separately to ensure
proper operation and complete protection.
A. Press rocker switch toward
“FOOTPLATE”.
B. Place one foot on the plate. If the floor is
conductive, lift the foot you are not testing
off of the floor during this test. Make sure
there is no cord plugged into the “WRIST
CORD” jack.
C. Press the test button so that the unit
activates.
D. Lighting of the green “PASS” LED
indicates that the foot ground assemblies are
functioning properly.
E. If either red “Fail LO” or red “Fail HI”
LEDs light and the audible indicator sounds,
the wearer should check the foot grounding
device immediately.
F. Repeat steps A through C with other foot.

Calibration
The models 41201, 41205, and 41203 are
calibrated to NIST traceable standards. We
recommend that calibration is performed
annually to ensure that the Tester is
operating within limits. Due to its dual
circuit design both test circuits of the
Combo Tester must be calibrated
individually.
ESD Systems.com offers a calibration unit
that is specifically designed to simplify the
calibration procedure. This unit is sold as
item 41230. The Calibration Unit comes
calibrated to NIST traceable standards. For
additional information on the 41230, ask for
Technical Bulletin PS-2006.
