Resistance Checks
Follow the manufacturer’s instructions for measuring the resistance of your
workstation components. That’s the only way to be sure your workstation’s doing its
job of carrying static charges to ground.
Measure the mat’s resistance with a test kit for static control surfaces. Get the kit
from the GSA Advantage website:
From the home
page, do a search on the test kit’s part numbers:
701C.
Discharge Control Program
Measuring resistance in the wrist strap is especially important. The strap takes more
wear and tear than any other part of your workstation. Measure it at least daily. Get a
wrist strap tester with NSN 4940-01-388-1693. Order it on a DD Form 1348-6 from
RIC SMS and put “NSN not on AMDF” in the REMARKS block.
The wrist strap has a resistor to protect you against high-voltage shocks. If the
resistance is too low, the strap can’t protect you. Too much resistance means the strap
can’t draw static electricity away from your body. Either way, you’ll need to replace it.
Have your workstation tested for resistance from the surface of the table or ±oor
mats to ground. That takes special testing equipment and special support. Contact
your local TMDE support folks or a CECOM LCMC LAR for help.

When you rotate the antenna
180°
in
either
direction,
the
antenna cable wraps around the
locking plunger. That’s the knob
sticking
out
from
the
antenna
mount. The plunger sticks out just
far enough for the cable to get
tangled around it. If you rotate the
antenna too far, it puts stress on the
tangled cable. With enough stress,
the cable breaks loose from the
THOR III, and the RF connector
pulls apart from the cable.

operating your AN/PLQ-9(V)1
countermeasure receiver-
transmitter (also known as THOR
III): Take care when handling
the antenna and the receiver-
transmitter antenna cable. If you
don’t, the cable could break loose
from the THOR III’s J5 connector.
It happens this way:
