If the measurement is outside acceptable limits, clean
the surface and re-test to determine if the cause of
failure is an insulative dirt layer or the ESD worksurface
material. NOTE: Use an ESD cleaner containing no
insulative silicone (i.e. Desco 10435 Reztore Antistatic
Surface and Mat Cleaner).
Seating - “The recommended electrical resistance range
for seating is less than E9 ohms as tested in accordance
with ANSI/ESD STM 12.1. This value should be during
acceptance testing, installation and periodically thereafter.”
(see ESD TR20.20 section 5.3.5.3 Testing)
Garments - “ESD TR53 describes periodic verification test
methods and trouble shooting for garments. The sleeve
to sleeve resistance test should be made to ensure proper
resistance range through the entire garment. Alternately,
the garment while worn can be tested using a wrist strap
tester.” (ESD Handbook ESD TR20.20-2008 section
5.3.13.3.1.7 Periodic Verification Testing)
Maintenance
The area surrounding the cable jacks at the top end of the
meter should be wiped with a clean cloth moistened with
alcohol to remove skin oils that will accumulate and affect the
accuracy at high resistances. The frequency of cleaning will
depend on usage; once a month would be a good starting
point.
Per ANSI/ESD S4.1 “Clean the electrodes with a minimum
70% isopropanol-water solution.” Make sure conductive
pads are dry prior to use.
The Analog Surface Resistance Meter requires little
maintenance, and there are no user serviceable parts. If
your unit requires service beyond cleaning the electrodes
or replacing the batteries, please contact Desco Customer
Service.

RECOMMENDED FREQUENCY OF PERIODIC
COMPLIANCE VERIFICATION OF INSTALLED
PRODUCTS
The ESD Association lists test procedures and
troubleshooting tips in Compliance Verification ESD TR53.
NOTE: “The frequency of periodic testing is normally
specified in corporate operating procedures. …The frequency
of testing is driven by the amount of risk exposure that can
occur between tests. For example, what is the quantity of
product handled between test periods?” (See ESD Handbook
ESD TR20.20)
A GUIDE FOR PERIODIC TESTING
Worksurface, Carts, Shelves - at least quarterly (see ESD
TR20.20 section 5.3.1.13 Periodic Tests)
Footwear - “Incoming inspection on a lot sampling basis
should be performed for all static control footwear.” (see
ESD TR20.20 section 5.3.3.4 Testing)
Floor - “In some cases, a simple electrical resistance
test with a megohmmeter may suffice. In others, a static
charge generation test may be required. The frequency of
testing is also a consideration. Some materials, such as
floor finishes, may require more frequent testing because
of their lack of permanency.” (see ESD TR20.20 section
5.3.4.15.1.4)

electrodes to measure RTT of worksurfaces (place
electrodes 3 feet apart for flooring)
