ESD control items should be tested:
A. Prior to installation to qualify for listing in user’s ESD
control plan approved ESD control items
B. During initial installation
C. For periodic checks of installed products as part of ESD
control plan compliance verification plan
“A Compliance Verification Plan shall be established
to ensure the Organization’s fulfillment of the technical
requirements of the ESD Control Program Plan. Process
monitoring (measurements) shall be conducted in
accordance with a Compliance Verification Plan that
identifies the technical requirements to be verified, the
measurement limits and the frequency at which those
verifications shall occur. The Compliance Verification Plan
shall document the test methods and equipment used
for process monitoring and measurements. If the test
methods used by the Organization differ from any of the
standards referenced in this document, then there must
be a tailoring statement that is documented as part of the
ESD Control Program Plan. Compliance verification records
shall be established and maintained to provide evidence of
conformity to the technical requirements.
The test equipment selected shall be capable of making the
measurements defined in the Compliance Verification Plan.”
(ANSI/ESD S20.20-2007 section 7.3)
Electrification Period
The Surface Resistance Test Kit provides the proper
electrification period of 15 seconds per ANSI/ESD S4.1,
after numerous readings and calculations are executed,
then displays surface resistance mantissa measurement
(Note: most analog type meters display measurements
instantaneously).
When the Test Button is depressed, the liquid crystal
display (LCD) will indicate:
Temperature in degrees Fahrenheit (tolerance ±5°F,
typical)
Temperature in degrees Celsius (tolerance ±3°C, typical)
Humidity as percentage (from 5% - 95% tolerance, ±10
digits)
Surface resistance mantissa (with exponent displayed via
LED, measurement in ohms)
Measurement being displayed is identified by the illuminated
function LED. The surface resistance exponent (or power of
number) is immediately illuminated and remains illuminated
measuring the range the surface resistance in ohms.

A. LED Displays: Surface resistance exponent is displayed
via light emitting diodes illuminating 1/8" high number.
There are 12 LEDs displaying surface resistance exponent
measurement. They are color coded for quick checks:
Exponent
Color
<3, 3
Red
4, 5
Green
6, 7, 8
Blue
9, 10, 11
Green
12, >12
Yellow
Five Function LED’s identify the measurement being
displayed (see B below).
When battery voltage drops to approximately 2 volts,
the Function LED’s to the right of the red test button will
begin to flash, indicating the need to replace batteries.
B. Display: Mantissa is displayed via 9/16" high liquid
crystal display and provides easy to read resistance (or
resistivity) measurements.
When the Test Button is depressed, the LCD will indicate:
Temperature in degrees Fahrenheit
Temperature in degrees Celsius
Relative Humidity as percentage
Surface resistance mantissa (with exponent displayed via
LED, measurement in ohms)
