Temperature and Relative Humidity during 15 second
electrification period making numerous measurements and
calculations to the display mantissa i.e LED displays 8 and
LCD displaying 7.14 as mantissa = 7.14 x 10E8 ohms or

Surface Resistance Kit
Description
The Surface Resistance Test Kit is a portable, accurate,
and versatile instrument designed to measure point to point
resistance (Rp), resistance to ground (Rg), and surface
resistivity. It is designed to perform test methods described in
EN 61340-5-1 Annex A. Features include:
• Resistance measuring accuracy ± 10% (E11 and greater
± 20%)
• Resistance range <1.0 x 10E3 ohms to >10E12 ohms
• Open circuit voltages of 10 and 100 ± 5%
• Electrification period of 15 seconds
• Electrodes 2.27 kilograms ± .06 kg with 50-70 durometer
conductive pads
In addition, the Meter measures ambient temperature and
relative humidity.
The Surface Resistance Test Kit (or its Meter) is referenced
and designed to be used to make measurements in accordance
with the test methods in EN 61340-5-1 Annex A Resistance
Measurement Test method:
• A. 1 Floor, working surface or storage rack working surface
• A.2 Seating
• A.3 Garments
• A.5.4 Gloves, finger cots and tools (Neither 20 mm plates nor
clip connectors provided)
Versatility:
Measures Rp, Rg or Resistivity (requires optional Resistivity
Attachment, item
)
• Quick Checks - Surface resistance exponent number
illuminates immediately i.e. 8 = 10E8 ohms or 100,000,000
ohms
Model Description
Power
Surface Resistance Test Kit
2 x AA Batteries
Meter and Attachment
2 x AA Batteries
Resistivity Attachment
N/A
A pair of Test Leads (item
) can be bought separately.
The Charleswater
purchased separately also.
Inspection
Remove the meter from the carton and inspect for damage.
Each Surface Resistance Test Kit should include the following:
1 Protective carrying case
1 Meter
2 Test leads
2 2.27 kilogram electrodes
2 AA alkaline batteries
1 Certificate of NIST calibration
Properly store the Meter and component assemblies when not
in use.
ESD protective products should be tested:
A. Prior to installation to qualify for listing in user’s ESD control
plan approved ESD protective materials (see EN 61340-5
paragraph 9.3.2 Qualified protective items)
B. During initial installation
C. For periodic audits of installed products as part of EN
61340-5-1 paragraph 9 Quality responsibilities
In addition: Per EN 61340-5-2 paragraph 9.4 “When a new EPA
is established, or an existing EPA is reconfigured, it should be
thoroughly checked by the ESD co-ordinator and a certificate …
issued.”
Electrification Period
The Surface Resistance Test Kit provides the proper
electrification period of 15 to 20 seconds per ESD EN
61340-5-1, after numerous readings and calculations
are executed, then displays surface resistance mantissa
measurement (Note: most analog type meters display
measurements instantaneously).
