Surface Resistance Test Kit
Operation and Maintenance
Figure 1. Item
Description
The Surface Resistance Test Kit is a portable, accurate,
and versatile battery operated instrument designed
to measure resistance between two points (RTT) and
resistance to ground (RTG) in accordance with ANSI/ESD
S4.1 including:
• Resistance measuring accuracy ± 10%
(E11 & greater ±20%)
• Resistance range <1.0 x 10E3 ohms to >10E12 ohms
• Open circuit voltages of 10 and 100 volts ± 5%
• Electrification period of 15 seconds
• Electrodes (two) 5 pounds ± 2 oz with 50-70 durometer
conductive pads
In addition, the Meter measures ambient temperature (in
degrees Fahrenheit and Celsius) and relative humidity.
Voltage set to “Auto”, will measure at 10 volt automatically
switching to 100 volts if material being tested is >10E5
ohms. No switching test voltage is necessary.
The Surface Resistance Test Kit is referenced and
designed to be used to make measurements in accordance
with the test methods in:
• Worksurfaces - ANSI/ESD S4.1 Worksurfaces
• Compliance Verification - ESD TR53 - Resistance
Measurements
• Floors - ANSI/ESD S7.1- Resistive
Characterization of Materials Floor

Resistivity Attachment, item
•
Quick Checks
- Surface resistance exponent number
illuminates immediately i.e. 8 = 10E8 ohms or
100,000,000 ohms
•
Compliance Verifications of Installed Products
- Surface resistance exponent number illuminates
immediately and displays Temperature and Relative
Humidity during 15 second electrification period making
numerous measure ments and calculations to then display
mantissa i.e. if LED displays 8 and LCD displaying 7.14
as mantissa = 7.14 x 10E8 ohms or 714,000,000 ohms
