Digital Surface Resistance/Resistivity Test Kit
Operation and Maintenance
Description
Figure 1. Charleswater Item No. 19770
The Digital Surface Resistance/Resistivity Test Kit is a
portable instrument designed to measure resistance
between two points (RTT), surface to ground (RTG), and
surface resistivity in complete accordance with EOS/ESD
Association Standard S-4.1. This unit is suitable for
evaluating the electrical properties of ESD protective work
surfaces and flooring products.
Figure 2. Parallel Resistivity Electrodes on bottom of meter.
The meter has two parallel probes on the bottom of the
case which measure surface resistivity. These parallel
electrodes allow for quick and easy testing of a variety of
surfaces and materials without the use of external probes.

In addition to the Association Standards listed previously,
anyone testing the electrical properties of ESD protective
surfaces should also obtain copies of:
MIL-HDBK 263A
EIA-IS-5-A
ASTM-F-150
ASTM-D257
EN 100015
These standards are available from the agencies who
produce them. If you need help in obtaining these
documents contact our customer service department at
781-821-8370.
Inspection
Remove the meter from the carton and inspect for damage.
Each unit should include the following:
1 Protective carrying case
1 LCD display meter
2 Test leads
2 5-pound weighted electrodes
1 Grounding clip
1 AC adapter/charger
1 PP-5032 Tech Brief
1 Rechargeable battery
Properly store the meter and component assemblies when
not in use. Do not charge battery unless it is fully
discharged. Doing so will reduce the life of the battery
.
