Features and Components
4. Use one 5 pound electrode on the other test lead
and place it at the center of the surface.
5. Set the Test Voltage Button to AUTO. Press and
hold the the TEST button until the measurement is
displayed (see Figure 3).
6. Perform additional measurements by placing the
electrode on the most commonly used or worn
areas.
CAUTION: If there is a current limiting resistor in the
worksurface and the worksurface resistance is lower,
the measurement will primarily be the resistance of the
resistor. It is recommended to measure RTT particularly
if the material color is black.

ohms.
B. Resistance Property LEDs:
Color-coded LEDs that
provide quick-check resistance indicators.
C. Test Button:
Hold this button down to operate the
Analog Surface Resistance meter.
D. Low Battery LED:
Illuminates when the battery
power drops to 4.0V (±0.1V).
E. Test Voltage Button:
Test voltage will automatically
switch from 10V to 100V when set to AUTO. Test
voltage will stay at 10V HOLD when set to 10V.
Operation
Compliance Verification Test Procedure Guideline
The ESD Association lists test procedures and
troubleshooting tips in Compliance Verification ESD
TR53.
NOTE: The test kit can be used to measure RTG and
RTT of shelves, garments, floor and cart worksurfaces
using test procedures similar to worksurfaces and foot
grounders.
MEASURE WORKSURFACE RESISTANCE TO
GROUND (RTG)
1. Do not clean the surface.
2. Remove all ESD sensitive items from the surface
and items that might interfere with the test.
3. Connect one lead banana plug to ground.

MEASURE WORKSURFACE RESISTANCE POINT-TO-
POINT ON THE SURFACE (RTT)
1. Do not clean the surface.
2. Remove all ESD sensitive items from the surface
and items that might interfere with the test.
3. Use two 5 pound electrodes and place them 10"
apart on the most frequently used area of the
surface (2" from any edge, 3" from any groundable
point).
4.
If the most used area of the surface is not obvious,
use two points near the center of the surface.
5. Set the Test Voltage Button to AUTO. Press and
hold the TEST button until the measurement is
displayed (see Figure 4).
