Features and Components
A. Electrode Banana Jacks:
Insert the test leads from
the optional 5 pound electrodes here.
B. Electrode Toggle Switch:
Toggle the switch to
INTERNAL to measure with the parallel electrodes
located on the back of the Surface Resistance Meter.
Position the switch to EXTERNAL to measure with
optional 5 pound electrodes (not included).
C. Resistance Measurement LEDs:
The resistance is
measured in ohms and read as 10
X
±1/2 decade where
X is the range illuminated on the meter.
D. Parallel Electrodes:
Ensure that the electrode toggle
switch is set to INTERNAL when choosing to take a
measurement with these electrodes.
E. Test Switch:
Use this switch to make a surface
resistance measurement. Push and hold until one of
the resistance measurement LEDs remains illuminated.
F. Low Battery LED:
Replace the battery when this
battery illuminates during use. Do not use the Surface
Resistance Meter when this LED illuminates.
G. Battery Compartment:
Remove the cover to allow
access to the 9V battery compartment.
Operation
USING THE PARALLEL ELECTRODES
Measure Resistance Point-to-Point (Rtt) on the
Surface
1. Do not clean the surface.
2. Remove from the surface only those items that
might interfere with the test. ESD sensitive devices
shall also be removed.
3. Place the Surface Resistance Meter on the most
commonly used area of the surface. The parallel
electrodes should be 2” away from any edge and
3” away from any grounded point. If the most used
area is not obvious, use two points near the center
of the surface.
4. Toggle the electrode switch located at the top of the
Surface Reistance Meter to INTERNAL.
5. Push and hold the test switch until the measurement
is displayed on one of the Resistance Measurement
LEDs.
6. Perform additional measurements by placing the
electrode on the most commonly used or worn area.
NOTE: When taking multiple measurements, allow
1-2 seconds between measurements. Pushing the
test switch too quickly will result in an error.
If the measurement is outside acceptable limits, clean
the surface with an ESD cleaner containing no insulative
silicone such as Reztore® Surface & Mat Cleaner,
and re-test to determine if the cause of failure is an
insulative dirt layer or the ESD worksurface material.
