MODEL 09-0102: 2-POINT PEN PROBE
INTRODUCTION
The WENVYTM 09-0101, 09-0102 and 09-0103 Pen
Probes work with most megohm meters, electrometers
and other high potential resistance meters in most
Resistance Kits for measuring Surface Resistance and
Volume Resistance of materials with physical dimensions
too small for regular concentric ring or other probes. The
size, portability and construction make these probes
convenient for auditing small samples of materials in the
field and yet their design specifications make these
instruments precision enough for laboratory environments.
09-0101, 09-0102 and 09-0103 Pen Probes use spring
loaded electrodes with conductive rubber boots to ensure
intimate contact with hard/irregular surfaces and reduce
contact resistance. All electrodes are field-replaceable,
spring-loaded, pogo-pin type ATE-quality probes that are
made of beryllium copper with minimum 60 micro-inch
hard gold.
The 1-Point Pen probe can be used for measuring volume
resistance of small planar material sample per the
requirements of ANSI/ESDA 11.12 or measuring
resistance to ground of materials or component on a piece
of equipment.
Direct point-to-point resistance measurements with
WENVY 2-Point Pen Probe, 09-0102, generally conform
to the guidelines as outlined in the ANSI/ESDA 11.13 2-
Point Resistance Measurements.
The 2-Point Pen probe uses a thin line BNC coaxial cable
with inner source and outer sense connections to
minimize reading errors due to electrostatic interference.
The BNC to banana jack adapter allows connection to
most popular meters in the market.

CAUTIONS -- WARNINGS
As with any electrical device, use proper electrical
precautions to avoid personnel shock.
The 09-0101, 09-0102 and 09-0103 Pen Probes operate
with power input from the megohm meters at 10 to 100
volts, and is capable of delivering an annoying shock to
any person touching it.
Although the current capability is limited, a distinct
HAZARD EXISTS in the person's reaction to the shock.
To avoid personnel shock, do not touch the electrodes or
contact boots on the 09-0101, 09-0102 and 09-0103 when
power is applied to the probes.

Volume Resistance Measurement for Planar materials
Introduction:
Volume resistance measurements determine if the
material has electrical conducting properties through the
bulk of the sample. This test will measure resistance from
top surface to bottom surface of the sample. There are
several possible current paths that the user should
understand and determine which one or combinations of
which give the final reading as shown on the schematic
below by Ben Baumgartner (ESDiscovery 2000).
As shown above, the test current can go along the top
surface, around the edges, through the bulk material at
various points, within the material or across the bottom
surface before reaching the bottom probe.
To ensure that the edges do not contribute to the reading,
it is best to cut the sample into one smaller piece so that
none of the outside vertical edges exists. In this way, the
only way the current can flow is down, not going around
along the surfaces.

Page 12
Procedures:
1. Place sample to be tested on a conductive
platform such as stainless steel or copper plate.
2. For best result, the platform should be thick
enough to accommodate a hole for a banana jack.
3. Connect the negative (-) terminal to the test
platform.
4. Plug one end of the coiled cord, provided with the
09-0101 kit, to the 1-Point Pen Probe.
5. Connect the other end of the coiled cord to the
positive (+) terminal of your megohm meter. If
your meter comes with cables that end with a
banana plug, use that cable and plug into the 1-
Point Pen Probe.

Page 13
6. Make sure that the conductive rubber boot is
secure on the probe pin.
7. Hold the Pen Probe vertically and place the
rubber tip on the sample.
8. Apply pressure and compress the pogo pin until
the probe body is about 1/8” of an inch from the
rubber boot. This would provide the sufficient
pressure for correct contact force.
9. Apply to test voltage from your meter to read the
sample volume resistance per ANSI/ESDA 11.12.
10. Note: Volume resistance is shown as the reading
from the meter (in ohms) divided by the material
thickness and shown in ohm-cm or ohm-inch.

Resistance to ground measurement for small piece
parts
Introduction:
This test will measure resistance from various points on
the top surface of the piece part to the conductive platform
that the bottom surface of the sample is sitting on. The
purpose of this test is to determine the ability of the piece
part to dissipate electrostatic charge from it surface to a
fixture or tool. The same possible current paths as the last
section and all of them will contribute to the charge
dissipation characteristics of the sample, as shown on the
schematic below by Ben Baumgartner (ESDiscovery
2000).
In this case, however, we want the edges to contribute to
the readings. For best result, the conductive platform
should be larger than the sample.
Procedures: Test procedure is the same as that for planar
materials.

MODEL 09-0101: 1-POINT PEN PROBE
Resistance to Ground Measurement for Equipment
Introduction:
Resistance to ground measurements for equipment
determines if the material installed in the production
equipment has the ability to dissipate electrostatic to the
equipment ground. This test will measure resistance from
machine parts to the equipment chassis ground. It is
recommended to measure all machine parts within 12”
ESD sensitive product handling path per ANSI/ESDA
10.1, Automated Handlers.
For metal machine parts, an ohmmeter or the ohmmeter
function of a DVM can be used.
For coated or non-metallic machine parts, a megohm
meter with applied voltage of 10 volts or 100 volts as
appropriate can be used.
Procedures:
1. Connect the negative (-) terminal of your meter
(ohmmeter or megohmmeter) to the equipment
chassis ground.
2. Connect the negative (-) terminal of your meter
(ohmmeter or megohmmeter) to the one-point Pen
Probe.
Note: When using the megohmmeter, the probe tip
may be energized up to 100 volts. Make sure that
sensitive products are not placed nearby the probe tip.

Page 16
Do not touch the probe tip with your hand. Do not
touch the probe tip to sensitive products.
3. For metallic machine parts: Use an ohmmeter.
Remove the conductive rubber tip for the probe tip.
4. Set the ohmmeter to auto range or to the lowest range
of ohm reading.
5. Touch the bare (gold color) probe tip to various points
on metallic machine parts.
6. Apply pressure and compress the pogo pin until the
probe body is about 1/8” of an inch from the top of the
pin contact. This would provide the sufficient pressure
for correct contact force.
7. Record measurements.
Note: A properly grounded metallic machine part
should have its resistance to ground reading less than
1 ohm.
8. For coated or non-metallic machine parts: Use a
megohmmeter. Make sure that the conductive rubber
tip is installed.
9. Set the applied voltage to 100 volts. Touch the probe
tip to non-metallic machine parts.
10. Apply pressure and compress the pogo pin until the
probe body is about 1/8” of an inch from the rubber
boot. This would provide the sufficient pressure for
correct contact force.
11. Record measurements.
Note: A properly grounded static dissipative or ESD
coated machine part should have its resistance to
ground reading less than 1 x 1011 ohms.

Point-to-Point Resistance Measurement for Materials
Introduction:
Point-to-point resistance measurements for planar
material characterize the ability of a planar (flat) sample to
conduct electricity and electrostatic charge from one point
to another along the top-most layer of the material. For
thick samples with bulk conductivity, the resultant reading
can come from many paths of current flows, as shown
below. (Courtesy Ben Baumgartner, ESDicovery 2000)
This test is designed to check for hot spots on a sample of
a finish product where the NFPA probes (5lbs weights) are
too large to detect or to fit on the sample.
Procedures:
1. Place sample to be tested on an insulative
platform such as plastic or acrylic plate.

Page 18
2. Connect one end of the coaxial cable,
provided with the 09-0102 kit, to the 2-Point
Pen Probe.
3. Connect the other end of the BNC cable to the
BNC-Banana Jack adaptor.
4. Plug the RED banana jack to the positive (+)
terminal and the BLACK banana jack to the
negative (-) terminals of your megohmmeter.
If your meter does not comes with banana
receptacle, but has cables that end with
banana jacks, use these cable and plug them
into the BNC-Banana adapter.
5. Make sure that the conductive rubber boot is
secure on the probe pins.
6. Hold the Pen Probe vertically and place the
rubber tips on the sample.

Page 19
7. Apply pressure and compress the pogo pins
until the probe runs against the dead stop.
This would provide the sufficient pressure for
correct contact force.
8. Apply to test voltage from your meter to read
the sample volume resistance per
ANSI/ESDA 11.13.
