I. Introduction & Description

The PRF-922B Miniature Two-Point Resistance Fix-

ture Set accurately measures surface resistance of

small areas. It consists of a PRF-922B Two-Point Re-

sistance Fixture assembly, shielded cable equipped

with BNC connectors; probe cover, and a BNC to

male banana adapter.

The PRF-922B works in conjunction with a wide

range resistance instrument, such as the Prostat

PRS-801B Resistance System, the PRS-812B

Resistance Meter or the PAS-853B Wide Range

Ohmmeter, and an insulated test bed. This

instrument and ﬁxture combination provides

direct point-to-point resistance measurements in

ohms across the sur- face of small parts and

assemblies.

A. PRF-922B Two-Point Resistance Fixture Descrip-

tion

This precision ﬁxture consists of 2 gold plated,

Figure 1: PRF-922B Miniature Two-Point Resistance

Fixture Measurement Set.

spring-loaded contact electrodes spaced 0.239 inches (6.08mm) apart, center-to-center. The elec-

tronic quality gold plated contact probes are 0.1 inch (2.54mm) in diameter, and are supplied with

conductive synthetic rubber contact boots, which are 0.123 inch (3.12mm) diameter. The conduc-

tive boots are used to reduce contact resistance between the gold contact probes and materials

under test in certain applications.

1. The resistance measurement range of the PRF-922B ﬁxture is 0.90 ohms at <10 volts to

1.0E+12 (1.0x1012 ) ohms at 100 volts.

2. Contacts are pogo-pin type ATE quality probes made of beryllium Copper, coated with 60 micro

inch of hard Gold. Spacing allows for measurement of items with surfaces approximately 0.125

inches wide having a length of 0.325”inches or larger for planar material.

3. The contact assembly’s outer housing incorporates “stops” that insure consistent contact pres-

sure during measurement.

4. Overall size of the PRF-922B is 0.50 inches in diameter by 6.75 inches (171 mm) long. This

optimal size and shape make the ﬁxture very comfortable and easy to handle. Its outer

housing is made of black anodized aluminum.

II. Cautions & Warnings

As with any electrical device, use proper electrical precautions and measurement practices to avoid

personnel shock. Read this manual in its entirety before attempting to use these products.

PRF-922B Miniature Two-Point Probe Set

Rev. 2 / 3-18-2019

CAUTION

To avoid electrical shock, Do Not Touch the ﬁxture test electrodes, test bed, or exposed

metal BNC connections when power is being applied to the probe.

WARNING

Never exceed the maximum applied operating test voltage of 100 volts

WARNING

Unauthorized opening of ﬁxture or instrument housings, device tampering, or attempted re-

pair will absolutely void product warranty and completely absolve Prostat Corporation of any

responsibility, liability, or other, whatsoever.

A. Use of Measurement Power Supply

1. The PRF-922B is a high performance micro probed designed for use with a maximum input

voltage of 100 volts. As such, it is capable of delivering an annoying shock to any person touch-

ing the spring-loaded contacts when they are energized.

a. If used with the Prostat PRS-801B Resistance System, the current capability of the micro

probe instrument combination is limited to a very low, typically harmless level. However, a

distinct hazard exists in the operator’s reaction to a possible shock.

b. To avoid shock, operating personnel should not touch the electrodes, or any exposed me-

tallic parts of the PRF-922B ﬁxture or cable assembly when power is applied to the probe.

c. The designed operating voltage limit for normal auditing and laboratory measurements is

100 volts. Exceeding 100 volts greatly increases the risk of personnel shock hazards.

d. Only qualiﬁed instrument repair and test personnel should exceed the 100-volt opera-

tion limit, and then do so only under controlled conditions using maximum precautions

against personnel shock.

e. Never, under any conditions, exceed 500 volts during ﬁxture test or repair.

B. Other Operational Precautions

1. Do Not Use the PRF-922B Micro Probe if it fails to function during its continuity inspection test.

2. Do Not Use the PRF-922B Micro Probe if it becomes damaged in any way

3. Only Prostat Corporation authorized, qualiﬁed repair personnel may open PRF-922B or PRV-

913B housing, terminal assemblies, or perform product repair. Unauthorized opening of ﬁxture

or instrument housings, device tampering, or attempted repair will absolutely void product

warranty and completely absolve Prostat Corporation, its employees, suppliers and representa-

tives of any responsibility, liability, or other, whatsoever.

4. Do Not Touch Electrode Surfaces. Electrodes will become contaminated with skin oils and

salts, and may become damaged or rendered inaccurate.

Figure 2: Connect shielded cable to PRF-

922B’s BNC ﬁxture Figure 3: PRF-922B with Cable attached

3. Once the cable is installed the PRF-922B is ready for continuity test, veriﬁcation and.

4. To use, connect BNC end of the cable to a wide range, resistance instrument with ¾ inch termi-

nal spacing. Flange side of dual banana should be connected to the Positive (+) power terminal.

B. Conﬁrming Proper BNC Connections, Continuity & High Resistance Tests

The following conﬁrms proper connections by checking continuity of the micro probe against a

metal plate, then conﬁrms its ability to measure high resistance.

1. To conﬁrm general setup and function of the PRF-922B, place the electrodes against a clean

metal surface. For example, the plated metal side of the Prostat PTB-920, Dual Surface Test

Bed.

a. Hold the PRF-922B vertically, and apply pressure to slightly compress the electrodes, mak-

ing positive contact with the metal surface.

b. Activate the wide range, resistance instrument to obtain a measurement.

(1) In the case where the Prostat PRS-801B is the measurement instrument, it

should measure approximately 1.00 ohm, or less.

(2) With other instruments, they should provide a LOW resistance indication. For

example, <104ohms when using the PRS-801B Resistance Meter.

2. Repeat the above procedure using the clean insulated surface (black, labeled side) of the PTB-

920, or an insulated acrylic plate.

Rev. 2 / 3-18-2019

a. Hold the PRF-922B vertically, and apply pressure to compress the electrodes, making posi-

tive contact with the insulated surface.

b. Activate the wide range, resistance instrument to obtain a measurement.

(1) In the case where the PRS-801B is the measurement instrument, it should

measure 1.00x1012 ohms, or greater.

(2) With other instruments, they should provide a HIGH resistance indication. For

example, 1012 or >1012 ohms.

(3) or approximately 1011 ohms when using the PRS-801B Resistance Meter

C. PRF-922B Veriﬁcation Using the PRV-913B Two-Point veriﬁcation ﬁxture

1. Connect the BNC/banana adapter to the wide range, resistance measurement instrument.

Flange side of dual banana should be connected to the Positive (+) power terminal. This applies

test voltage to the 10 outer ring electrodes.

2. Remove PRF-922B Probe Cover (Figure 5).

3. Position PRF-922B vertically into the PRV-913B Two-Point

Veriﬁer with its spring loaded pin electrodes making direct

contact with the Veriﬁer’s gold plated test segments.

4. Depending on your resistance instrument select either 10V

or 100V test voltage.

5. Measure PRF-922B probe resistance while positioned in the

PRV-913B Two-Point Veriﬁer. Resistance should be

1.00x106ohms ±5%.

D. Basic Measurements Using the PRF-922B Micro Probe

1. Place material to be measured on an insulated test

bed, the clean insulated surface (Black, labeled

side) of the PTB-920, or an insulated acrylic plate.

2. Position the PRF-922B vertically directly over test

area and lower it until the spring loaded center

electrode makes direct contact with the material

under test.

3. Apply suﬃcient pressure on the probe until the

center and outer spring loaded electrode are

4. Select appropriate instrument test voltage and initiate resistance measurement. ESD Associa-

tion ANSI/ESD STM11.13 test voltage guidelines for measuring packaging materials are as

follows:

a. For material resistance measurements of less than 1.0x104ohms, use <10 volts.

b. For measurements of 1.0x104to <1.0x106ohms, use 10 volts.

c. For measurements greater than 1.0x106ohms, use 100 volts

NOTE: For optimal performance and accuracy, use the Prostat PRS-801B Resistance System

in its AUTOMATIC Mode (either Default Mode 1 [Ohms], or Mode 2 [Exponential 1.0EXX/

Ohms] display). AUTOMATIC Mode will control test voltage, resistance range adjustment

and electriﬁcation period automatically.

Figure 7: Measurement Illustrations Using the Prostat PRF-922B Fixture

IMPORTANT NOTE

Adjust probe pressure to insure that the electrode springs are controlling the probe’s con-

nection with the material’s surface and that the springs are not fully compressed against

their stops. This will insure reproducible measurements.

IV. Using the PRF-922B as a One-Point Probe

A. Deﬁne pin continuity as shown in Figure 8. Using a continuity instrument such as a multimeter,

measure from each ﬁxture pin to the BNC/Banana Adapter installed at the end of the shielded

cable. On the PRF-922B 2-Point ﬁxture this determines the probe pin that is connected to the

shielded cable and BNC/Banana Adapter. It also conﬁrms measurement continuity through the

ﬁxture.

Figure 8: Measure pin continuity to the adapter banana to identify active measuring pin.

B. If desired, remove the non-conducting pin from the PRF-922B ﬁxture or PRF-922A-B adapter as

shown in Figure 9. This allows precise positioning of the single active conducting pin.

Figure 9: Removing the inactive pin helps identify point of actual measurement by the active pin.

C. Once pin continuity is determined and connection conﬁrmed, install a conductive rubber boot on

the active measurement pin as shown below as shown in Figure 5. The boot reduces contact resis-

tance and enhances measurement repeatability. It is required by ANSI/ESD STM11.13.

V. Material & Device Measurements with Single Pin Probe

The single pin probe conﬁguration measures eﬀective resistance across and or through a material or as-

sembly. A proper measurement would include placing the material, or device under test (DUT), onto a

clean metal test bed that is isolated from ground, such as the Prostat PTB-920 Test Bed. This insures that

only the material is being measured and the measurement is not aﬀected by voltage variables on ground.

Note that before the measurement, the metal test bed is temporarily grounded to dissipate existing
