PRF-922B, PRF-922A-B & PRV-913B Two-Point Miniature Concentric Ring Fixture Set

I. Introduction & Description

The PRF-922B Miniature 2-Point Resistance Fixture Set accurately measures surface

resistance of small areas. It consists of a PRF-922B Two-Point Resistance 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-801 Resistance System, PRS-812 Resistance

Meter, or PSI-870 Resistance Indicator, and an

insulated test bed. This instrument and fixture

combination provides direct point-to-point resistance

measurements in ohms across the surface of small

parts and assemblies.

A. PRF-922B Two-Point Resistance Fixture

Description

This precision fixture consists of 2 gold

plated, spring-loaded contact electrodes

spaced 0.250 inches (6.35mm) apart,

center-to-center. The electronic quality gold plated contact probes are 0.1-inch

(2.54mm) in diameter, and are supplied with conductive synthetic rubber contact

boots, which are 0.125-inch (3.18mm) diameter. The conductive 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 0.9 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 0.32

inches or larger.

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

consistent contact pressure during measurement.

4. Overall size of the PRF-922B is 0.50 inches in diameter by 7.0 inches (178

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

PRF-922B Standard accessories include protective cover, one RG-174

cable, a BNC/banana adapter and instructions

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.

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 touching the spring-loaded contacts when they are

energized.

a. If used with the PROSTAT PRS-801 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 metallic part 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 operation 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.

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.

This manual displays Cautions and Warnings alerting the user to hazardous operation

and servicing conditions. CAUTION or WARNING headings throughout this publication

flag this information, where appropriate. Follow all Caution and Warning instructions at

all times.

3. Once the cable and BNC adapter are installed the PRF-922B is ready for continuity

test, verification and use (Fig 4).

4. To use, connect dual banana converter to wide range, resistance instrument with ¾

inch terminal 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, and 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, making 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-801 is the measurement instrument, it should

measure approximately 1.0 ohm, or less.

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

example, <103 ohms when using the Prostat PSI-870 Resistance Indicator, or

<104ohms when using the Prostat PRS-800 analog Megohmmeter.

2. Repeat the above procedure using the clean insulated surface (Black, labeled

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

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

making positive contact with the insulated surface.

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

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

measure 1.0x1012 ohms, or greater.

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

example, 1012 or >1012 ohms when using the Prostat PSI-870 Resistance

Indicator, or approximately 1011 ohms when using the Prostat PRS-800 analog

Megohmmeter.

NOTE: To remove BNC connections, apply slight

pressure and twist connector counter clockwise.

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 2 point verifier with its spring

loaded pin electrodes making direct

contact with the Verifier’s gold plated test

segments. (Figure 6)

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 2-point Verifier.

Resistance should be 1.0x106 ohms 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 electrodes makes direct contact with the material under test.

3. Apply sufficient pressure on the probe until the spring-loaded electrodes are partially

compressed while in contact with the test material, and the outer housing “stops”

contact the material under test.

IMPORTANT NOTE:

The outer housing “stops” help ensure consistent probe pressure with the material’s

surface and that the springs are not fully compressed against their stops. This will

provide more reproducible measurements.

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

Association S11.11 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 <1.0x106 ohms, use 10 volts.

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

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

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

Mode 2 [Ohms] display). AUTOMATIC Mode will control test voltage, resistance range

adjustment and electrification period automatically.
