PRF-922B Miniature Two-Point Probe Set
a. Hold the PRF-922B ver cally, and apply pressure to compress the electrodes, making posi-
ve contact with the insulated surface.
b. Ac vate 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 1.0x10 12 ohms, or greater.
(2) With other instruments, they should provide a HIGH resistance indica on. For
example, 10 12 or >10 12 ohms when using the ESD Check ESI-870 Resistance Indicator
(3) or approximately 10 11 ohms when using the PRS-801 Resistance Meter
C. PRF-922B Veri fi ca on Using the PRV-913B Two-Point veri fi ca on fi xture
1. Connect the BNC/banana adapter to the wide range, resistance measurement instrument.
Flange side of dual banana should be connected to the Posi ve (+) power terminal. This applies
test voltage to the 10 outer ring electrodes.
2. Remove PRF-922B Probe Cover (Figure 5).
3. Posi on PRF-922B ver cally into the PRV-913B Two-Point
Veri fi er with its spring loaded pin electrodes making direct
contact with the Veri fi er’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 posi oned in the
PRV-913B Two-Point Veri fi er. Resistance should be 1.0x10 6
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. Posi on the PRF-922B ver cally directly over test
area and lower it un l the spring loaded center
electrode makes direct contact with the material
under test.
3. Apply su ffi cient pressure on the probe un l the
center and outer spring loaded electrode are
par ally compressed while in contact with the test
material.
