Prostat PRV-913B Dual Verification Fixture

The PRV-913B’s main purpose is to verify that a Prostat® micro probe resistance fixture – either PRF-912B Miniature Concentric Ring or PRF-922B Miniature Two-Point Probe – physically functions as intended. at is, the spring loaded contacts compress and extend freely and are electrically connected to the probe’s circuitry. Properly used, the PRV-913B insures that all PRF-912B & PRF-922B spring loaded test probes make defined contact with the reference surface inside the verification fixture. If good contact is made, the fixture provides a 1-megohm (1.0×106 ohms) reference measurement (±1%) with a nominal variance of <2%, i.e., 9.98×105 to 1.02×106 ohms.
