  • Page 4: Introduction & Description

    PRF-912B, however, is approximately 1/10th the size of the S11.11 fixture. Based on its size the PRF-912B is often referred to as a “micro probe”. 1. The resistance measurement range of the PRF-912B fixture is 0.9 ohms at <10 volts to 1.0E+12 (1.0x10 ) ohms at 100 volts.
  • Page 5 It provides a specific reference resistance of 1.0 x 10 ohms (±1%) on the two-point side. 2. Properly used, the PRV-913B insures that all PRF-912B & PRF-914B spring loaded test probes make defined contact with the refer¬ence surface. It has the capability of providing a 1-meg- ohm (1.0x10 ohm) reference measurement with a theoretical maximum total variance of 9.5x10...

    A. Use of Measurement Power Supply 1. The PRF-912B 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.
  • Page 7 Never, under any conditions, exceed 500 volts during fixture test or repair. B. Other Operational Precautions 1. Do Not Use the PRF-912B Micro Probe if it fails to function during its continuity inspection test. 2. Do Not Use the PRF-912B Micro Probe if it becomes damaged in any way 3.

    Figure 6: Connect Cable to Banana Con- Coverter verter 3. Once the cable and BNC adapter are installed the PRF-912B is ready for continuity test, verifi- cation and use 4. To use, connect dual banana converter to wide range, resistance instrument with ¾ inch termi- nal spacing.
  • Page 9 1. To confirm general setup and function of the PRF-912B, place the electrodes against a clean metal surface. For example, the plated metal side of the Prostat PTB-920, Dual Surface Test Bed.
  • Page 10 For measurements greater than 1.0x10 ohms, use 100 volts NOTE: For optimal performance and accuracy, use the Prostat PRS-801 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 10: Measurement Illustrations Using the Prostat PRF-912B Fixture IV. Handling & Maintenance 1. Store the PRF-912B in a clean, dry environment with both BNC and Probe covers installed for environmental and mechanical protection. 2. Periodically, remove all spring-loaded test pins. Clean the spring-loaded test probes and Teflon mounting disk with a solution of laboratory grade isopropyl alcohol and a lint-less cloth, or laboratory quality swab.
