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-914B, 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-914B 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.

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

measure approximately 1.0 ohm, or less.

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-914B 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.

In the case where the Prostat PRS-801 is the measurement instrument, it should  measure  

1.0x10

14

 ohms, or greater.

C.  PRF-914B Verification Using the PRV-913B

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 ap
