3. Once the cable and BNC adapter are installed the PRF-912B is ready for continuity
test, verification and use
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, then confirms its ability to measure high resistance.
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.
a. Hold the PRF-912B 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, <10
3
ohms when using the Prostat PSI-870 Resistance Indicator, or
<10
4
ohms 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-912B 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 1.0x10
12
ohms, or greater.
(2) With other instruments, they should provide a HIGH resistance indication. For
example, 10
12
or >10
12
ohms when using the Prostat PSI-870 Resistance
NOTE: To remove BNC connections, apply slight
pressure and twist connector counter clockwise.
