(1) If proper connection is made to the BNC/Dual Banana adapter
the PRS-801 or PRS-812 will indicate low resistance by full meter deflection.
(2) If resistance is high, change the test lead connection to the other BNC/Dual
Banana adapter receptacle and repeat the procedure.
(3) If no continuity indication appears, clean the electrode with 70% solution of
IPA, test the PRS-801 or PRS-812 and lead connections per its operating
instructions and repeat the procedure. (i.e. Install the supplied shunt and test
the low range. Check the cable & connections as well.)
6. Confirming the Outer Electrode

) through the frame installed BLACK banana receptacle. NOTE:
Review the resistance instrument’s operating instructions before proceeding.
a. Place PRF-911 Concentric Ring fixture on a flat surface with the
electrodes facing UP .
b. Plug one PRS-801 or PRS-812 Resistance Meter test lead into the BLACK
OUTER RING banana receptacle located in the side of the fixture frame.
c. Attach an alligator clip to the second PRS-801 or PRS-812 Resistance
