electrode continuity, as described in point f.
(3) If no continuity indication appears, change the test lead
connection to the other BNC/Dual Banana adapter receptacle
and repeat the procedure.
(4) If no continuity indication appears, clean the electrode surface with 70%
solution of IPA, test the PRS-801 or PRS-812 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.)
f. Remove the PRS-801 or PRS-812 test lead from the BNC/Dual Banana adapter
and install it in the BLACK OUTER RING electrode receptacle located on the
