9. Appendix: test cable checking
Qulon-12ns is equipped with special cables with
clips utilizing four-wire (Kelvin) connection. At the negli-
gent treatment - for example, a detachment from the
device by pulling by a cable, they could be damaged. If
you have any doubts about cables, it is possible to
check them up, using a digital tester as follows.
A. Attach cable to Qulon-12ns.
B. Disconnect halves of both clamps from each
other (for example by installing a piece of cardboard or
plastic between halves).
C. Switch tester to resistance measurement
mode.
G. Connect tester to the halves of black
(negative) clamp - the tester should show resistance to
the order of 0.65 Mohm.
D. Connect tester to the halves of the red
(positive) clamp - the tester should show resistance at
least 2 MOhm or no contact.
E. Connect the halves of clamps (half crocodile
clips) to each other — remove insulators, placed before.
J. Connect tester between the black and red
clamps - tester should show resistance to the order of
0.25 Mohm.
