8. If the Rc LED does not illuminate following the pre-measurement checks, this indicates that the
instrument fuse has ruptured.
9. If the Rc LED illuminates solidly following the pre-measurement checks, this indicates that a two-
terminal measurement can be made.
10. The two-terminal resistance reading will be indicated on the scaleplate as shown in Figure 17.
Figure 17: example two-terminal resistance reading
Note:
The test voltage used to make the two-terminal resistance reading is a.c. and may not be suitable for
continuity testing according to some local regulations.
No resistance reading is possible if the ground noise voltage exceeds 100 V.
