Testing Wire in Conduit
There are two methods for testing wire in conduit. You can
test a wire pair or a single wire.
Testing a Wire Pair in a Conduit
To test a wire pair, connect the two test leads to the pair. If
one wire separates from the other for 1 ft or more, the tester
indicates an open at the separation. For example, if the wires
separate after exiting the conduit, the tester indicates an
open at the end of the conduit.
Testing a Single Wire in a Conduit
You can test a single wire by clipping one test lead to the
wire and the other to the conduit. The tester shows the
length up to a fault or to the point where the wire separates
from the conduit by at least 1 ft. For example, if there is a 2 ft
service loop outside the conduit, the tester shows the length
up to the service loop. This is true even if the two sections of
conduit are electrically connected.
Inventory Management
The tester is an inventory management tool. It measures
lengths of wire or cable while still on the spools.
The ability to measure the length of multi-conductor cable
remaining on its spool is valuable for both job-site and
warehouse personnel. Remember that with the TS90, you
can measure the length from JUST ONE END of a PAIR of
wires, allowing you to take inventory without unspooling
the cables or even having to move the spools at all.
