Optional method for testing elbow/cable without using a feed-thru device:
One worker uses an elbow-puller tool to control elbow while another
worker tests it with elbow adapter fitted on MRVD.
(Elbow adapter T403-0856 and bushing adapter T403-0857 furnished
with MRVD model T403-2271)
6.
Multiply readings by the factor given at the switch position selected.
(if readings are low on scale, set switch to next lower voltage range and
repeat tests).
If in doubt about interpreting MRVD reading under any circumstance,
assume circuit is energized and take appropriate safety precautions.
Elbow Test-Point Method
(only MRVD Models C403-0979, T403-2271,
and PSC4031029TP)
1. Same as Step 1 above. Do not skip this.
2. Thread straight probe into end fitting and
mount MRVD on proper length hot stick. Set
selector at "TP" position.
3. With hot-line tools, pull cap off test point*
and contact it with probe.
4. Meter should read circuit condition. Any
deflection, when set at the highly-sensitive "TP"
position, indicates an energized condition.
*Test point must be free of corrosion for test
continuity.
Do not let universal fitting touch any part of URD cabinet or to become
grounded in any other way. This will damage meter and may cause injury.
