SECTION IV
OPERATION
WARNING
Multi-function Instruments (VOM's) such as the 260-7P
and 7-PM are intended as general purpose measuring In-
struments for use in low power circuitry such as found
in consumer appliances, TV and radio receivers, and in
general laboratory applications. Their use is not recom-
mended in high voltage, high power circuitry where oper-
ator errors and inadequate personal protective measures
could result in serious injury from arcing or explosion.
Such circuitry is found in industrial or commercial appli-
cations such as induction (r-f) heaters and broadcast
transmitters, power substations and distribution centers,
X-ray equipment, large motor controls and the like.
Working in the high voltage section of such equipment
requires single-function, often specially designed instru-
ments used by specially trained personnel using appro-
priate protective equipment and procedures.
