SECTION IV
OPERATION
WARNING |
Multi-function Instruments (VOM’s) such as the 270-5 are
intended as general purpose measuring Instruments for
use in low power circuitry such as found in consumer ap-
pliances, TV and radio receivers, and in general laboratory,
applications. Their use is not recommended in high volt-
age, high power circuitry where operator errors and inad-
equate personal protective measures could result in
serious injury from arcing or explosion. Such circuitry is
found in industrial or commercial applications such as in-
duction (r-f) heaters and broadcast transmitters, power
substations and distribution centers, X-ray equipment,
large motor controls and the like. Working in the high volt-
age section of such equipment requires single-function,
often specially designed instruments used by specially
trained personnel using appropriate protective equipment
and procedures.
