This device cannot be used with exposed conductors, so please
use it with insulated conductors. Insulation must meet the
requirements of the measurement category, working voltage,
and pollution degree of the circuit being tested.
*
Maximum continuous input range:
This range is based on heat that is internally generated during
sine wave input at a prescribed frequency at room tempera-
ture. It varies according to the frequency of the measured
current. (Use the 9754 CLAMP ON NOISE SENSOR at the
highest effective value within the maximum continuous input
range.) In addition to the maximum continuous input range,
there is also the "maximum peak current value 15 Apeak"
product specification. This indicates an upper waveform
response limit of 15 Apeak.
Measurement
Chapter 2
• To avoid electrical shock, be careful not to
damage the insulation of the conductor
being measured.
• Do not measure around a bare conductor.
Doing so may result in short-circuit or elec-
tric shock. Take measurements at a loca-
tion on an insulated wire where there is
sufficient insulation for the circuit voltage.
To avoid electric shock when measuring live
lines, wear appropriate protective gear, such
as insulated rubber gloves, boots and a
safety helmet.
To avoid damaging the unit, do not apply current
that exceeds the maximum continuous input
range. (
