1. Install the instrument.
2. Install the included ferrite cores on the AC adapter and the Clamp on Noise
Sensor
Loop the output side of the cable through the ferrite core twice and then close
it until you hear a snap.

Instrument
10 cm or more
Ventilation holes
• Vents must not be obstructed.
• The instrument should be operated
only with the bottom side down-
wards.
• Do not place on an unstable stand or
on an incline.
(AC adapter shown here)
Install as close as possible to
the pre-installed ferrite core.

3. Connect the 9418-15 AC ADAPTER to the instrument.
Plug the AC adapter into the power outlet.
• Turn the instrument off before connecting the AC adapter to the
instrument and to AC power.
• Use only the supplied Model 9418-15 AC ADAPTER. AC adapter
input voltage range is 100 to 240 VAC (with ± 10% stability) at 50/
60 Hz. To avoid electrical hazards and damage to the instrument,
do not apply voltage outside of this range.
Lower Panel
AC Adapter
Power Outlet
The instrument has dual power systems and you can supply it power
with both the AC adapter and the optional 9447 BATTERY PACK. You
can take measurements using only the AC adapter, but we recommend
installing and using the battery back as a preventative measure for
power supply interruptions.
For installing the battery pack and how to recharge it, refer to "2.4 Sup-
plying Power with the Battery Pack" in the instruction manual included
with the instrument.

Barrier
• To avoid electric shock, do not touch the portion beyond the pro-
tective barrier during use.
• To avoid short circuits and potentially life-threatening hazards,
never attach the clamp to a circuit that operates at more than
600 V (CAT II) / 300 V (CAT II ), or over bare conductors.
To avoid damaging the instrument, do not apply current that exceeds
the maximum continuous input range.
* Maximum continuous input range:
This range is based on heat that is internally generated during sine
wave input at a prescribed frequency at room temperature. 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 contin-
uous input range, there is also the "maximum peak current value 15
Apeak" product specification. This indicates an upper waveform
response limit of 15 Apeak.
