AC Current Oscilloscope Probe Model MN261
PRECAUTIONS FOR USE
These safety warnings are provided to ensure the safety of personnel and
proper operation of the instrument.
Connect the probe to the oscilloscope or voltage measuring instrument
clamping the probe around a conductor.
Never use the probe on circuits rated higher than 600V, Cat III.
Never leave the probe clamped around a conductor while not connected
to an oscilloscope or voltage measuring instrument.
Carefully center the conductor inside the probe jaws and ascertain that
the probe is perpendicular to the conductor.
Avoid, if possible, the proximity of other conductors which may create
noise.
free of dirt, rust, or other foreign matter.
Do not use a probe which is cracked, damaged, or has defective leads.
Upon receiving your shipment, make sure that the contents are consistent
with the packing list. Notify your distributor of any missing items. If the equip-
notify your distributor at once, giving a detailed description of any damage.
Save the damaged packing container to substantiate your claim.

AC Current Oscilloscope Probe Model MN261
7
The AC Current Oscilloscope Probe Model MN261 expands oscilloscope
applications in industrial or power environments, and is ideal for analysis
and measurement of distorted current waveforms and harmonics.
The Model MN261 permits accurate display and measurement of currents
from (0.1 to 240) Arms, 40 Hz to 10 kHz (with current derating) without
rising (di/dt) waveforms, and ensures accurate screen displays.
The probe connects directly to an oscilloscope through an insulated coax-
ial cable with an insulated BNC.
The Model MN261 is compatible with any analog or digital oscilloscope
or other voltage-measuring instrument which has the following features:
• BNC input connector
• Range capable of displaying (0.2 to 0.5) V per division, or 2 V range
• Minimum input impedance of 1 M
