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

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
