Aemc instruments MN05 User Manual

AC Current Probe
Model MN05

User Manual

DESCRIPTION

The MN05 (Cat. #2129.19) is small, compact AC current probe. Designed to meet the most stringent
demands in industry and electrical contracting, they also meet the latest safety and performance
standards. The probe has two measurement ranges (10 and 100Arms) which makes it a perfect tool for
measurement with DMMs, recorders. The Model MN05 is compatible with any voltmeter, multimeter, or
other current measurement instrument with an input impedance greater than 1M. To achieve the
stated accuracy, use the probe with a voltmeter having an accuracy of 0.75% or better.

DEFINITION OF MEASUREMENT CATEGORIES

CAT II: For measurements performed on circuits directly connected to the electrical distribution system.

Examples are measurements on household appliances or portable tools.

hardwired equipment in fixed installation and circuit breakers.

CAT IV: For measurements performed at the primary electrical supply (<1000V) such as on primary

overcurrent protection devices, ripple control units, or meters.

RECEIVING YOUR SHIPMENT:

Upon receiving your shipment, make sure that the contents are consistent with the packing list. Notify
your distributor of any missing items. If the equipment appears to be damaged, file a claim immediately
with the carrier and notify your distributor at once, giving a detailed description of any damage.

Making Measurements with the AC Current Probe Model MN05

 Connect the black lead of the current probe to “common” and the red lead to the AC voltage range on

your DMM or other voltage measuring instrument. The “10A” range has an output signal of 1mV/mA
AC. This means that for 10A AC in a conductor around which the probe is clamped, 10V AC will come
out of the probe leads to your DMM or instrument. The “100A” range has an output signal of 1mV/A
AC. This means that for 100A AC in a conductor around which the probe is clamped, 100mV AC will
come out of the probe leads to your DMM or instrument. Select the range on your DMM or instrument
which corresponds best to the measured current. If the current magnitude is unknown, start with the
highest range first and work down until the appropriate range and resolution is reached. Clamp the
probe around the conductor. Take the reading on the meter and multiply it by the output signal used to
obtain the measured current. (e.g. If the meter reads 100.5mV [range 1mV/mA], then current equals

100.5mA AC). Unclamp the probe from the conductor before disconnecting it from your DMM or
instrument.

• For best accuracy, avoid if possible, the proximity of other conductors which may create noise.

Tips for Making Precise Measurements

• When using a current probe with a meter, it is important to select the range that provides the best
resolution. Failure to do this may result in measurement errors.

• Make sure that probe jaw mating surfaces are free of dust and contamination. Contaminants cause air
gaps between the jaws, increasing the phase shift between primary and secondary. It is very critical for
power measurement.

MAINTENANCE:
Warning

• For maintenance use only original factory replacement parts.

• To avoid electrical shock, do not attempt to perform any servicing unless you are qualified to do so.

• To avoid electrical shock and/or damage to the instrument, do not get water or other foreign agents
into the probe

Cleaning

To ensure optimum performance, it is important to keep the probe jaw mating surfaces clean at all times.
Failure to do so may result in error in readings. To clean the probe jaws, use very fine sand paper (fine

600) to avoid scratching the jaw, then gently clean with a soft oiled cloth.

REPAIR AND CALIBRATION

You must contact our Service Center for a Customer Service Authorization number (CSA#). This will
ensure that when your instrument arrives, it will be tracked and processed promptly. Please write the CSA#
on the outside of the shipping container.
