The AEMC 407 digital clamp-meter is a true RMS sensing,
auto-ranging multimeter for measuring current, voltage,
frequency, resistance, and power in electrical testing
applications. It has a clamp that measures AC (alternating
current) to 1,000A (ampere) and DC (direct current) to 1,500A.
The clamp has two jaws that can close around an electrical
conductor up to 48mm (1.89 inches) in diameter to measure current
without touching or interrupting the circuit. A set of test
leads, which are silicone-insulated for flexibility and
resistance to heat and cold, is included for measuring AC and DC
voltage to 1,000V, frequency to 20kHz (kilohertz), and resistance
to 100kΩ (kilohms). For power monitoring and analysis, the meter
measures THD (total harmonic distortion) which can degrade the
quality of the power being supplied by the system, analyzes
individual harmonics to the 25th order, calculates power factor
to determine how efficiently an installation uses power, and
measures single- and three phase real power to 3,000kW
(kilowatts), reactive power to 1,500 kilovar (kilovolt-ampere
reactive), and apparent power to 1,500kVA (kilovolt-ampere).
The meter has a rotary switch to select the property to measure,
and a three-line 10,000-count LCD with a backlight for visibility
in low light that turns off automatically after two minutes. For
data logging and analysis, the meter has a data
function that allows storage of up to 1,000 measurements, comes
with a wireless adapter for communicating with a PC, and includes
DataView software for downloading measurements from the meter to
generate reports. The software is compatible with Microsoft
Windows XP, Windows Vista, Windows 7, and Windows 8 with support
for 32- and 64-bit systems. The data storage rate is programmable
from one reading per second to one reading every 600 seconds. The
inrush current function, with a selectable sampling time of 1ms
(millisecond) or 100ms, analyzes surge current at startup and due
to load increases in installations that are up and running. The
delta relative function allows a measurement to be set as a
reference value and displays subsequent measurements as a
positive or negative deviation from that value. The
maximum/minimum function tracks the highest and lowest readings
for a property for as long as the function is engaged. To aid
documentation of readings and capture readings in tight spaces,
the data hold function keeps the most recent reading on the
display after disconnecting from the circuit. A continuity buzzer
confirms that the circuit conducts electricity. The unit operates
on four 1.5V AA batteries and turns off automatically after 10
minutes of non-use to conserve battery life.
This true RMS (root mean square) sensing meter provides accurate
readings when measuring linear or non-linear loads, regardless of
the waveform. It is auto-ranging, so it automatically selects the
appropriate operating range for the property being measured.
Accuracy and resolution ( https://images-na.ssl-images-.com/images/G/01/BISS/MixMeters2013/AEMC407.usermanual.pdf#page=65 ) specifications vary according to the range being measured. It
meets IEC (International Electrotechnical Commission) safety
standard 61010, and is rated for CAT (category) IV installations
to 1,000V, which covers equipment at the origin of the
installation, such as electricity meters and primary over-current
protection equipment. It has CE (European Conformity) marking and
is IP (Ingress Protection) 54 rated against dust and water spray.
The unit comes with a hard carrying case.

Clamp-meters, also called clamp-on meters, have two jaws that fit
around a conductor to measure electrical current without cutting
through wires, or touching or interrupting the electrical
circuit. Available in handheld or benchtop models, clamp-meters
diagnose problems in electrical equipment, wiring, and power
supplies. All clamp-meters test for current. Some come with test
leads and inputs for measuring voltage, capacitance, and
resistance. They display information either in analog or digital
form. Factors that influence meter choice include the electrical
properties to be measured, the anticipated range of results, and
the desired level of protection against transient voltage. Safety
ratings are based on International Electrotechnical Commission
(IEC) standards for low-voltage test equipment. IEC 61010
delineates four overvoltage installation categories. In general,
a meter with a category IV rating will provide more protection
against transient voltages than a meter with a lower category
rating.
