The Megger DET24C digital clamp-on ground resistance meter
measures ground resistance in multi-ground electrical
installations and lightning protection systems without needing to
disconnect the ground in electrical testing applications. It has
a clamp with two jaws that can close around round cables and rods
up to 1.45" (37 mm) in diameter and ground tapes and straps up to
1.96" (50 mm) wide to measure resistance without disconnecting
the ground. The meter also provides true RMS (root mean square)
measurements of current up to 35 amp to help ensure operator
safety during operation. The meter has a user-selectable noise
filter to allow measurements to be taken in areas with high
as of electrical noise. The meter's internal data storage
allows multiple results to be compared and tracked over time, and
readings are date and time stamped. It comes with a software that
provides a graphic user interface for working with the data on a
computer. An alarm notifies user when user-selected minimum and
maximum values for current and resistance are reached or
exceeded. The hold function keeps a reading on the display, even
after the meter is disconnected. In applications where the
conductor is difficult to access, an auto-hold feature allows a
reading to be captured without requiring the operator to press
the button during measurement. The meter's liquid crystal display
(LCD) is backlit to provide readability in low light. The clamp
jaws have a smooth surface with no interlocking teeth to help
prevent build-up of dirt and residue, which can interfere with
measurements. The unit automatically turns off after five minutes
of non-use to conserve battery life, and a low-battery indicator
signals when the meter's batteries need to be replaced. This
Megger earth test clamp-on ground resistance meter meets
International Electrotechnical Commission (IEC) safety standard
61010 and is certified for category IV installations up to 600V,
which covers measurements at the source of the low-voltage
supply, such as electricity meters and overcurrent protection
devices. The meter has a wrist strap and comes with a hard
plastic carrying case to protect the meter from damage during
transport and storage. A finger guard on the body of the meter
helps protect fingers from shock.

Electrical test meters report electrical circuit properties, such
as voltage, resistance, capacitance, and continuity. Available in
handheld or benchtop form, they detect electrical problems in
equipment, wiring, and power supplies. A variety of probes,
clamps, and leads can be used to connect the meter to a circuit
or device. Single-function meters, such as battery testers and
voltage testers, measure one property of a circuit, and
multimeters measure multiple properties. Electrical test meters
display information either in analog form using a needle that
moves on a calibrated scale, or in digital form using digits or a
graphic representation on an LED screen. Meters have electrical
properties that are to be measured and the anticipated range of
results, and should have a rating that is higher than the maximum
value of the anticipated range. An electrical test meter has
multiple settings corresponding to potential ranges of values for
the properties it can measure. A manual ranging meter requires
the operator to flip through different settings until the correct
range is reached. An autoranging meter cycles through range
settings automatically until it reaches the correct range.
Megger manufactures equipment for cable fault locating,
protective relay testing, telecommunications and data integrity,
and power quality testing under multiple brand names, among them
Megger, Biddle, States, and AVO. The company, founded in 1889, is
headquartered in Dover, England, and meets International
Organization for Standardization (ISO) 9001:2008 standards.
