- Digital clamp meter measures ground resistance and current in multi-ground installations without needing to disconnect the ground.
- Provides true RMS (root mean square) measurements of current to help ensure operator safety during operation.
- User-selectable noise filter allows measurements to be taken in areas with high as of electrical noise.
- Data storage allows multiple results to be compared and tracked over time.
- Meets International Electrotechnical Commission (IEC) safety standard 61010 and is certified for category IV installations up to 600V.
The Megger DET14C digital clamp-on ground resistance meter
measures ground resistance and current in multi-ground electrical
installations and lightning protection systems without needing to
disconnect the ground. 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 for future reference. 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. The Megger DET14C 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.
