DET10C, DET20C
Earth/Ground Resistance & Leakage
Current Clamp Testers
DESCRIPTION
The Megger models DET10C and 20C measure
earth/ground resistance and current flow using clamp-on
technology. The instruments induce a test current into the
system without the need to disturb existing connections.
Either unit is a useful addition to the more traditional
methods of earth/ground resistance testing that may
require disconnection and the use of stakes or ground
rods. Simply clamp around the conductor or stake/rod
and measure the resistance to ground fast and accurately.
The DET10C and 20C can also be used to measure
earth/ground resistance in multiple loop installations
without disconnecting the earth or ground. This allows
the user to perform the test quickly and easily in total
safety, with the added convenience of having a single
point of measurement to read the earth/ground resistance.
Each instrument also provides a true RMS current
measurement reading to better indicate potential
measurement problems and provide a useful overview of
the dynamics of the general earth/ground system.

The units are rugged, compact and have configurable
audible alarms. They also feature auto shutdown (which
is also configurable), data storage and self calibration on
power-up, and are supplied with a calibration loop – all
contained in a rugged carry case. The DET20C also comes
with a USB interface cable and is compatible with Megger
Download Manager Software (included) allowing further
analysis and storage of data.
APPLICATION

Use to measure resistance and continuity of grounding
loops around pads and buildings.
Use on multi-grounded systems without disconnecting
the ground rod/stake under test.
Use to measure leakage current flowing to ground or
circulating in ground systems.
Use on cell towers, RF transmitters and
telecommunications sites.
Use to inspect and verify lightning protection systems.
Use on a variety of consumer installations, including
pools, spas, etc.
Measure shield leakage current to ground for shield
continuity checks
