GENERAL DESCRIPTION
The DET14C and DET24C represent a new generation of
earth/ground clamp-on resistance testers. These instruments
induce a test current into earth systems and measure ground
resistance in multi ground installations without needing to
disconnect the ground. They offer market leading access,
advanced features, simple operation and CAT IV 600 V safety
protection.
Designed with flat core ends, they prevent dirt build up,
ensuring measurement integrity and improved reliability over
products with interlocking teeth. Other enhancements over
current generation products include improved accuracy and up
to 300% increase in battery life. In electrically noisy
environments the built-in filter function offers increased noise
immunity.
DET14C and DET24C also offer a true RMS AC current
measurement facility up to 35 Amps. The instrument’s ability to
measure current flowing in an earth cable is a useful safety
feature, especially if the earth cable has to be disconnected. A
high current flow to earth could draw an arc on disconnection
with potentially severe consequences.
The elliptical shaped head design offers improved access to
cables and earth straps in constrained spaces (locations). The
clamp head accommodates up to 39 mm diameter cable and
50 mm earth tapes making them suitable for use in power
stations, sub-stations, towers and many more facilities. Operation
in dark and restricted areas is facilitated by a display with
backlight and an audible tone associated with the hold key. (The
special jaw opening mechanism ensures proper jaw closure yet
minimises the force required to open them).
The DET14C offers storage of results for later on-screen recall
and the DET24C supports a download of results via IrDA-to-USB
link into PowerDB and Power DB Lite, Megger’s Acceptance &
Maintenance Test Data Management software. Stored data is
indexed using a sequential serial number together with a time
and date stamp for each record.
