Product BrochureProduct Details:

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 an 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 the 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 dis-connection with potentially severe consequences. The elliptical-shaped head design offers improved access to cables and earth straps in space-constrained locations. The clamp head accommodates up to 37 mm diameter cable and 50 mm earth tapes making them suitable for use in power stations, substations, towers, and many more facilities. Operation in dark and restricted areas is facilitated by a display with a backlight and an audible tone associated with the hold key. An optimized jaw opening mechanism ensures proper jaw closure without excessive use of force when opening the jaws. The DET14C offers storage of results for later on-screen recall and the DET24C supports a download of results via Bluetooth® into PowerDB and PowerDB Lite, Megger’s acceptance and maintenance test data management software. Stored data is indexed using a sequential serial number together with a time and date stamp for each record. Application of the earth resistance clamp meters is particularly suitable for measuring earth resistance in various installations such as buildings, pylons, and RF transmitter sites without system disconnection. In addition, they can be used for the inspection and verification of lightning protection systems and virtually any installation where a current loop can be generated.
