NEW... Contractor Series Earth/Ground Resistance Testers MEGGERDET4TD2 ~ DET4tR2 ~ DET4tc2 ~ DET4tCR2 Plus Clamps & Kits
Four New DET4T2 Ground Resistance Tester Models
MEGGER’s popular DET4T Ground Resistivity Test Sets instrument family has grown to include 4 new models:
 DET4TD2: Digital Ground Resistance Tester with a fourth terminal for the measurement of soil resistivity, Dry-cell battery powered
DET4TC2: Dry-cell battery powered 4-terminal tester
with selectable test frequencies, greater
measurement sensitivity and attached rod
technique and stakeless measurement
capability
DET4TCR2: Rechargeable battery powered 4-terminal
tester with selectable test frequencies,
greater measurement sensitivity and
attached rod technique and stakeless
measurement capability
ART (Attached Rod Technique) Capability
The MEGGER DET4TC2 and DET4CR2 Ground Resistance Testers include the ART (Attached Rod Technique) testing capability. With the added function of current measuring for ART, on-site grounds can be tested separately without having to remove the utility connection. The new DET4TC and DET4TCR also provide a stakeless testing technique. It allows the operator to use the instrument like a clamp-on ground tester in applications where that method is viable, while also being able to operate as a fall of potential tester.
Complete MEGGER DET4T2 Kits Available
The DET4TC2-KIT and DET4TCR2-KIT are a complete kit of instrument, test leads, stakes, batteries, and calibration certificate are delivered in a tough polypropylene carry case – everything you need to start testing in one package. (Certificate not included with analog model). Optional terminal adapters are available for acceptance of a variety of test leads. All models are rated to IP54, making them truly outdoor instruments. They are designed to meet stringent safety standards and are rated CATIV 100V. The ground testers have been designed to be easy to use – a large selector switch makes selection of 2, 3 or 4 pole tests easy with gloved hands – and the design makes the fitting of shorting links to perform 2-pole tests a thing of the past.
MEGGER DET4T2 Series Feature Large Easy-to-Read Display
A large, clear, easy to read LCD display and thumb sized test button also make the instruments particularly well suited to the outdoor conditions of ground testing. In addition to this ease of use feature, the ground tester automatically checks the connection and conditions of the P spike, C spike, and also the level of ground noise, indicating the status on the display. (The analog model allows the operator to check the condition of the spikes). The instruments also include a voltmeter to enable measurement of ground voltage. The new DET4TC and DET4TCR also feature a backlit display, which extends the operational environment of the instrument to cable cellars and other dark locations. Finally, they also have selectable 25 V or 50 V output for compliance with IEC 61557-5.
Resistance Measurements from 0.01Ω to 20KΩs
The MEGGERMegger DET4TD2 and DET4DTR2 can measure resistance from 0.01Ω to 20KΩ, while the DET4TC2 and DET4TCR2 can measure resistance from 0.01Ω to 200KΩs. Also, to allow accurate testing in noisy environments, the instruments are capable of rejecting noise up to 40Vp/p.
Battery Powered Portable and Rugged
The Megger digital and analog ground testers are powered by eight AA batteries which are widely available and also give excellent testing time – the status of these batteries is given by a bar graph on the LCD display, allowing the operator to decide when to change the batteries before they expire. (On the analog model, battery status is indicated by selecting the function on the selector switch). Also, the new DET4TCR2 is powered from rechargeable AA cells. The battery charger is built in and the instrument is supplied with an AC/DC adapter. For all instruments, the battery status is displayed using a bar-graph.
Electrode Testing Without Disconnection
The new MEGGER DET4TC and DET4TCR also have additional capabilities. By using the optional ICLAMP the user can augment the traditional fall-of-potential measurement method with ART (Attached Rod Technique), which allows electrode testing without disconnection and also leakage current measurements down to 0.5 mA. A second optional clamp, the VCLAMP, enables true stakeless measurements to be made in situations where driving stakes is not practical.
