1 TEST EQUIPMENT GROUND RESISTANCE GROUND TESTERS Megger is the expert i groud resistace testig. From time savig clamp-o groud testers to specialty models for high sesitivity testig, we have the groud resistace tester to fit your applicatio ad budget. The Megger lie of groud resistace testers provides high accuracy, a broad testig rage ad fast, reliable measuremets. Megger groud testers are easy to use ad lightweight. The ext few pages will outlie the full lie of groud testig equipmet that Megger has to offer. Our staff of professioals will help with your techical groudig questios ad recommed the groud tester that best fits your eed. Call us at or search the web at us.megger.com. DET3 CONTRACTOR SERIES The DET3 Series of digital groud testig istrumets from Megger is comprised of two models: a istrumet for groudig ad bodig tests ad a uit that adds a curret measurig fuctio. With this added fuctio, curret o the groud rod ca be measured for improved persoel safety ad oise detectio. The DET3TC icludes the ART (Attached Rod Techique) method of testig which greatly reduces testig time. These Megger digital groud testers are powered by eight AA batteries which give excellet testig time the status of the batteries is give by a bar graph o the LCD. The Megger DET3 Series earth/groud testers is desiged to meet striget safety stadards ad is rated CAT IV 100V. Each DET3 comes complete with test leads, stakes, batteries, calibratio certificate ad rugged polypropylee carry case.

2 DET4T2 ENHANCED SERIES These groud testers from Megger offer a comprehesive solutio to groud resistace ad soil resistivity testig eeds. The istrumets provide such fuctios as 2 pole, 3 pole, 4 pole, Attached Rod Techique (ART), stakeless, leakage curret ad groud oise voltage measuremets. All models ow iclude selectable output voltage (25 V or 50 V). The DET4TC2 ad DET4TCR2 offer four selectable test frequecies (94, 105, 111 ad 128 Hz) for improved testig i oisy eviromets. A optioal ICLAMP augmets the traditioal fall-of-potetial measuremet method with ART which allows electrode testig without discoectio ad also leakage curret measuremet dow to 1 ma. The VCLAMP, a secod optioal clamp, eables true stakeless measuremets to be made where drivig a stake is ot practical. The DET4TC2 ad DET4TD2 are powered by eight AA batteries which give excellet testig time. The DET4TR2 ad DET4TCR2 are powered from rechargeable AA cells. For added coveiece o all four uits, the battery status is displayed usig a bar graph. The Megger DET4T2 Series earth/groud testers is desiged to meet striget safety stadards ad is rated CAT IV 100V. THE ART OF GROUND TESTING Groud testig usig the ART (Attached Rod Techique) method is more coveiet ad reduces testig time. Models DET3TC, DET4TC2 ad DET4TCR2 iclude this additioal testig capability. A aggig problem with traditioal groud testig has bee the requiremet to discoect the utility coectio. Usig the ART method you ca reliably measure a groudig electrode while still coected ad prove it! The ART method is more coveiet ad sigificatly reduces your testig time as much as 40 percet! The DET4TC2 ad DET4TCR2 offer ART capability as well as stakeless testig ad of course 4, 3 ad 2 pole testig. WHAT S IN THE DET4T NAME?

4 DET14C AND DET24C CLAMP-ON EARTH/GROUND TESTER The DET14C ad DET24C are advaced clamp-o groud testers used for measurig resistace of groud rods ad associated istallatios. These istrumets iduce a test curret ito groud systems ad measure groud resistace i multi-earth istallatios without the eed to discoect the electrical system. The techique effectively measures a loop resistace. Hard-to-reach groud spikes are easily accessed with the istrumets short body legth, a uique pre-test hold fuctio, ad display backlight for low light eviromets. The elliptical head shape greatly improves capacity eablig roud cables up to 37 mm diameter ad earth tapes (flat strip coductors) up to 50 mm wide to be clamped. Good reliability is provided with smooth, flat core matig surfaces to prevet dirt build-up ad esure measurig itegrity, ad a extremely high battery life (24 hours cotiuous). Both istrumets feature date- ad time-stamped test result storage reviewable o the large dual display. The DET24C offers a larger memory plus PC dowload capability. Elliptical clamp shape with 39 mm x 55 mm ier jaw dimesios. Low maiteace flat jaw iterface. Excellet safety ratig of CAT IV 600V. Automatic oise curret warig safety feature.
