Biddle Four-Terminal Ground/Earth Resistance Tester DET 5/4 Description Click here to view full-pdf specification sheets The DET5/4D and DET5/4R are fully automatic, four terminal instruments built into a rugged, water resistant case giving protection for outdoor use. The instrument is suitable for the testing of earth electrodes and measuring earth resistivity. MEGGER DET5/4D and DET5/4R Simple, fully automatic operation Choice of three- or four-terminal measurement Autoranging from 10 m W to 20 k W The DET5/4D and DET5/4R ground testers provides the higher resistance range necessary for the testing of ground electrodes and measuring ground resistivity. The fully automatic operation is started by simply choosing a three- or four-terminal measurement, all other operations are automatic. These instruments are suitable for soil resistivity measurements used to establish the optimum ground electrode system design and location, and archaeological and geological investigations. There are four ranges covering measurements from 10 m W to 20 Features • Simple to use, one touch operation • Auto switch off to save battery power • Rugged, weatherproof case • Large, clear L.C.D. • Noise rejection to 40 V • Indicators show if reading may be invalid • Terminal shorting bars supplied • Earth testing kits available • Optional carrying case and harness Specifications Earth Resistance Ranges (Autoranging) 20 ½ Range: 0,01 ½ to 19,99 ½ 200 ½ Range: 0,1 ½ to 199,9 ½ 2 k½ Range: 0,001 k½ to 1,999 k½ 20 k½ Range: 0,01 k½ to 19,99 k½ Accuracy (at 23°C) ±2 % of reading ±3 digits Maximum service error ±5% of reading ±3 digits. Display 3 1/ 2 digit L.C.D. with ½, k½ and low battery voltage indicators. LEDs for high noise, high voltage probe resistance and high current loop resistance. Test Frequency 128 Hz ±0,5 Hz Test voltage Maximum 50 V peak.
