The MI 3123 SMARTEC Earth / Clamp is an earth resistance tester with the ability to perform 4-wire earth resistance measurement and 4-wire specific earth resistance measurement. MEASURING FUNCTIONS • Earth resistance, 4-wire method • Earth resistance, 4-wire method with one current clamp (option) • Earth resistance, two clamps method (option) • Specific earth resistance • TRMS current (option) KEY FEATURES • Earth resistance measurement: instrument performs standard 4-wire earth resistance tests with two earthing rods and specific earth resistance measurement • Selective earth resistance test: optional 4-wire earth resistance measurement in combination with an additional current clamp is used for measuring earth resistance of individual earthing rods • Contactless earth resistance test: earth resistance measurement with 2 current clamps without breaking the loop is intended for measuring resistance of individual earthing rods and is recommended first of all for urban areas • Downloadable: downloads via RS-232 or USB cable directly to the PC with the help of the optional software • Upgradeable: if changes occur to the regulations upgrades can be made to the firmware to keep the instrument up to date • Help screens: instrument comes complete with built-in help screens for referencing on site • Built-in charger & rechargeable batteries: instrument has a built-in charging circuit and comes complete with a set of rechargeable NiMH batteries • Custom limits: the limits can be set on any function, in that case large green and red lights of the LEDs will indicate a PASS or FAIL evaluation of test result
