MI 3123 SMARTEC Earth Clamp
Single-functional testers
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. With the optional A 1018 and A 1019 current clamps the instrument can perform 4-wire earth resistance measurement with one current clamp, contactless earth resistance testing with two clamps and TRMS current measurement up to 20 A. Configurable limits enable a PASS / FAIL evaluation of test results. All the results can be saved on the instrument and then downloaded via the optional software for evaluation and professional report generation after testing. The lightweight design, large bright LCD screen, built-in help screens, optional downloading via RS232 or USB ports and overvoltage category CAT IV make the MI 3123 an incredible earth resistance measuring instrument.

Properties
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 RS232 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.
- Easy to use: large bright LCD display and large buttons enable easy handling of the instrument (even while wearing gloves).
- Magnetic holder: magnet for fixing instrument on metal surfaces enables hands-free operation.
