100A Digital Micro-Ohmmeter MPK102e

The MPK102e high current micro-ohmmeter is a portable, microprocessor-controlled instrument. It is used to accurately measure very low contact resistances of breakers and switches, busbars, transformers winding and engines, etc, with test currents from 1 mA to 100 A. 

- Microprocessor controlled

- Alphanumerical display

- Resolution down to: 0.1

 - Resistance reading up to: 200 

- Up to 100 A test current

- Kelvin-type (4 - wires) measurement

- Powered by internal battery (up to 10A) or mains supply

- Direct reading (up to 4 digits)

- Overheating protection

- Serial data output (USB)

It employs the 4 terminals-method to avoid measurement errors caused by test leads and their contact resistances. Using its internal rechargeable battery, measurements with up to 10 A test current may be carried out without connecting the equipment to mains supply. It measure with any test current up to 100 A by mains supply. Measurement accuracy is guaranteed by an state-of-the-art signals amplification system, offset-free and of high long-term stability. Test current may be adjusted by the operator and their values are measured using an analog indicator (bargraph). It makes it easy to measure resistances with a significant inductive component, as in the case of big transformers windings. Internal thermal sensors in all sensitive components avoid any damaged caused to the instrument due to overheating.

    Test voltage

    1 mA, 10 mA, 100 mA, 1 A, 10 A, 100 A
    Each current may be continuously adjustable from 0 to 100 %.

    Resistance ranges

    Current Range Resolution
    100 A 0-199.9 µΩ 0.1 µΩ
    100 A 0-1999 µΩ 1 µΩ
    10 A 0-1999 µΩ 1 µΩ
    10 A 0-19.999 mΩ 1 µΩ
    1 A 0-19.99 mΩ 10 µΩ
    1 A 0-199.99 mΩ 10 µΩ
    100 mA 0-199.9 mΩ 100 µΩ
    100 mA 0-1999.9 mΩ 100 µΩ
    10 mA 0-1999 mΩ 1 mΩ
    10 mA 0-19.999 Ω 1 mΩ
    1 mA 0-19.99 Ω 10 mΩ
    1 mA 0-199.99 Ω 10 mΩ
    For each test current, ranges are automatically selected for optimal reading.

    Measurement principle

    Four-terminal, Kelvin-type.

    Continuous operation time

    At 100 A this equipment may be used continuously for approx. 15 minutes before the thermal protection activates.
    At 10 A or less, there is not a limited time for continuous operation.

    Thermal protection

    Protects all sensitive components, avoiding any damage due to overheating.

    Basic accuracy

    R < 0.5 mΩ: ± (0.50 % of reading + 2 ULSD*).
    R ≥ 0.5 mΩ: ± (0.20 % of reading + 2 ULSD*).
    * Units of the Least Significant Digit.

    Advanced features

    Digital direct reading of very low resistances in the alphanumerical display, with up to 4½ digits. Very fast and accurate measurements.

    Test current measurement

    The current is digitally measured and a bargraph shows the result. The bargraph indication is specially useful when measuring inductive loads, so that the operator can verify easily when the test current has been stabilized.

    Interface

    USB.

    Environmental protection

    IP65 (with closed lid).

    Safety class

    Meets the requirements of IEC 61010-1.
