  • Description:
    • The MPK105x high-current micro-ohmmeter is a portable, microprocessor-controlled instrument. Has optimized filters and protections for measurements in electrical substations.
    • It employs the 4 terminals-method (U/I measuring principle) to avoid errors caused by test leads and their contact resistances.
    • Measurement accuracy is guaranteed by a state-of-the-art signal amplification system, offset-free and of high long-term stability.
    • Resistances readings are shown in the alphanumeric display with up to 4½ digits-resolution.
    • It allows to measure resistances up to 300 mΩ, and the best resolution is 0.1 µΩ.
    • Test current may be adjusted by the operator and his value is measured using an analog indicator (bargraph).
    • It has an internal memory for up to 50 registers with 80 readings each.
    • The serial data output (USB) may be connected to a computer to download the stored values.
    • The high-current generation system is based on modern technology that allows to significantly decrease both its weight and size.
    • The cabinet is made of plastic material highly resistant to impacts and to environmental challenges.
    • Internal thermal sensors in all sensitive components avoid any damage caused to the instrument due to overheating.
