    • Resistances readings are shown in the alphanumeric display with up to 4½ digits-resolution.
    • It allows to measure resistances up to 20 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 200 readings.
    • The USB interface may be connected to a computer to download the stored values.
