Key Features- Insulation resistance: Measurement up to 1000V DC, including calculations for the Dielectric Absorption Ratio (D.A.R.) and Polarization Index (P.I.).
- Continuity: Test of protective and equalizing conductors with 200mA DC.
- Earth resistance: Methods include overall earth resistance (without tripping the RCD), voltammetric measurement, and resistance of individual earth rods with an optional clamp.
- RCD testing: Tripping time and current for Type B, A, and AC RCDs.
- Impedance: Loop/line impedance with calculation of prospective short-circuit current.
- Phase sequence: Verification of correct phase rotation.
- "AUTO" function: This innovative feature automates a sequence of tests—including non-trip earth resistance, RCD tripping time, and insulation resistance—requiring the operator to set only the value of the RCD current.
