A broad-range measuring device allows for use of the test instrument in all alternating and 3-phase electrical systems with voltages from 65 to 500 V and frequencies of 15.4 to 420 Hz.
- Loop and line impedance measurement
- Measurement of insulation resistance using nominal voltage, with variable or rising test voltage
- Low-resistance measurement
- Earth resistance measurement
- Standing-Surface Insulation MeasurementBLUETOOTH Interface Logo
- Universal connector system
- Standard-compliant Testing of Electric Vehicle Charging Stations in accordance with IEC 60364-6 and IEC 61851
>
Testing of residual current devices (RCCBs)
- Measurement of contact voltage without tripping the RCCB
- Contact voltage is measured with reference to nominal residual current using 1/3 of the nominal residual current value
- Tripping test with nominal residual current, tripping time measurement
>
Special testing for systems and RCCBs
- Testing of equipment and RCCBs with rising residual current including indication of tripping current and contact voltage at the moment the RCCB is tripped
- Testing of RCCBs with: 1/2x, 1x, 2x, 5x IΔN
- Testing of RCCBs which are suitable for pulsating residual direct current, testing is conducted with positive or negative half-waves
- Testing of RCCBs with adjustable residual current for determining contact voltage
>
Testing for special RCDs
- Selective S, SRCDs, PRCDs (Schukomat, Sidos and others), types G/R, AC, A, F, Type B, B , EV
