ROFITEST MBASE , add. trip test for RCDs and loop resistance test without tripping the RCD, E-mobility test, Bluetooth, ISO17025 Calibration
- 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 measurement
- Universal connector system
- 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.
- Testing for N-PE reversal
- Tripping test with nominal residual current, trip time measurement
- Testing of equipment and RCCBs with rising residual current including indication of tripping current and contact voltage
- Testing of RCCBs with nominal current of ½ • IΔN, 1 • IΔN, 2 • IΔN, 5 • IΔN to 100 mA
- Testing of selective type G/R, type AC, type A, F; type B, B+ and type EV
- Testing of RCCBs which are suitable for pulsating residual direct current; te
