240/415 V (operating range 180…440 V).
• Operating frequency 45…65 Hz
• Calculation of Ik fault current.
• Automatic differentiation between phase and phase-to-phase voltage.
• Possibility of applying test leads: 1.2 m, 5 m and longer.
• Measurement with swapped L and N conductors.
• Measurement of resistance (RS) and reactance (XS) components
Additional features
• Voltage measurement 0…440 V AC.
• Power supply: batteries (4 x LR6) or rechargeable batteries (4 x NiMH).
Application
This meter is designed for measurements on objects protected by
circuit breakers with rating up to 63 A, where fault currents reach
1 kA, i.e. in housing industry, single and multi-family houses, office
buildings, small factories and all other facilities that are equipped
with low-voltage electrical systems. In addition, the meter is a useful
tool for maintenance services.
