The DT-5301 is designed for electricians, inspectors, and maintenance engineers who need to verify the safety and performance of electrical installations. It measures loop impedance (L-PE and L-N) and provides direct readings of Prospective Short Circuit Current (PSC), helping users assess fault conditions and compliance with electrical safety standards.
The instrument features a low-current 15mA loop test mode, allowing measurements on protected circuits without unnecessarily tripping RCD devices. Additional functions include voltage measurement, wiring verification LEDs, reverse polarity indication, and automatic overload protection for safe and reliable operation.
