The CEM DT-5301 is a professional loop impedance and prospective short-circuit current (PSC) tester for electrical installation verification and fault finding. It combines low-resistance loop testing, direct PSC calculation and wiring-status checks in a compact handheld instrument.
Key Features
- Loop impedance ranges: 20 Ω, 200 Ω and 2000 Ω
- 0.01 Ω resolution on the low loop range
- Direct PSC measurement up to 20 kA
- 15 mA low-current loop measurement on the 2000 Ω range
- Three LEDs for checking wiring status
- Visual warning for reversed phase and neutral
- Automatic lock-out if the internal test resistor overheats
- Voltage measurement from 50 to 250 V
- IEC 61010-1 CAT III 600 V safety rating
Applications
- Electrical installation testing
- Earth-fault loop impedance checks
- Prospective short-circuit current assessment
- Socket wiring verification and fault finding
