Circuit Analyzer Mastech TRMS AC Low Voltage Distribution Line Fault Tester RCD GFCI Sockets Testing  MS5908B ASTECH 

1. Measurement of AC voltage with true RMS
2. Simulated load 5A, 8A, 10A, measure line voltage drop
3. Measure phase voltage, neutral line (zero line) to ground voltage, peak voltage and frequency
4. Measure conductor impedance of phase line (live line) and neutral line (neutral line)
5. Identify the wiring mode of 3-wire socket (left zero and right fire, with or without ground wire)
6. Test whether the leakage protector is reliable and the action response time
7. Backlight illumination and data retention function
