Product Description: How to Translate
This circuit analyzer is a specialized testing instrument designed for fast fault location of AC low-voltage distribution lines, with operation capabilities
The characteristics of simplicity and accurate measurement enable timely detection of circuit problems such as electric shock to personnel, electrical fires, and abnormal equipment operation.
|
Features: |
·True RMS measurement of AC voltage |
·Simulate loads of 5A, 8A, and 10A, measure the voltage drop of the circuit |
·Measure phase voltage, neutral (neutral) to ground voltage, peak voltage, and frequency |
|
·Measure the impedance of phase (live), neutral (neutral), and ground conductors |
·Identify the wiring method of the 3-wire socket (left zero, right fire, with or without ground wire) |
·Test the reliability and response time of residual current devices (RCD or GFCI) |
·Backlight illumination and data retention function |
|
